The directive supports both icon fonts and SVG icons.\n *\n * Icons should be considered view-only elements that should not be used directly as buttons; instead nest a ``\n * inside a `md-button` to add hover and click features.\n *\n * ### Icon fonts\n * Icon fonts are a technique in which you use a font where the glyphs in the font are\n * your icons instead of text. Benefits include a straightforward way to bundle everything into a\n * single HTTP request, simple scaling, easy color changing, and more.\n *\n * `md-icon` lets you consume an icon font by letting you reference specific icons in that font\n * by name rather than character code.\n *\n * When using font-icons, developers must follow three (3) simple steps:\n *\n *

Load the font library. e.g.
\n * ``\n *
\n * Use either (a) font-icon class names or (b) a fontset and a font ligature to render the font glyph by\n * using its textual name _or_ numerical character reference. Note that `material-icons` is the default fontset when\n * none is specified.\n *
Use any of the following templates:
\n *
- ``
- `textual_name`
- ` numerical_character_reference `
- ``
- ``
\n *

\n *\n * Full details for these steps can be found in the\n * \n * Material Design Icon font for the web docs.\n *\n * You can browse and search the Material Design icon style .material-icons\n * in the Material Design Icons tool.\n *\n * ### SVG\n * For SVGs, the problem with using `` or a CSS `background-image` is that you can't take\n * advantage of some SVG features, such as styling specific parts of the icon with CSS or SVG\n * animation.\n *\n * `md-icon` makes it easier to use SVG icons by *inlining* the SVG into an ``. `$mdIconProvider`, as a convenience, lets you _name_ an icon so you can\n * reference it by name instead of URL throughout your templates.\n *\n * Additionally, you may not want to make separate HTTP requests for every icon, so you can bundle\n * your SVG icons together and pre-load them with `$mdIconProvider` as an icon set. An icon set can\n * also be given a name, which acts as a namespace for individual icons, so you can reference them\n * like `\"social:cake\"`.\n *\n * When using SVGs, both external SVGs (via URLs) or sets of SVGs (from icon sets) can be\n * easily loaded and used.\n *\n * ### Localization\n *\n * Because an `md-icon` element's text content is not intended to be translated, it is recommended\n * to declare the text content for an `md-icon` element in its start tag. Instead of using the HTML\n * text content, consider using `ng-bind` with a scope variable or literal string.\n *\n * Examples:\n *\n *

\n * Click on the image above to open the\n * Material Design Icons tool.\n *

\n *\n * Click on any icon, then click on the \"Selected Icon\" chevron to see the slide-up\n * information panel with details regarding a SVG download and information on the font-icon's\n * textual name. This panel also allows you to select a black on transparent or white on transparent\n * icon and to change the icon size. These settings only affect the downloaded icons.\n *\n * @param {string} md-font-icon String name of CSS icon associated with the font-face will be used\n * to render the icon. Requires the fonts and the named CSS styles to be preloaded.\n * @param {string} md-font-set CSS style name associated with the font library; which will be assigned as\n * the class for the font-icon ligature. This value may also be an alias that is used to lookup the classname;\n * internally use `$mdIconProvider.fontSet()` to determine the style name.\n * @param {string} md-svg-src String URL (or expression) used to load, cache, and display an\n * external SVG.\n * @param {string} md-svg-icon md-svg-icon String name used for lookup of the icon from the internal cache;\n * interpolated strings or expressions may also be used.

Notes

\n *\n * - Requires [ngMessages](https://docs.angularjs.org/api/ngMessages).\n * - Behaves like the [AngularJS input directive](https://docs.angularjs.org/api/ng/directive/input).\n *\n * The `md-input` and `md-input-container` directives use very specific positioning to achieve the\n * error animation effects. Therefore, it is *not* advised to use the Layout system inside of the\n * `` tags. Instead, use relative or absolute positioning.\n *\n *\n *

Textarea directive

\n * The `textarea` element within a `md-input-container` has the following specific behavior:\n * - By default the `textarea` grows as the user types. This can be disabled via the `md-no-autogrow`\n * attribute.\n * - If a `textarea` has the `rows` attribute, it will treat the `rows` as the minimum height and will\n * continue growing as the user types. For example a textarea with `rows=\"3\"` will be 3 lines of text\n * high initially. If no rows are specified, the directive defaults to 1.\n * - The textarea's height gets set on initialization, as well as while the user is typing. In certain situations\n * (e.g. while animating) the directive might have been initialized, before the element got it's final height. In\n * those cases, you can trigger a resize manually by broadcasting a `md-resize-textarea` event on the scope.\n * - If you want a `textarea` to stop growing at a certain point, you can specify the `max-rows` attribute.\n * - The textarea's bottom border acts as a handle which users can drag, in order to resize the element vertically.\n * Once the user has resized a `textarea`, the autogrowing functionality becomes disabled. If you don't want a\n * `textarea` to be resizeable by the user, you can add the `md-no-resize` attribute.\n */\n\nfunction inputTextareaDirective($mdUtil, $window, $mdAria, $timeout, $mdGesture) {\n return {\n restrict: 'E',\n require: ['^?mdInputContainer', '?ngModel', '?^form'],\n link: postLink\n };\n\n function postLink(scope, element, attr, ctrls) {\n\n var containerCtrl = ctrls[0];\n var hasNgModel = !!ctrls[1];\n var ngModelCtrl = ctrls[1] || $mdUtil.fakeNgModel();\n var parentForm = ctrls[2];\n var isReadonly = angular.isDefined(attr.readonly);\n var mdNoAsterisk = $mdUtil.parseAttributeBoolean(attr.mdNoAsterisk);\n var tagName = element[0].tagName.toLowerCase();\n\n\n if (!containerCtrl) return;\n if (attr.type === 'hidden') {\n element.attr('aria-hidden', 'true');\n return;\n } else if (containerCtrl.input) {\n if (containerCtrl.input[0].contains(element[0])) {\n return;\n } else {\n throw new Error(\" can only have *one* ,

They are useful for displaying\n * additional options within the context of an action.\n *\n * Every `md-menu` must specify exactly two child elements. The first element is what is\n * left in the DOM and is used to open the menu. This element is called the trigger element.\n * The trigger element's scope has access to `$mdMenu.open($event)`\n * which it may call to open the menu. By passing $event as argument, the\n * corresponding event is stopped from propagating up the DOM-tree. Similarly, `$mdMenu.close()`\n * can be used to close the menu.\n *\n * The second element is the `md-menu-content` element which represents the\n * contents of the menu when it is open. Typically this will contain `md-menu-item`s,\n * but you can do custom content as well.\n *\n * \n * \n * \n * \n * \n * \n * \n *

Do Something

\n * \n * \n * \n\n * ## Sizing Menus\n *\n * The width of the menu when it is open may be specified by specifying a `width`\n * attribute on the `md-menu-content` element.\n * See the [Material Design Spec](https://material.io/archive/guidelines/components/menus.html#menus-simple-menus)\n * for more information.\n *\n * ## Menu Density\n *\n * You can use dense menus by adding the `md-dense` class to the `md-menu-content` element.\n * This reduces the height of menu items, their top and bottom padding, and default font size.\n * Without the `md-dense` class, we use the \"mobile\" height of `48px`. With the `md-dense` class,\n * we use the \"desktop\" height of `32px`. We do not support the \"dense desktop\" option in the spec,\n * which uses a height of `24px`, at this time.\n * See the [Menu Specs](https://material.io/archive/guidelines/components/menus.html#menus-specs)\n * section of the Material Design Spec for more information.\n *\n * ## Aligning Menus\n *\n * When a menu opens, it is important that the content aligns with the trigger element.\n * Failure to align menus can result in jarring experiences for users as content\n * suddenly shifts. To help with this, `md-menu` provides several APIs to help\n * with alignment.\n *\n * ### Target Mode\n *\n * By default, `md-menu` will attempt to align the `md-menu-content` by aligning\n * designated child elements in both the trigger and the menu content.\n *\n * To specify the alignment element in the `trigger` you can use the `md-menu-origin`\n * attribute on a child element. If no `md-menu-origin` is specified, the `md-menu`\n * will be used as the origin element.\n *\n * Similarly, the `md-menu-content` may specify a `md-menu-align-target` for a\n * `md-menu-item` to specify the node that it should try and align with.\n *\n * In this example code, we specify an icon to be our origin element, and an\n * icon in our menu content to be our alignment target. This ensures that both\n * icons are aligned when the menu opens.\n *\n * \n * \n * \n * \n * \n * \n * \n * \n * \n * Do Something\n * \n * \n * \n * \n * \n *\n * ### Position Mode\n *\n * We can specify the origin of the menu by using the `md-position-mode` attribute.\n * This attribute allows specifying the positioning by the `x` and `y` axes.\n *\n * The default mode is `target target`. This mode uses the left and top edges of the origin element\n * to position the menu in LTR layouts. The `x` axis modes will adjust when in RTL layouts.\n *\n * Sometimes you want to specify alignment from the right side of a origin element. For example,\n * if we have a menu on the right side a toolbar, we may want to right align our menu content.\n * We can use `target-right target` to specify a right-oriented alignment target.\n * There is a working example of this in the Menu Position Modes demo.\n *\n * #### Horizontal Positioning Options\n * - `target`\n * - `target-left`\n * - `target-right`\n * - `cascade`\n * - `right`\n * - `left`\n *\n * #### Vertical Positioning Options\n * - `target`\n * - `cascade`\n * - `bottom`\n *\n * ### Menu Offsets\n *\n * It is sometimes unavoidable to need to have a deeper level of control for\n * the positioning of a menu to ensure perfect alignment. `md-menu` provides\n * the `md-offset` attribute to allow pixel-level specificity when adjusting\n * menu positioning.\n *\n * This offset is provided in the format of `x y` or `n` where `n` will be used\n * in both the `x` and `y` axis.\n * For example, to move a menu by `2px` down from the top, we can use:\n *\n * \n * \n * \n * \n * \n *\n * Specifying `md-offset=\"2 2\"` would shift the menu two pixels down and two pixels to the right.\n *\n * ### Auto Focus\n * By default, when a menu opens, `md-menu` focuses the first button in the menu content.\n *\n * Sometimes you would like to focus another menu item instead of the first.
\n * This can be done by applying the `md-autofocus` directive on the given element.\n *\n * \n * \n * \n * Auto Focus\n * \n * \n * \n *\n *\n * ### Preventing close\n *\n * Sometimes you would like to be able to click on a menu item without having the menu\n * close. To do this, AngularJS Material exposes the `md-prevent-menu-close` attribute which\n * can be added to a button inside a menu to stop the menu from automatically closing.\n * You can then close the menu either by using `$mdMenu.close()` in the template,\n * or programmatically by injecting `$mdMenu` and calling `$mdMenu.hide()`.\n *\n * \n * \n * \n * \n * \n * Do Something\n * \n * \n * \n * \n *\n * @usage\n * \n * \n * \n * \n * \n * \n *

Do Something

\n * \n * \n * \n *\n * @param {string=} md-position-mode Specify pre-defined position modes for the `x` and `y` axes.\n * The default modes are `target target`. This positions the origin of the menu using the left and top edges\n * of the origin element in LTR layouts.
\n * #### Valid modes for horizontal positioning\n * - `target`\n * - `target-left`\n * - `target-right`\n * - `cascade`\n * - `right`\n * - `left`
\n * #### Valid modes for vertical positioning\n * - `target`\n * - `cascade`\n * - `bottom`\n * @param {string=} md-offset An offset to apply to the dropdown on opening, after positioning.\n * Defined as `x` and `y` pixel offset values in the form of `x y`.
\n * The default value is `0 0`.\n */\nMenuDirective.$inject = [\"$mdUtil\"];\nangular\n .module('material.components.menu')\n .directive('mdMenu', MenuDirective);\n\n/**\n * @ngInject\n */\nfunction MenuDirective($mdUtil) {\n var INVALID_PREFIX = 'Invalid HTML for md-menu: ';\n return {\n restrict: 'E',\n require: ['mdMenu', '?^mdMenuBar'],\n controller: 'mdMenuCtrl', // empty function to be built by link\n scope: true,\n compile: compile\n };\n\n function compile(templateElement) {\n templateElement.addClass('md-menu');\n\n var triggerEl = templateElement.children()[0];\n var prefixer = $mdUtil.prefixer();\n\n if (!prefixer.hasAttribute(triggerEl, 'ng-click')) {\n triggerEl = triggerEl\n .querySelector(prefixer.buildSelector(['ng-click', 'ng-mouseenter'])) || triggerEl;\n }\n\n var isButtonTrigger = triggerEl.nodeName === 'MD-BUTTON' || triggerEl.nodeName === 'BUTTON';\n\n if (triggerEl && isButtonTrigger && !triggerEl.hasAttribute('type')) {\n triggerEl.setAttribute('type', 'button');\n }\n\n if (!triggerEl) {\n throw Error(INVALID_PREFIX + 'Expected the menu to have a trigger element.');\n }\n\n if (templateElement.children().length !== 2) {\n throw Error(INVALID_PREFIX + 'Expected two children elements.

\n * \n * \n * \n * \n * \n * \n * \n *\n * ## Menu Bar Controls\n *\n * You may place `md-menu-item`s that function as controls within menu bars.\n * There are two modes that are exposed via the `type` attribute of the `md-menu-item`.\n * `type=\"checkbox\"` will function as a boolean control for the `ng-model` attribute of the\n * `md-menu-item`. `type=\"radio\"` will function like a radio button, setting the `ngModel`\n * to the `string` value of the `value` attribute. If you need non-string values, you can use\n * `ng-value` to provide an expression (this is similar to how angular's native `input[type=radio]`\n * works.\n *\n * If you want either to disable closing the opened menu when clicked, you can add the\n * `md-prevent-menu-close` attribute to the `md-menu-item`. The attribute will be forwarded to the\n * `button` element that is generated.\n *\n * \n * \n * \n * \n * \n * \n * Allow changes\n * \n * \n * Mode 1\n * Mode 2\n * Mode 3\n * \n * \n * \n * \n *\n *\n * ### Nesting Menus\n *\n * Menus may be nested within menu bars. This is commonly called cascading menus.\n * To nest a menu place the nested menu inside the content of the `md-menu-item`.\n * \n * \n * \n * ' +\n * '

Any\n * fields passed in through locals or resolve will be bound to the\n * controller.\n * - `controllerAs` - `{string=}`: An alias to assign the controller to on\n * the scope.\n * - `bindToController` - `{boolean=}`: Binds locals to the controller\n * instead of passing them in. Defaults to true, as this is a best\n * practice.\n * - `locals` - `{Object=}`: An object containing key/value pairs. The keys\n * will be used as names of values to inject into the controller. For\n * example, `locals: {three: 3}` would inject `three` into the controller,\n * with the value 3. 'mdPanelRef' is a reserved key, and will always\n * be set to the created `MdPanelRef` instance.\n * - `resolve` - `{Object=}`: Similar to locals, except it takes promises as\n * values.

The currently supported closeReasons\n * can be found in the `MdPanelRef.closeReasons` enum. These are by default\n * passed along by the panel.\n * - `trapFocus` - `{boolean=}`: Whether focus should be trapped within the\n * panel. If `trapFocus` is true, the user will not be able to interact\n * with the rest of the page until the panel is dismissed. Defaults to\n * false.\n * - `focusOnOpen` - `{boolean=}`: An option to override focus behavior on\n * open. Only disable if focusing some other way, as focus management is\n * required for panels to be accessible. Defaults to true.\n * - `fullscreen` - `{boolean=}`: Whether the panel should be full screen.\n * Applies the class `._md-panel-fullscreen` to the panel on open. Defaults\n * to false.\n * - `animation` - `{MdPanelAnimation=}`: An MdPanelAnimation object that\n * specifies the animation of the panel. For more information, see\n * `MdPanelAnimation`.\n * - `hasBackdrop` - `{boolean=}`: Whether there should be an opaque backdrop\n * behind the panel. Defaults to false.\n * - `disableParentScroll` - `{boolean=}`: Whether the user can scroll the\n * page behind the panel. Defaults to false.\n * - `onDomAdded` - `{function=}`: Callback function used to announce when\n * the panel is added to the DOM.\n * - `onOpenComplete` - `{function=}`: Callback function used to announce\n * when the open() action is finished.\n * - `onRemoving` - `{function=}`: Callback function used to announce the\n * close/hide() action is starting.\n * - `onDomRemoved` - `{function=}`: Callback function used to announce when\n * the panel is removed from the DOM.\n * - `origin` - `{(string|!JQLite|!Element)=}`: The element to focus\n * on when the panel closes.

Consider the following example:\n * \n * angular.controller('MyCtrl', function($scope) {\n * $scope.users = [\n * { id: 1, name: 'Bob' },\n * { id: 2, name: 'Alice' },\n * { id: 3, name: 'Steve' }\n * ];\n * $scope.selectedUser = { id: 1, name: 'Bob' };\n * });\n * \n * \n *

\n * \n * {{ user.name }}\n * \n *

\n * \n *\n * At first one might expect that the select should be populated with \"Bob\" as the selected user.\n * However, this is not true. To determine whether something is selected,\n * `ngModelController` is looking at whether `$scope.selectedUser == (any user in $scope.users);`;\n *\n * Javascript's `==` operator does not check for deep equality (ie. that all properties\n * on the object are the same), but instead whether the objects are *the same object in memory*.\n * In this case, we have two instances of identical objects, but they exist in memory as unique\n * entities. Because of this, the select will have no value populated for a selected user.\n *\n * To get around this, `ngModelController` provides a `track by` option that allows us to specify a\n * different expression which will be used for the equality operator. As such, we can update our\n * `html` to make use of this by specifying the `ng-model-options=\"{trackBy: '$value.id'}\"` on the\n * `md-select` element. This converts our equality expression to be\n * `$scope.selectedUser.id == (any id in $scope.users.map(function(u) { return u.id; }));`\n * which results in Bob being selected as desired.\n *\n * **Note:** We do not support AngularJS's `track by` syntax. For instance\n * `ng-options=\"user in users track by user.id\"` will not work with `md-select`.\n *\n * Working HTML:\n * \n *

It handles this\n * case a more natively and more performantly.</blockquote>\n *\n * **Tabs with internal views** are the traditional usage where each tab has associated view\n * content and the view switching is managed internally by the Tabs component.\n *\n * **Tabs with external view content** is often useful when content associated with each tab is\n * independently managed and data-binding notifications announce tab selection changes.\n *\n * Additional features include:\n *\n * *  Content can include any markup.\n * *  If a tab is disabled while active/selected, then the next tab will be auto-selected.\n *\n * ### Theming\n *\n * By default, tabs use your app's accent color for the selected tab's text and ink bar.\n *\n * You can use the theming classes to change the color of the `md-tabs` background:\n * * Applying `class=\"md-primary\"` will use your app's primary color for the background, your\n *   accent color for the ink bar, and your primary palette's contrast color for the text of the\n *   selected tab.\n *   * When using the `md-primary` class, you can add the `md-no-ink-bar-color` class to make the\n *     ink bar use your theme's primary contrast color instead of the accent color.\n * * Applying `class=\"md-accent\"` will use your app's accent color for the background and your\n *   accent palette's contrast color for the text and ink bar of the selected tab.\n * * Applying `class=\"md-warn\"` will use your app's warn color for the background and your\n *   warn palette's contrast color for the text and ink bar of the selected tab.\n *\n * ### Explanation of tab stretching\n *\n * Initially, tabs will have an inherent size.  This size will either be defined by how much space\n * is needed to accommodate their text or set by the user through CSS.\n * Calculations will be based on this size.\n *\n * On mobile devices, tabs will be expanded to fill the available horizontal space.\n * When this happens, all tabs will become the same size.\n *\n * On desktops, by default, stretching will never occur.\n *\n * This default behavior can be overridden through the `md-stretch-tabs` attribute.\n * Here is a table showing when stretching will occur:\n *\n * `md-stretch-tabs` | mobile    | desktop\n * ------------------|-----------|--------\n * `auto`            | stretched | ---\n * `always`          | stretched | stretched\n * `never`           | ---       | ---\n *\n * @param {number=} md-selected Index of the active/selected tab.\n * @param {expression=} md-no-ink-bar If `true` or no value, disables the selection ink bar.\n * @param {string=} md-align-tabs Attribute to indicate position of tab buttons: `bottom` or `top`;\n *  Default is `top`.\n * @param {string=} md-stretch-tabs Attribute to indicate whether or not to stretch tabs: `auto`,\n *  `always`, or `never`; Default is `auto`.\n * @param {expression=} md-dynamic-height If `true` or no value, the tab wrapper will resize based\n *  on the contents of the selected tab.\n * @param {boolean=} md-border-bottom If the attribute is present, shows a solid `1px` border\n *  between the tabs and their content.\n * @param {boolean=} md-center-tabs If the attribute is present, tabs will be centered provided\n *  there is no need for pagination.\n * @param {boolean=} md-no-pagination If the attribute is present, pagination will remain off.\n * @param {expression=} md-swipe-content When enabled, swipe gestures will be enabled for the content\n *  area to allow swiping between tabs.\n * @param {boolean=} md-enable-disconnect When enabled, scopes will be disconnected for tabs that\n *  are not being displayed. This provides a performance boost, but may also cause unexpected\n *  issues. It is not recommended for most users.\n * @param {boolean=} md-autoselect If the attribute is present, any tabs added after the initial\n *  load will be automatically selected.\n * @param {boolean=} md-no-select-click When true, click events will not be fired when the value of\n *  `md-active` on an `md-tab` changes. This is useful when using tabs with UI-Router's child\n *  states, as triggering a click event in that case can cause an extra tab change to occur.\n * @param {string=} md-navigation-hint Attribute to override the default `tablist` navigation hint\n *  that screen readers will announce to provide instructions for navigating between tabs. This is\n *  desirable when you want the hint to be in a different language. Default is \"Use the left and\n *  right arrow keys to navigate between tabs\".\n *\n * @usage\n * <hljs lang=\"html\">\n * <md-tabs md-selected=\"selectedIndex\">\n *   <img

@description\n * `$mdToast` is a service to build a toast notification on any position\n * on the screen with an optional duration, and provides a simple promise API.\n *\n * The toast will be always positioned at the `bottom`, when the screen size is\n * between `600px` and `959px` (`sm` breakpoint)\n *\n * ## Restrictions on custom toasts\n * - The toast's template must have an outer `<md-toast>` element.\n * - For a toast action, use element with class `md-action`.\n * - Add the class `md-capsule` for curved corners.\n *\n * ### Custom Presets\n * Developers are also able to create their own preset, which can be easily used without repeating\n * their options each time.\n *\n * <hljs lang=\"js\">\n *   $mdToastProvider.addPreset('testPreset', {\n *     options: function() {\n *       return {\n *         template:\n *           '<md-toast>' +\n *             '<div class=\"md-toast-content\">' +\n *               'This is a custom preset' +\n *             '</div>' +\n

can easily access it.\n *\n * <hljs lang=\"js\">\n *   $mdToast.show(\n *     $mdToast.testPreset()\n *   );\n * </hljs>\n *\n * ## Parent container notes\n *\n * The toast is positioned using absolute positioning relative to its first non-static parent\n * container. Thus, if the requested parent container uses static positioning, we will temporarily\n * set its positioning to `relative` while the toast is visible and reset it when the toast is\n * hidden.\n *\n * Because of this, it is usually best to ensure that the parent container has a fixed height and\n * prevents scrolling by setting the `overflow: hidden;` style. Since the position is based off of\n * the parent's height, the toast may be mispositioned if you allow the parent to scroll.\n *\n * You can, however, have a scrollable element inside of the container; just make sure the\n * container itself does not scroll.\n *\n * <hljs lang=\"html\">\n * <div layout-fill id=\"toast-container\">\n *   <md-content>\n *     I can have lots of content and scroll!\n *   </md-content>\n * </div>\n * </hljs>\n *\n * @usage\n * <hljs lang=\"html\">\n * <div ng-controller=\"MyController\">\n *   <md-button ng-click=\"openToast()\">\n *     Open a Toast!\n *   </md-button>\n * </div>\n * </hljs>\n *\n * <hljs lang=\"js\">\n * var app = angular.module('app', ['ngMaterial']);\n * app.controller('MyController', function($scope, $mdToast) {\n *   $scope.openToast = function($event) {\n *     $mdToast.show($mdToast.simple().textContent('Hello!'));\n *     // Could also do $mdToast.showSimple('Hello');\n *   };\n * });\n * </hljs>\n */\n\n/**\n * @ngdoc method\n * @name $mdToast#showSimple\n *\n * @param {string} message The message to display inside the toast\n * @description\n * Convenience method which builds and shows a simple toast.\n *\n * @returns {promise} A promise that can be resolved with `$mdToast.hide()`.\n */\n\n/**\n * @ngdoc method\n * @name $mdToast#simple\n *\n * @description\n * Builds a preconfigured toast.\n *\n * @returns {obj} a `$mdToastPreset` with the following chainable configuration methods.\n *\n * _**Note:** These configuration methods are provided in addition to the methods provided by\n * the `build()` and `show()` methods below._\n *\n * <table class=\"md-api-table methods\">\n *    <thead>\n *      <tr>\n *        <th>Method</th>\n *        <th>Description</th>\n *      </tr>\n *    </thead>\n *    <tbody>\n *      <tr>\n *        <td>`.textContent(string)`</td>\n *        <td>Sets the toast content to the specified string</td>\n *      </tr>\n *      <tr>\n *        <td>`.action(string)`</td>\n *        <td>\n *          Adds an action button. <br/>\n *          If clicked, the promise (returned from `show()`) will resolve with the value `'ok'`;\n *          otherwise, it is resolved with `true` after a `hideDelay` timeout.\n *        </td>\n *      </tr>\n *      <tr>\n *        <td>`.actionKey(string)`</td>\n *        <td>\n *          Adds a hotkey for the action button to the page. <br/>\n *          If the `actionKey` and `Control` key are pressed, the toast's action will be triggered.\n *        </td>\n *      </tr>\n *      <tr>\n *        <td>`.actionHint(string)`</td>\n *        <td>\n *          Text that a screen reader will announce to let the user know how to activate the\n *          action. <br>\n *          If an `actionKey` is defined, this defaults to:\n *          'Press Control-\"`actionKey`\" to ' followed by the `action`.\n *        </td>\n *      </tr>\n *      <tr>\n *        <td>`.dismissHint(string)`</td>\n *        <td>\n *          Text that a screen reader will announce to let the user know how to dismiss the toast.\n *          <br>Defaults to: \"Press Escape to dismiss.\"\n *        </td>\n *      </tr>\n *      <tr>\n *        <td>`.highlightAction(boolean)`</td>\n *        <td>\n *          Whether or not the action button will have an additional highlight class.<br/>\n *          By default the `accent` color will be applied to the action button.\n *        </td>\n *      </tr>\n *      <tr>\n *        <td>`.highlightClass(string)`</td>\n *        <td>\n *          If set, the given class will be applied to the highlighted action button.<br/>\n *          This allows you to specify the highlight color easily.

This provides smooth and performant scrolling through very large lists of elements.\n *\n * Virtual repeat is a limited substitute for `ng-repeat` that renders only\n * enough DOM nodes to fill the container, recycling them as the user scrolls.\n *\n * ### Notes\n *\n * - Arrays are supported for iteration by default.\n * - An object can used use if `md-on-demand` is specified and the object implements the interface\n *   described in the `md-on-demand` <a ng-href=\"#attributes\">documentation</a>.\n * - `trackBy`, `as` alias, and `(key, value)` syntax from `ng-repeat` are not supported.\n *\n * ### On-Demand Async Item Loading\n *\n * When using the `md-on-demand` attribute and loading some asynchronous data,\n * the `getItemAtIndex` function will mostly return nothing.\n *\n * <hljs lang=\"js\">\n *   DynamicItems.prototype.getItemAtIndex = function(index) {\n *     if (this.pages[index]) {\n *       return this.pages[index];\n *     } else {\n *       // This is an asynchronous action and does not return any value.\n *       this.loadPage(index);\n *     }\n *   };\n * </hljs>\n *\n * This means that the Virtual Repeat will not have any value for the given index.<br/>\n * After the data loading completes, the user expects the Virtual Repeat to recognize the change.\n *\n * To make sure that the Virtual Repeat properly detects any change, you need to run the operation\n * in another digest.\n *\n * <hljs lang=\"js\">\n *   DynamicItems.prototype.loadPage = function(index) {\n *     var self = this;\n *\n *     // Trigger a new digest by using $timeout\n *     $timeout(function() {\n *       self.pages[index] = Data;\n *     });\n *   };\n * </hljs>\n *\n * > <b>Note:</b> Please also review the\n *   <a ng-href=\"api/directive/mdVirtualRepeatContainer\">VirtualRepeatContainer</a> documentation\n *   for more information.\n *\n * @usage\n * <hljs lang=\"html\">\n * <md-virtual-repeat-container>\n *   <div md-virtual-repeat=\"i in items\">Hello {{i}}!</div>\n * </md-virtual-repeat-container>\n *\n * <md-virtual-repeat-container md-orient-horizontal>\n *   <div md-virtual-repeat=\"i in items\" md-item-size=\"20\">Hello {{i}}!</div>\n * </md-virtual-repeat-container>\n * </hljs>\n *\n * @param {expression=} md-extra-name Evaluates to an additional name to which the current iterated\n *   item can be assigned on the repeated scope (needed for use in `md-autocomplete`).\n * @param {number=} md-item-size Optional height or width of the repeated elements (which **must be\n *   identical for each element**). Virtual repeat will attempt to read the size from the DOM,\n *   if missing, but it still assumes that all repeated nodes have the **same height**\n *   (when scrolling vertically) or **same width** (when scrolling horizontally).\n * @param {boolean=} md-on-demand When present, treats the `md-virtual-repeat` argument as an object\n *   that can fetch rows rather than an array.\n *\n *   **NOTE:** This object **must** implement the following interface with two methods:\n *\n *   - `getItemAtIndex` - `{function(index): Object}`: The item at that `index` or `null` if it is\n *     not yet loaded (it should start downloading the item in that case).\n *   - `getLength` - `{function(): number}`: The data length to which the repeater container\n *     should be sized. Ideally, when the count is known, this method should return it.\n *     Otherwise, return a higher number than the currently loaded items to produce an\n *     infinite-scroll behavior.\n */\nfunction VirtualRepeatDirective($parse) {\n  return {\n    controller: VirtualRepeatController,\n    priority: 1000,\n    require: ['mdVirtualRepeat', '^^mdVirtualRepeatContainer'],\n    restrict: 'A',\n    terminal: true,\n    transclude: 'element',\n    compile: function VirtualRepeatCompile($element, $attrs) {\n      var expression = $attrs.mdVirtualRepeat;\n      var match = expression.match(/^\\s*([\\s\\S]+?)\\s+in\\s+([\\s\\S]+?)\\s*$/);\n      var repeatName = match[1];\n      var repeatListExpression = $parse(match[2]);\n      var extraName = $attrs.mdExtraName && $parse($attrs.mdExtraName);\n\n      return function VirtualRepeatLink($scope, $element, $attrs, ctrl, $transclude) {\n        ctrl[0].link_(ctrl[1], $transclude, repeatName, repeatListExpression, extraName);\n      };\n    }\n  };\n}\n\n\n/** @ngInject */\nfunction VirtualRepeatController($scope, $element, $attrs, $browser, $document, $rootScope,\n    $$rAF, $mdUtil) {\n  this.$scope = $scope;\n  this.$element = $element;\n  this.$attrs = $attrs;\n  this.$browser = $browser;\n  this.$document = $document;\n  this.$mdUtil = $mdUtil;\n  this.$rootScope = $rootScope;\n  this.$$rAF = $$rAF;\n\n  /** @type {boolean} Whether we are in on-demand mode. */\n  this.onDemand = $mdUtil.parseAttributeBoolean($attrs.mdOnDemand);\n  /** @type {!Function} Backup reference to $browser.$$checkUrlChange */\n  this.browserCheckUrlChange = $browser.$$checkUrlChange;\n  /** @type {number} Most recent starting repeat index (based on scroll offset) */\n  this.newStartIndex = 0;\n  /** @type {number} Most recent ending repeat index (based on scroll offset) */\n  this.newEndIndex = 0;\n  /** @type {number} Most recent end visible index (based on scroll offset) */\n  this.newVisibleEnd = 0;\n  /** @type {number} Previous starting repeat index (based on scroll offset) */\n  this.startIndex = 0;\n  /** @type {number} Previous ending repeat index (based on scroll offset) */\n  this.endIndex = 0;\n  /** @type {?number} Height/width of repeated elements. */\n  this.itemSize = $scope.$eval($attrs.mdItemSize) || null;\n\n  /** @type {boolean} Whether this is the first time that items are rendered. */\n  this.isFirstRender = true;\n\n  /**\n   * @private {boolean} Whether the items in the list are already being updated.

* @ngdoc module\n * @name ngMessages\n * @description\n *\n * The `ngMessages` module provides enhanced support for displaying messages within templates\n * (typically within forms or when rendering message objects that return key/value data).\n * Instead of relying on JavaScript code and/or complex ng-if statements within your form template to\n * show and hide error messages specific to the state of an input field, the `ngMessages` and\n * `ngMessage` directives are designed to handle the complexity, inheritance and priority\n * sequencing based on the order of how the messages are defined in the template.\n *\n * Currently, the ngMessages module only contains the code for the `ngMessages`, `ngMessagesInclude`\n * `ngMessage`, `ngMessageExp` and `ngMessageDefault` directives.\n *\n * ## Usage\n * The `ngMessages` directive allows keys in a key/value collection to be associated with a child element\n * (or 'message') that will show or hide based on the truthiness of that key's value in the collection. A common use\n * case for `ngMessages` is to display error messages for inputs using the `$error` object exposed by the\n * {@link ngModel ngModel} directive.\n *\n * The child elements of the `ngMessages` directive are matched to the collection keys by a `ngMessage` or\n * `ngMessageExp` directive. The value of these attributes must match a key in the collection that is provided by\n * the `ngMessages` directive.\n *\n * Consider the following example, which illustrates a typical use case of `ngMessages`. Within the form `myForm` we\n * have a text input named `myField` which is bound to the scope variable `field` using the {@link ngModel ngModel}\n * directive.\n *\n * The `myField` field is a required input of type `email` with a maximum length of 15 characters.\n *\n * ```html\n * <form name=\"myForm\">\n *   <label>\n *     Enter text:\n *     <input type=\"email\" ng-model=\"field\" name=\"myField\" required maxlength=\"15\" />\n *   </label>\n *   <div ng-messages=\"myForm.myField.$error\" role=\"alert\">\n *     <div ng-message=\"required\">Please enter a value for this field.</div>\n *     <div ng-message=\"email\">This field must be a valid email address.</div>\n *     <div ng-message=\"maxlength\">This field can be at most 15 characters long.</div>\n *   </div>\n * </form>\n * ```\n *\n * In order to show error messages corresponding to `myField` we first create an element with an `ngMessages` attribute\n * set to the `$error` object owned by the `myField` input in our `myForm` form.\n *\n * Within this element we then create separate elements for each of the possible errors that `myField` could have.\n * The `ngMessage` attribute is used to declare which element(s) will appear for which error - for example,\n * setting `ng-message=\"required\"` specifies that this particular element should be displayed when there\n * is no value present for the required field `myField` (because the key `required` will be `true` in the object\n * `myForm.myField.$error`).\n *\n * ### Message order\n *\n * By default, `ngMessages` will only display one message for a particular key/value collection at any time. If more\n * than one message (or error) key is currently true, then which message is shown is determined by the order of messages\n * in the HTML template code (messages declared first are prioritised). This mechanism means the developer does not have\n * to prioritize messages using custom JavaScript code.\n *\n * Given the following error object for our example (which informs us that the field `myField` currently has both the\n * `required` and `email` errors):\n *\n * ```javascript\n * \n * myField.$error = { required : true, email: true, maxlength: false };\n * ```\n * The `required` message will be displayed to the user since it appears before the `email` message in the DOM.\n * Once the user types a single character, the `required` message will disappear (since the field now has a value)\n * but the `email` message will be visible because it is still applicable.\n *\n * ### Displaying multiple messages at the same time\n *\n * While `ngMessages` will by default only display one error element at a time, the `ng-messages-multiple` attribute can\n * be applied to the `ngMessages` container element to cause it to display all applicable error messages at once:\n *\n * ```html\n * \n * <div ng-messages=\"myForm.myField.$error\" ng-messages-multiple>...</div>\n *\n * \n * <ng-messages for=\"myForm.myField.$error\" multiple>...</ng-messages>\n * ```\n *\n * ## Reusing and Overriding Messages\n * In addition to prioritization, ngMessages also allows for including messages from a remote or an inline\n * template. This allows for generic collection of messages to be reused across multiple parts of an\n * application.\n *\n * ```html\n * <script type=\"text/ng-template\" id=\"error-messages\">\n *   <div ng-message=\"required\">This field is required</div>\n *   <div ng-message=\"minlength\">This field is too short</div>\n * </script>\n *\n * <div ng-messages=\"myForm.myField.$error\" role=\"alert\">\n *   <div ng-messages-include=\"error-messages\"></div>\n * </div>\n * ```\n *\n * However, including generic messages may not be useful enough to match all input fields, therefore,\n * `ngMessages` provides the ability to override messages defined in the remote template by redefining\n * them within the directive container.\n *\n * ```html\n * \n * <script type=\"text/ng-template\" id=\"my-custom-messages\">\n *   <div ng-message=\"required\">This field is required</div>\n *   <div ng-message=\"minlength\">This field is too short</div>\n * </script>\n *\n * <form name=\"myForm\">\n *   <label>\n *     Email address\n *     <input type=\"email\"\n *            id=\"email\"\n *            name=\"myEmail\"\n *            ng-model=\"email\"\n *            minlength=\"5\"\n *            required />\n *   </label>\n *   \n *   <div ng-messages=\"myForm.myEmail.$error\" role=\"alert\">\n *     \n *     <div ng-message=\"required\">You did not enter your email address</div>\n *\n *     \n *     <div ng-message=\"email\">Your email address is invalid</div>\n *\n *     \n *     <div ng-messages-include=\"my-custom-messages\"></div>\n *   </div>\n * </form>\n * ```\n *\n * In the example HTML code above the message that is set on required will override the corresponding\n * required message defined within the remote template. Therefore, with particular input fields (such\n * email addresses, date fields, autocomplete inputs, etc...), specialized error messages can be applied\n * while more generic messages can be used to handle other, more general input errors.\n *\n * ## Dynamic Messaging\n * ngMessages also supports using expressions to dynamically change key values. Using arrays and\n * repeaters to list messages is also supported. This means that the code below will be able to\n * fully adapt itself and display the appropriate message when any of the expression data changes:\n *\n * ```html\n * <form name=\"myForm\">\n *   <label>\n *     Email address\n *     <input type=\"email\"\n *            name=\"myEmail\"\n *            ng-model=\"email\"\n *            minlength=\"5\"\n *            required />\n *   </label>\n *   <div ng-messages=\"myForm.myEmail.$error\" role=\"alert\">\n *     <div ng-message=\"required\">You did not enter your email address</div>\n *     <div ng-repeat=\"errorMessage in errorMessages\">\n *       \n *       <div ng-message-exp=\"errorMessage.type\">{{ errorMessage.text }}</div>\n *     </div>\n *   </div>\n * </form>\n * ```\n *\n * The `errorMessage.type` expression can be a string value or it can be an array so\n * that multiple errors can be associated with a single error message:\n *\n * ```html\n *   <label>\n *     Email address\n *     <input type=\"email\"\n *            ng-model=\"data.email\"\n *            name=\"myEmail\"\n *            ng-minlength=\"5\"\n *            ng-maxlength=\"100\"\n *            required />\n *   </label>\n *   <div ng-messages=\"myForm.myEmail.$error\" role=\"alert\">\n *     <div ng-message-exp=\"'required'\">You did not enter your email address</div>\n *     <div ng-message-exp=\"['minlength', 'maxlength']\">\n *       Your email must be between 5 and 100 characters long\n *     </div>\n *   </div>\n * ```\n *\n * Feel free to use other structural directives such as ng-if and ng-switch to further control\n * what messages are active and when. Be careful, if you place ng-message on the same element\n * as these structural directives, AngularJS may not be able to determine if a message is active\n * or not. Therefore it is best to place the ng-message on a child element of the structural\n * directive.\n *\n * ```html\n * <div ng-messages=\"myForm.myEmail.$error\" role=\"alert\">\n *   <div ng-if=\"showRequiredError\">\n *     <div ng-message=\"required\">Please enter something</div>\n *   </div>\n * </div>\n * ```\n *\n * ## Animations\n * If the `ngAnimate` module is active within the application then the `ngMessages`, `ngMessage` and\n * `ngMessageExp` directives will trigger animations whenever any messages are added and removed from\n * the DOM by the `ngMessages` directive.\n *\n * Whenever the `ngMessages` directive contains one or more visible messages then the `.ng-active` CSS\n * class will be added to the element. The `.ng-inactive` CSS class will be applied when there are no\n * messages present. Therefore, CSS transitions and keyframes as well as JavaScript animations can\n * hook into the animations whenever these classes are added/removed.\n *\n * Let's say that our HTML code for our messages container looks like so:\n *\n * ```html\n * <div ng-messages=\"myMessages\" class=\"my-messages\" role=\"alert\">\n *   <div ng-message=\"alert\" class=\"some-message\">...</div>\n *   <div ng-message=\"fail\" class=\"some-message\">...</div>\n * </div>\n * ```\n *\n * Then the CSS animation code for the message container looks like so:\n *\n * ```css\n * .my-messages {\n *   transition:1s linear all;\n * }\n * .my-messages.ng-active {\n *   // messages are visible\n * }\n * .my-messages.ng-inactive {\n *   // messages are hidden\n * }\n * ```\n *\n * Whenever an inner message is attached (becomes visible) or removed (becomes hidden) then the enter\n * and leave animation is triggered for each particular element bound to the `ngMessage` directive.\n *\n * Therefore, the CSS code for the inner messages looks like so:\n *\n * ```css\n * .some-message {\n *   transition:1s linear all;\n * }\n *\n * .some-message.ng-enter {}\n * .some-message.ng-enter.ng-enter-active {}\n *\n * .some-message.ng-leave {}\n * .some-message.ng-leave.ng-leave-active {}\n * ```\n *\n * {@link ngAnimate See the ngAnimate docs} to learn how to use JavaScript animations or to learn\n * more about ngAnimate.\n *\n * ## Displaying a default message\n * If the ngMessages renders no inner ngMessage directive (i.e. when none of the truthy\n * keys are matched by a defined message), then it will render a default message\n * using the {@link ngMessageDefault} directive.\n * Note that matched messages will always take precedence over unmatched messages. That means\n * the default message will not be displayed when another message is matched. This is also\n * true for `ng-messages-multiple`.\n *\n * ```html\n * <div ng-messages=\"myForm.myField.$error\" role=\"alert\">\n *   <div ng-message=\"required\">This field is required</div>\n *   <div ng-message=\"minlength\">This field is too short</div>\n *   <div ng-message-default>This field has an input error</div>\n * </div>\n * ```\n *\n\n */\nangular.module('ngMessages', [], function initAngularHelpers() {\n  // Access helpers from AngularJS core.\n  // Do it inside a `config` block to ensure `window.angular` is available.\n  forEach = angular.forEach;\n  isArray = angular.isArray;\n  isString = angular.isString;\n  jqLite = angular.element;\n})\n  .info({ angularVersion: '1.8.2' })\n\n  /**\n   * @ngdoc directive\n   * @module ngMessages\n   * @name ngMessages\n   * @restrict AE\n   *\n   * @description\n   * `ngMessages` is a directive that is designed to show and hide messages based on the state\n   * of a key/value object that it listens on.

By default, only one message will be displayed\n   * at a time and this depends on the prioritization of the messages within the template. (This can\n   * be changed by using the `ng-messages-multiple` or `multiple` attribute on the directive container.)\n   *\n   * A remote template can also be used (With {@link ngMessagesInclude}) to

If you need this sequence to appear and not collapse then you\n *   can escape it with `/\\.`.\n *\n * @param {Object=} paramDefaults Default values for `url` parameters. These can be overridden in\n *   `actions` methods. If a parameter value is a function, it will be called every time\n *   a param value needs to be obtained for a request (unless the param was overridden).

If any of\n *     the parameter value is a function, it will be called every time when a param value needs to\n *     be obtained for a request (unless the param was overridden). The function will be passed the\n *     current data value as an argument.\n *   - **`url`** â {string} â Action specific `url` override. The url templating is supported just\n *     like for the resource-level urls.\n *   - **`isArray`** â {boolean=} â If true then the returned object for this action is an array,\n *     see `returns` section.\n *   - **`transformRequest`** â\n *     `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` â\n *     Transform function or an array of such functions. The transform function takes the http\n *     request body and headers and returns its transformed (typically serialized) version.\n *     By default, transformRequest will contain one function that checks if the request data is\n *     an object and serializes it using `angular.toJson`. To prevent this behavior, set\n *     `transformRequest` to an empty array: `transformRequest: []`\n *   - **`transformResponse`** â\n *     `{function(data, headersGetter, status)|Array.<function(data, headersGetter, status)>}` â\n *     Transform function or an array of such functions. The transform function takes the HTTP\n *     response body, headers and status and returns its transformed (typically deserialized)\n *     version.\n *     By default, transformResponse will contain one function that checks if the response looks\n *     like a JSON string and deserializes it using `angular.fromJson`. To prevent this behavior,\n *     set `transformResponse` to an empty array: `transformResponse: []`\n *   - **`cache`** â `{boolean|Cache}` â A boolean value or object created with\n *     {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.\n *     See {@link $http#caching $http Caching} for more information.\n *   - **`timeout`** â `{number}` â Timeout in milliseconds.<br />\n *     **Note:** In contrast to {@link ng.$http#usage $http.config}, {@link ng.$q promises} are\n *     **not** supported in `$resource`, because the same value would be used for multiple requests.\n *     If you are looking for a way to cancel requests, you should use the `cancellable` option.\n *   - **`cancellable`** â `{boolean}` â If true, the request made by a \"non-instance\" call will be\n *     cancelled (if not already completed) by calling `$cancelRequest()` on the call's return\n *     value. Calling `$cancelRequest()` for a non-cancellable or an already completed/cancelled\n *     request will have no effect.\n *   - **`withCredentials`** â `{boolean}` â Whether to set the `withCredentials` flag on the\n *     XHR object. See\n *     [XMLHttpRequest.withCredentials](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/withCredentials)\n *     for more information.\n *   - **`responseType`** â `{string}` â See\n *     [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/responseType).\n *   - **`interceptor`** â `{Object=}` â The interceptor object has four optional methods -\n *     `request`, `requestError`, `response`, and `responseError`. See\n *     {@link ng.$http#interceptors $http interceptors} for details. Note that\n *     `request`/`requestError` interceptors are applied before calling `$http`, thus before any\n *     global `$http` interceptors. Also, rejecting or throwing an error inside the `request`\n *     interceptor will result in calling the `responseError` interceptor.\n *     The resource instance or collection is available on the `resource` property of the\n *     `http response` object passed to `response`/`responseError` interceptors.\n *     Keep in mind that the associated promise will be resolved with the value returned by the\n *     response interceptors. Make sure you return an appropriate value and not the `response`\n *     object passed as input. For reference, the default `response` interceptor (which gets applied\n *     if you don't specify a custom one) returns `response.resource`.<br />\n *     See {@link ngResource.$resource#using-interceptors below} for an example of using\n *     interceptors in `$resource`.\n *   - **`hasBody`** â `{boolean}` â If true, then the request will have a body.\n *     If not specified, then only POST, PUT and PATCH requests will have a body. *\n * @param {Object} options Hash with custom settings that should extend the\n *   default `$resourceProvider` behavior.  The supported options are:\n *\n *   - **`stripTrailingSlashes`** â {boolean} â If true then the trailing\n *   slashes from any calculated URL will be stripped. (Defaults to true.)\n *   - **`cancellable`** â {boolean} â If true, the request made by a \"non-instance\" call will be\n *   cancelled (if not already completed) by calling `$cancelRequest()` on the call's return value.\n *   This can be overwritten per action. (Defaults to false.)\n *\n * @returns {Object} A resource \"class\" object with methods for the default set of resource actions\n *   optionally extended with custom `actions`. The default set contains these actions:\n *   ```js\n *   {\n *     'get':    {method: 'GET'},\n *     'save':   {method: 'POST'},\n *     'query':  {method: 'GET', isArray: true},\n *     'remove': {method: 'DELETE'},\n *     'delete': {method: 'DELETE'}\n *   }\n *   ```\n *\n *   Calling these methods invoke {@link ng.$http} with the specified http method, destination and\n *   parameters. When the data is returned from the server then the object is an instance of the\n *   resource class. The actions `save`, `remove` and `delete` are available on it as methods with\n *   the `$` prefix. This allows you to easily perform CRUD operations (create, read, update,\n *   delete) on server-side data like this:\n *   ```js\n *   var User = $resource('/user/:userId', {userId: '@id'});\n *   User.get({userId: 123}).$promise.then(function(user) {\n *     user.abc = true;\n *     user.$save();\n *   });\n *   ```\n *\n *   It is important to realize that invoking a `$resource` object method immediately returns an\n *   empty reference (object or array depending on `isArray`). Once the data is returned from the\n *   server the existing reference is populated with the actual data. This is a useful trick since\n *   usually the resource is assigned to a model which is then rendered by the view. Having an empty\n *   object results in no rendering, once the data arrives from the server then the object is\n *   populated with the data and the view automatically re-renders itself showing the new data. This\n *   means that in most cases one never has to write a callback function for the action methods.\n *\n *   The action methods on the class object or instance object can be invoked with the following\n *   parameters:\n *\n *   - \"class\" actions without a body: `Resource.action([parameters], [success], [error])`\n *   - \"class\" actions with a body: `Resource.action([parameters], postData, [success], [error])`\n *   - instance actions: `instance.$action([parameters], [success], [error])`\n *\n *\n *   When calling instance methods, the instance itself is used as the request body (if the action\n *   should have a body). By default, only actions using `POST`, `PUT` or `PATCH` have request\n *   bodies, but you can use the `hasBody` configuration option to specify whether an action\n *   should have a body or not (regardless of its HTTP method).\n *\n *\n *   Success callback is called with (value (Object|Array), responseHeaders (Function),\n *   status (number), statusText (string)) arguments, where `value` is the populated resource\n *   instance or collection object. The error callback is called with (httpResponse) argument.\n *\n *   Class actions return an empty instance (with the additional properties listed below).\n *   Instance actions return a promise for the operation.\n *\n *   The Resource instances and collections have these additional properties:\n *\n *   - `$promise`: The {@link ng.$q promise} of the original server interaction that created this\n *     instance or collection.\n *\n *     On success, the promise is resolved with the same resource instance or collection object,\n *     updated with data from server. This makes it easy to use in the\n *     {@link ngRoute.$routeProvider `resolve` section of `$routeProvider.when()`} to defer view\n *     rendering until the resource(s) are loaded.\n *\n *     On failure, the promise is rejected with the {@link ng.$http http response} object.\n *\n *     If an interceptor object was provided, the promise will instead be resolved with the value\n *     returned by the response interceptor (on success) or responceError interceptor (on failure).\n *\n *   - `$resolved`: `true` after first server interaction is completed (either with success or\n *      rejection), `false` before that. Knowing if the Resource has been resolved is useful in\n *      data-binding. If there is a response/responseError interceptor and it returns a promise,\n *      `$resolved` will wait for that too.\n *\n *   The Resource instances and collections have these additional methods:\n *\n *   - `$cancelRequest`: If there is a cancellable, pending request related to the instance or\n *      collection, calling this method will abort the request.\n *\n *   The Resource instances have these additional methods:\n *\n *   - `toJSON`: It returns a simple object without any of the extra properties added as part of\n *     the Resource API. This object can be serialized through {@link angular.toJson} safely\n *     without attaching AngularJS-specific fields. Notice that `JSON.stringify` (and\n *     `angular.toJson`) automatically use this method when serializing a Resource instance\n *     (see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#toJSON%28%29_behavior)).\n *\n * @example\n *\n * ### Basic usage\n *\n   ```js\n     // Define a CreditCard class\n     var CreditCard = $resource('/users/:userId/cards/:cardId',\n       {userId: 123, cardId: '@id'}, {\n         charge: {method: 'POST', params: {charge: true}}\n       });\n\n     // We can retrieve a collection from the server\n     var cards = CreditCard.query();\n         // GET: /users/123/cards\n         // server returns: [{id: 456, number: '1234', name: 'Smith'}]\n\n     // Wait for the request to complete\n     cards.$promise.then(function() {\n       var card = cards[0];\n\n       // Each item is an instance of CreditCard\n       expect(card instanceof CreditCard).toEqual(true);\n\n       // Non-GET methods are mapped onto the instances\n       card.name = 'J. Smith';\n       card.$save();\n           // POST: /users/123/cards/456 {id: 456, number: '1234', name: 'J. Smith'}\n           // server returns: {id: 456, number: '1234', name: 'J. Smith'}\n\n       // Our custom method is mapped as well (since it uses POST)\n       card.$charge({amount: 9.99});\n           // POST: /users/123/cards/456?amount=9.99&charge=true {id: 456, number: '1234', name: 'J. Smith'}\n     });\n\n     // We can create an instance as well\n     var newCard = new CreditCard({number: '0123'});\n     newCard.name = 'Mike Smith';\n\n     var savePromise = newCard.$save();\n         // POST: /users/123/cards {number: '0123', name: 'Mike Smith'}\n         // server returns: {id: 789, number: '0123', name: 'Mike Smith'}\n\n     savePromise.then(function() {\n       // Once the promise is resolved, the created instance\n       // is populated with the data returned by the server\n       expect(newCard.id).toEqual(789);\n     });\n   ```\n *\n * The object returned from a call to `$resource` is a resource \"class\" which has one \"static\"\n * method for each action in the definition.\n *\n * Calling these methods invokes `$http` on the `url` template with the given HTTP `method`,\n * `params` and `headers`.\n *\n * @example\n *\n * ### Accessing the response\n *\n * When the data is returned from the server then the object is an instance of the resource type and\n * all of the non-GET methods are available with `$` prefix. This allows you to easily support CRUD\n * operations (create, read, update, delete) on server-side data.\n *\n   ```js\n     var User = $resource('/users/:userId', {userId: '@id'});\n     User.get({userId: 123}).$promise.then(function(user) {\n       user.abc = true;\n       user.$save();\n     });\n   ```\n *\n * It's worth noting that the success callback for `get`, `query` and other methods gets called with\n * the resource instance (populated with the data that came from the server) as well as an `$http`\n * header getter function, the HTTP status code and the response status text. So one could rewrite\n * the above example and get access to HTTP headers as follows:\n *\n   ```js\n     var User = $resource('/users/:userId', {userId: '@id'});\n     User.get({userId: 123}, function(user, getResponseHeaders) {\n       user.abc = true;\n       user.$save(function(user, putResponseHeaders) {\n         // `user` => saved `User` object\n         // `putResponseHeaders` => `$http` header getter\n       });\n     });\n   ```\n *\n * @example\n *\n * ### Creating custom actions\n *\n * In this example we create a custom method on our resource to make a PUT request:\n *\n   ```js\n      var app = angular.module('app', ['ngResource']);\n\n      // Some APIs expect a PUT request in the format URL/object/ID\n      // Here we are creating an 'update' method\n      app.factory('Notes', ['$resource', function($resource) {\n        return $resource('/notes/:id', {id: '@id'}, {\n          update: {method: 'PUT'}\n        });\n      }]);\n\n      // In our controller we get the ID from the URL using `$location`\n      app.controller('NotesCtrl', ['$location', 'Notes', function($location, Notes) {\n        // First, retrieve the corresponding `Note` object from the server\n        // (Assuming a URL of the form `.../notes?id=XYZ`)\n        var noteId = $location.search().id;\n        var note = Notes.get({id: noteId});\n\n        note.$promise.then(function() {\n          note.content = 'Hello, world!';\n\n          // Now call `update` to save the changes on the server\n          Notes.update(note);\n              // This will PUT /notes/ID with the note object as the request payload\n\n          // Since `update` is a non-GET method, it will also be available on the instance\n          // (prefixed with `$`), so we could replace the `Note.update()` call with:\n          //note.$update();\n        });\n      }]);\n   ```\n *\n * @example\n *\n * ### Cancelling requests\n *\n * If an action's configuration specifies that it is cancellable, you can cancel the request related\n * to an instance or collection (as long as it is a result of a \"non-instance\" call):\n *\n   ```js\n     // ...defining the `Hotel` resource...\n     var Hotel = $resource('/api/hotels/:id', {id: '@id'}, {\n       // Let's make the `query()` method cancellable\n       query: {method: 'get', isArray: true, cancellable: true}\n     });\n\n     // ...somewhere in the PlanVacationController...\n     ...\n     this.onDestinationChanged = function onDestinationChanged(destination) {\n       // We don't care about any pending request for hotels\n       // in a different destination any more\n       if (this.availableHotels) {\n         this.availableHotels.$cancelRequest();\n       }\n\n       // Let's query for hotels in `destination`\n       // (calls: /api/hotels?location=<destination>)\n       this.availableHotels = Hotel.query({location: destination});\n     };\n   ```\n *\n * @example\n *\n * ### Using interceptors\n *\n * You can use interceptors to transform the request or response, perform additional operations, and\n * modify the returned instance/collection. The following example, uses `request` and `response`\n * interceptors to augment the returned instance with additional info:\n *\n   ```js\n     var Thing = $resource('/api/things/:id', {id: '@id'}, {\n       save: {\n         method: 'POST',\n         interceptor: {\n           request: function(config) {\n             // Before the request is sent out, store a timestamp on the request config\n             config.requestTimestamp = Date.now();\n             return config;\n           },\n           response: function(response) {\n             // Get the instance from the response object\n             var instance = response.resource;\n\n             // Augment the instance with a custom `saveLatency` property, computed as the time\n             // between sending the request and receiving the response.\n             instance.saveLatency = Date.now() - response.config.requestTimestamp;\n\n             // Return the instance\n             return instance;\n           }\n         }\n       }\n     });\n\n     Thing.save({foo: 'bar'}).$promise.then(function(thing) {\n       console.log('That thing was saved in ' + thing.saveLatency + 'ms.');\n     });\n   ```\n *\n */\nangular.module('ngResource', ['ng']).\n  info({ angularVersion: '1.8.2' }).\n  provider('$resource', function ResourceProvider() {\n    var PROTOCOL_AND_IPV6_REGEX = /^https?:\\/\\/\\[[^\\]]*][^/]*/;\n\n    var provider = this;\n\n    /**\n     * @ngdoc property\n     * @name $resourceProvider#defaults\n     * @description\n     * Object containing default options used when creating `$resource` instances.\n     *\n     * The default values satisfy a wide range of usecases, but you may choose to overwrite any of\n     * them to further customize your instances.

The actions can also be enhanced or overwritten per resource\n     *   class.<br />\n     *   The default actions are:\n     *   ```js\n     *   {\n     *     get: {method: 'GET'},\n     *     save: {method: 'POST'},\n     *     query: {method: 'GET', isArray: true},\n     *     remove: {method: 'DELETE'},\n     *     delete: {method: 'DELETE'}\n     *   }\n     *   ```\n     *\n     * #### Example\n     *\n     * For example, you can specify a new `update` action that uses the `PUT` HTTP verb:\n     *\n     * ```js\n     *   angular.\n     *     module('myApp').\n     *     config(['$resourceProvider', function ($resourceProvider) {\n     *       $resourceProvider.defaults.actions.update = {\n     *         method: 'PUT'\n     *       };\n     *     }]);\n     * ```\n     *\n     * Or you can even overwrite the whole `actions` list and specify your own:\n     *\n     * ```js\n     *   angular.\n     *     module('myApp').\n     *     config(['$resourceProvider', function ($resourceProvider) {\n     *       $resourceProvider.defaults.actions = {\n     *         create: {method: 'POST'},\n     *         get:    {method: 'GET'},\n     *         getAll: {method: 'GET', isArray:true},\n     *         update: {method: 'PUT'},\n     *         delete: {method: 'DELETE'}\n     *       };\n     *     });\n     * ```\n     *\n     */\n    this.defaults = {\n      // Strip slashes by default\n      stripTrailingSlashes: true,\n\n      // Make non-instance requests cancellable (via `$cancelRequest()`)\n      cancellable: false,\n\n      // Default actions configuration\n      actions: {\n        'get': {method: 'GET'},\n        'save': {method: 'POST'},\n        'query': {method: 'GET', isArray: true},\n        'remove': {method: 'DELETE'},\n        'delete': {method: 'DELETE'}\n      }\n    };\n\n    this.$get = ['$http', '$log', '$q', '$timeout', function($http, $log, $q, $timeout) {\n\n      var noop = angular.noop,\n          forEach = angular.forEach,\n          extend = angular.extend,\n          copy = angular.copy,\n          isArray = angular.isArray,\n          isDefined = angular.isDefined,\n          isFunction = angular.isFunction,\n          isNumber = angular.isNumber,\n          encodeUriQuery = angular.$$encodeUriQuery,\n          encodeUriSegment = angular.$$encodeUriSegment;\n\n      function Route(template, defaults) {\n        this.template = template;\n        this.defaults = extend({}, provider.defaults, defaults);\n        this.urlParams = {};\n      }\n\n      Route.prototype = {\n        setUrlParams: function(config, params, actionUrl) {\n          var self = this,\n            url = actionUrl || self.template,\n            val,\n            encodedVal,\n            protocolAndIpv6 = '';\n\n          var urlParams = self.urlParams = Object.create(null);\n          forEach(url.split(/\\W/), function(param) {\n            if (param === 'hasOwnProperty') {\n              throw $resourceMinErr('badname', 'hasOwnProperty is not a valid parameter name.');\n            }\n            if (!(new RegExp('^\\\\d+$').test(param)) && param &&\n              (new RegExp('(^|[^\\\\\\\\]):' + param + '(\\\\W|$)').test(url))) {\n              urlParams[param] = {\n                isQueryParamValue: (new RegExp('\\\\?.*=:' + param + '(?:\\\\W|$)')).test(url)\n              };\n            }\n          });\n          url = url.replace(/\\\\:/g, ':');\n          url = url.replace(PROTOCOL_AND_IPV6_REGEX, function(match) {\n            protocolAndIpv6 = match;\n            return '';\n          });\n\n          params = params || {};\n          forEach(self.urlParams, function(paramInfo, urlParam) {\n            val = params.hasOwnProperty(urlParam) ?

The `ngApp` directive\n * designates the **root element** of the application and is typically placed near the root element\n * of the page - e.g. on the `` or `` tags.\n *\n * There are a few things to keep in mind when using `ngApp`:\n * - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`\n * found in the document will be used to define the root element to auto-bootstrap as an\n * application. To run multiple applications in an HTML document you must manually bootstrap them using\n * {@link angular.bootstrap} instead.\n * - AngularJS applications cannot be nested within each other.\n * - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.\n * This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and\n * {@link ngRoute.ngView `ngView`}.\n * Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},\n * causing animations to stop working and making the injector inaccessible from outside the app.\n *\n * You can specify an **AngularJS module** to be used as the root module for the application. This\n * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It\n * should contain the application code needed or have dependencies on other modules that will\n * contain the code. See {@link angular.module} for more information.\n *\n * In the example below if the `ngApp` directive were not placed on the `html` element then the\n * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`\n * would not be resolved to `3`.\n *\n * @example\n *\n * ### Simple Usage\n *\n * `ngApp` is the easiest, and most common way to bootstrap an application.\n *\n \n \n

@description\n * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.\n *\n * If jQuery is available, `angular.element` is an alias for the\n * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`\n * delegates to AngularJS's built-in subset of jQuery, called \"jQuery lite\" or **jqLite**.\n *\n * jqLite is a tiny, API-compatible subset of jQuery that allows\n * AngularJS to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most\n * commonly needed functionality with the goal of having a very small footprint.\n *\n * To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the\n * {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a\n * specific version of jQuery if multiple versions exist on the page.\n *\n *

**Note:** All element references in AngularJS are always wrapped with jQuery or\n * jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.

\n *\n *

**Note:** Keep in mind that this function will not find elements\n * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`\n * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.

\n *\n * ## AngularJS's jqLite\n * jqLite provides only the following jQuery methods:\n *\n * - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument\n * - [`after()`](http://api.jquery.com/after/)\n * - [`append()`](http://api.jquery.com/append/) - Contrary to jQuery, this doesn't clone elements\n * so will not work correctly when invoked on a jqLite object containing more than one DOM node\n * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters\n * - [`bind()`](http://api.jquery.com/bind/) (_deprecated_, use [`on()`](http://api.jquery.com/on/)) - Does not support namespaces, selectors or eventData\n * - [`children()`](http://api.jquery.com/children/) - Does not support selectors\n * - [`clone()`](http://api.jquery.com/clone/)\n * - [`contents()`](http://api.jquery.com/contents/)\n * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.\n * As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.\n * - [`data()`](http://api.jquery.com/data/)\n * - [`detach()`](http://api.jquery.com/detach/)\n * - [`empty()`](http://api.jquery.com/empty/)\n * - [`eq()`](http://api.jquery.com/eq/)\n * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name\n * - [`hasClass()`](http://api.jquery.com/hasClass/)\n * - [`html()`](http://api.jquery.com/html/)\n * - [`next()`](http://api.jquery.com/next/) - Does not support selectors\n * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData\n * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter\n * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors\n * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors\n * - [`prepend()`](http://api.jquery.com/prepend/)\n * - [`prop()`](http://api.jquery.com/prop/)\n * - [`ready()`](http://api.jquery.com/ready/) (_deprecated_, use `angular.element(callback)` instead of `angular.element(document).ready(callback)`)\n * - [`remove()`](http://api.jquery.com/remove/)\n * - [`removeAttr()`](http://api.jquery.com/removeAttr/) - Does not support multiple attributes\n * - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument\n * - [`removeData()`](http://api.jquery.com/removeData/)\n * - [`replaceWith()`](http://api.jquery.com/replaceWith/)\n * - [`text()`](http://api.jquery.com/text/)\n * - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument\n * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers\n * - [`unbind()`](http://api.jquery.com/unbind/) (_deprecated_, use [`off()`](http://api.jquery.com/off/)) - Does not support namespaces or event object as parameter\n * - [`val()`](http://api.jquery.com/val/)\n * - [`wrap()`](http://api.jquery.com/wrap/)\n *\n * jqLite also provides a method restoring pre-1.8 insecure treatment of XHTML-like tags.\n * This legacy behavior turns input like `

` to `

`\n * instead of `

` like version 1.8 & newer do. To restore it, invoke:\n * ```js\n * angular.UNSAFE_restoreLegacyJqLiteXHTMLReplacement();\n * ```\n * Note that this only patches jqLite. If you use jQuery 3.5.0 or newer, please read the\n * [jQuery 3.5 upgrade guide](https://jquery.com/upgrade-guide/3.5/) for more details\n * about the workarounds.\n *\n * ## jQuery/jqLite Extras\n * AngularJS also provides the following additional methods and events to both jQuery and jqLite:\n *\n * ### Events\n * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event\n * on all DOM nodes being removed. This can be used to clean up any 3rd party bindings to the DOM\n * element before it is removed.\n *\n * ### Methods\n * - `controller(name)` - retrieves the controller of the current element or its parent. By default\n * retrieves controller associated with the `ngController` directive. If `name` is provided as\n * camelCase directive name, then the controller for this directive will be retrieved (e.g.\n * `'ngModel'`).\n * - `injector()` - retrieves the injector of the current element or its parent.\n * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current\n * element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to\n * be enabled.\n * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the\n * current element. This getter should be used only on elements that contain a directive which starts a new isolate\n * scope. Calling `scope()` on this element always returns the original non-isolate scope.\n * Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.\n * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top\n * parent element is reached.\n *\n * @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See\n * https://github.com/angular/angular.js/issues/14251 for more information.\n *\n * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.\n * @returns {Object} jQuery object.\n */\n\nJQLite.expando = 'ng339';\n\nvar jqCache = JQLite.cache = {},\n jqId = 1;\n\n/*\n * !!!

There are three ways in which the function can be annotated with the needed\n * dependencies.\n *\n * #### Argument names\n *\n * The simplest form is to extract the dependencies from the arguments of the function.

In these situations using the array notation to specify the dependencies in\n * a way that survives minification is a better choice:\n *\n * ```js\n * // We wish to write this (not minification / obfuscation safe)\n * injector.invoke(function($compile, $rootScope) {\n * // ...\n * });\n *\n * // We are forced to write break inlining\n * var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {\n * // ...\n * };\n * tmpFn.$inject = ['$compile', '$rootScope'];\n * injector.invoke(tmpFn);\n *\n * // To better support inline function the inline annotation is supported\n * injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {\n * // ...\n * }]);\n *\n * // Therefore\n * expect(injector.annotate(\n * ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])\n * ).toEqual(['$compile', '$rootScope']);\n * ```\n *\n * @param {Function|Array.} fn Function for which dependent service names need to\n * be retrieved as described above.\n *\n * @param {boolean=} [strictDi=false] Disallow argument name annotation inference.\n *\n * @returns {Array.} The names of the services which the function requires.\n */\n/**\n * @ngdoc method\n * @name $injector#loadNewModules\n *\n * @description\n *\n * **This is a dangerous API, which you use at your own risk!**\n *\n * Add the specified modules to the current injector.\n *\n * This method will add each of the injectables to the injector and execute all of the config and run\n * blocks for each module passed to the method.\n *\n * If a module has already been loaded into the injector then it will not be loaded again.\n *\n * * The application developer is responsible for loading the code containing the modules; and for\n * ensuring that lazy scripts are not downloaded and executed more often that desired.\n * * Previously compiled HTML will not be affected by newly loaded directives, filters and components.\n * * Modules cannot be unloaded.\n *\n * You can use {@link $injector#modules `$injector.modules`} to check whether a module has been loaded\n * into the injector, which may indicate whether the script has been executed already.\n *\n * @example\n * Here is an example of loading a bundle of modules, with a utility method called `getScript`:\n *\n * ```javascript\n * app.factory('loadModule', function($injector) {\n * return function loadModule(moduleName, bundleUrl) {\n * return getScript(bundleUrl).then(function() { $injector.loadNewModules([moduleName]); });\n * };\n * })\n * ```\n *\n * @param {Array=} mods an array of modules to load into the application.\n * Each item in the array should be the name of a predefined module or a (DI annotated)\n * function that will be invoked by the injector as a `config` block.\n * See: {@link angular.module modules}\n */\n\n\n/**\n * @ngdoc service\n * @name $provide\n *\n * @description\n *\n * The {@link auto.$provide $provide} service has a number of methods for registering components\n * with the {@link auto.$injector $injector}.

These **service\n * factories** are functions which, in turn, are created by a **service provider**.\n * The **service providers** are constructor functions. When instantiated they must contain a\n * property called `$get`, which holds the **service factory** function.\n *\n * When you request a service, the {@link auto.$injector $injector} is responsible for finding the\n * correct **service provider**, instantiating it and then calling its `$get` **service factory**\n * function to get the instance of the **service**.\n *\n * Often services have no configuration options and there is no need to add methods to the service\n * provider. The provider will be no more than a constructor function with a `$get` property. For\n * these cases the {@link auto.$provide $provide} service has additional helper methods to register\n * services without specifying a provider.\n *\n * * {@link auto.$provide#provider provider(name, provider)} - registers a **service provider** with the\n * {@link auto.$injector $injector}\n * * {@link auto.$provide#constant constant(name, obj)} - registers a value/object that can be accessed by\n * providers and services.\n * * {@link auto.$provide#value value(name, obj)} - registers a value/object that can only be accessed by\n * services, not providers.\n * * {@link auto.$provide#factory factory(name, fn)} - registers a service **factory function**\n * that will be wrapped in a **service provider** object, whose `$get` property will contain the\n * given factory function.\n * * {@link auto.$provide#service service(name, Fn)} - registers a **constructor function**\n * that will be wrapped in a **service provider** object, whose `$get` property will instantiate\n * a new object using the given constructor function.\n * * {@link auto.$provide#decorator decorator(name, decorFn)} - registers a **decorator function** that\n * will be able to modify or replace the implementation of another service.\n *\n * See the individual methods for more information and examples.\n */\n\n/**\n * @ngdoc method\n * @name $provide#provider\n * @description\n *\n * Register a **provider function** with the {@link auto.$injector $injector}.

Importantly, you can configure what kind of service is created by the `$get`\n * method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a\n * method {@link ng.$logProvider#debugEnabled debugEnabled}\n * which lets you specify whether the {@link ng.$log $log} service will log debug messages to the\n * console or not.\n *\n * It is possible to inject other providers into the provider function,\n * but the injected provider must have been defined before the one that requires it.\n *\n * @param {string} name The name of the instance. NOTE: the provider will be available under `name +\n 'Provider'` key.\n * @param {(Object|function())} provider If the provider is:\n *\n * - `Object`: then it should have a `$get` method.

\n * **Note:** This document is an in-depth reference of all directive options.\n * For a gentle introduction to directives with examples of common use cases,\n * see the {@link guide/directive directive guide}.\n *

\n *\n * ## Comprehensive Directive API\n *\n * There are many different options for a directive.\n *\n * The difference resides in the return value of the factory function.\n * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)}\n * that defines the directive properties, or just the `postLink` function (all other properties will have\n * the default values).\n *\n *

\n * **Best Practice:** It's recommended to use the \"directive definition object\" form.\n *

\n *\n * Here's an example directive declared with a Directive Definition Object:\n *\n * ```js\n * var myModule = angular.module(...);\n *\n * myModule.directive('directiveName', function factory(injectables) {\n * var directiveDefinitionObject = {\n * {@link $compile#-priority- priority}: 0,\n * {@link $compile#-template- template}: '

', // or // function(tElement, tAttrs) { ... },\n * // or\n * // {@link $compile#-templateurl- templateUrl}: 'directive.html', // or // function(tElement, tAttrs) { ... },\n * {@link $compile#-transclude- transclude}: false,\n * {@link $compile#-restrict- restrict}: 'A',\n * {@link $compile#-templatenamespace- templateNamespace}: 'html',\n * {@link $compile#-scope- scope}: false,\n * {@link $compile#-controller- controller}: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },\n * {@link $compile#-controlleras- controllerAs}: 'stringIdentifier',\n * {@link $compile#-bindtocontroller- bindToController}: false,\n * {@link $compile#-require- require}: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],\n * {@link $compile#-multielement- multiElement}: false,\n * {@link $compile#-compile- compile}: function compile(tElement, tAttrs, transclude) {\n * return {\n * {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },\n * {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }\n * }\n * // or\n * // return function postLink( ... ) { ... }\n * },\n * // or\n * // {@link $compile#-link- link}: {\n * // {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },\n * // {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }\n * // }\n * // or\n * // {@link $compile#-link- link}: function postLink( ... ) { ... }\n * };\n * return directiveDefinitionObject;\n * });\n * ```\n *\n *

\n * **Note:** Any unspecified options will use the default value. You can see the default values below.\n *

\n *\n * Therefore the above can be simplified as:\n *\n * ```js\n * var myModule = angular.module(...);\n *\n * myModule.directive('directiveName', function factory(injectables) {\n * var directiveDefinitionObject = {\n * link: function postLink(scope, iElement, iAttrs) { ... }\n * };\n * return directiveDefinitionObject;\n * // or\n * // return function postLink(scope, iElement, iAttrs) { ... }\n * });\n * ```\n *\n * ### Life-cycle hooks\n * Directive controllers can provide the following methods that are called by AngularJS at points in the life-cycle of the\n * directive:\n * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and\n * had their bindings initialized (and before the pre & post linking functions for the directives on\n * this element). This is a good place to put initialization code for your controller.\n * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The\n * `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an\n * object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a\n * component such as cloning the bound value to prevent accidental mutation of the outer value. Note that this will\n * also be called when your bindings are initialized.\n * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on\n * changes. Any actions that you wish to take in response to the changes that you detect must be\n * invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook\n * could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not\n * be detected by AngularJS's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;\n * if detecting changes, you must store the previous value(s) for comparison to the current values.\n * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing\n * external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in\n * the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent\n * components will have their `$onDestroy()` hook called before child components.\n * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link\n * function this hook can be used to set up DOM event handlers and do direct DOM manipulation.\n * Note that child elements that contain `templateUrl` directives will not have been compiled and linked since\n * they are waiting for their template to load asynchronously and their own compilation and linking has been\n * suspended until that occurs.\n *\n * #### Comparison with life-cycle hooks in the new Angular\n * The new Angular also uses life-cycle hooks for its components. While the AngularJS life-cycle hooks are similar there are\n * some differences that you should be aware of, especially when it comes to moving your code from AngularJS to Angular:\n *\n * * AngularJS hooks are prefixed with `$`, such as `$onInit`. Angular hooks are prefixed with `ng`, such as `ngOnInit`.\n * * AngularJS hooks can be defined on the controller prototype or added to the controller inside its constructor.\n * In Angular you can only define hooks on the prototype of the Component class.\n * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in AngularJS than you would to\n * `ngDoCheck` in Angular.\n * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be\n * propagated throughout the application.\n * Angular does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an\n * error or do nothing depending upon the state of `enableProdMode()`.\n *\n * #### Life-cycle hook examples\n *\n * This example shows how you can check for mutations to a Date object even though the identity of the object\n * has not changed.\n *\n * \n * \n * angular.module('do-check-module', [])\n * .component('app', {\n * template:\n * 'Month: ' +\n * 'Date: {{ $ctrl.date }}' +\n * '',\n * controller: function() {\n * this.date = new Date();\n * this.month = this.date.getMonth();\n * this.updateDate = function() {\n * this.date.setMonth(this.month);\n * };\n * }\n * })\n * .component('test', {\n * bindings: { date: '<' },\n * template:\n * '

{{ $ctrl.log | json }}

',\n * controller: function() {\n * var previousValue;\n * this.log = [];\n * this.$doCheck = function() {\n * var currentValue = this.date && this.date.valueOf();\n * if (previousValue !== currentValue) {\n * this.log.push('doCheck: date mutated: ' + this.date);\n * previousValue = currentValue;\n * }\n * };\n * }\n * });\n * \n * \n * \n * \n * \n *\n * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the\n * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large\n * arrays or objects can have a negative impact on your application performance.)\n *\n * \n * \n *

\n * \n * \n * angular.module('do-check-module', [])\n * .component('test', {\n * bindings: { items: '<' },\n * template:\n * '

',\n * controller: function() {\n * this.log = [];\n *\n * this.$doCheck = function() {\n * if (this.items_ref !== this.items) {\n * this.log.push('doCheck: items changed');\n * this.items_ref = this.items;\n * }\n * if (!angular.equals(this.items_clone, this.items)) {\n * this.log.push('doCheck: items mutated');\n * this.items_clone = angular.copy(this.items);\n * }\n * };\n * }\n * });\n * \n * \n *\n *\n * ### Directive Definition Object\n *\n * The directive definition object provides instructions to the {@link ng.$compile\n * compiler}. The attributes are:\n *\n * #### `multiElement`\n * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between\n * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them\n * together as the directive elements. It is recommended that this feature be used on directives\n * which are not strictly behavioral (such as {@link ngClick}), and which\n * do not manipulate or replace child nodes (such as {@link ngInclude}).\n *\n * #### `priority`\n * When there are multiple directives defined on a single DOM element, sometimes it\n * is necessary to specify the order in which the directives are applied. The `priority` is used\n * to sort the directives before their `compile` functions get called. Priority is defined as a\n * number. Directives with greater numerical `priority` are compiled first. Pre-link functions\n * are also run in priority order, but post-link functions are run in reverse order. The order\n * of directives with the same priority is undefined. The default priority is `0`.\n *\n * #### `terminal`\n * If set to true then the current `priority` will be the last set of directives\n * which will execute (any directives at the current priority will still execute\n * as the order of execution on same `priority` is undefined). Note that expressions\n * and other directives used in the directive's template will also be excluded from execution.\n *\n * #### `scope`\n * The scope property can be `false`, `true`, or an object:\n *\n * * **`false` (default):** No scope will be created for the directive. The directive will use its\n * parent's scope.\n *\n * * **`true`:** A new child scope that prototypically inherits from its parent will be created for\n * the directive's element. If multiple directives on the same element request a new scope,\n * only one new scope is created.\n *\n * * **`{...}` (an object hash):** A new \"isolate\" scope is created for the directive's template.\n * The 'isolate' scope differs from normal scope in that it does not prototypically\n * inherit from its parent scope. This is useful when creating reusable components, which should not\n * accidentally read or modify data in the parent scope. Note that an isolate scope\n * directive without a `template` or `templateUrl` will not apply the isolate scope\n * to its children elements.\n *\n * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the\n * directive's element. These local properties are useful for aliasing values for templates. The keys in\n * the object hash map to the name of the property on the isolate scope; the values define how the property\n * is bound to the parent scope, via matching attributes on the directive's element:\n *\n * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is\n * always a string since DOM attributes are strings. If no `attr` name is specified then the\n * attribute name is assumed to be the same as the local name. Given `` and the isolate scope definition `scope: { localName:'@myAttr' }`,\n * the directive's scope property `localName` will reflect the interpolated value of `hello\n * {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's\n * scope. The `name` is read from the parent scope (not the directive's scope).\n *\n * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression\n * passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.\n * If no `attr` name is specified then the attribute name is assumed to be the same as the local\n * name. Given `` and the isolate scope definition `scope: {\n * localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the\n * value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in\n * `localModel` and vice versa. If the binding expression is non-assignable, or if the attribute\n * isn't optional and doesn't exist, an exception\n * ({@link error/$compile/nonassign `$compile:nonassign`}) will be thrown upon discovering changes\n * to the local value, since it will be impossible to sync them back to the parent scope.\n *\n * By default, the {@link ng.$rootScope.Scope#$watch `$watch`}\n * method is used for tracking changes, and the equality check is based on object identity.\n * However, if an object literal or an array literal is passed as the binding expression, the\n * equality check is done by value (using the {@link angular.equals} function). It's also possible\n * to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection\n * `$watchCollection`}: use `=*` or `=*attr`\n *\n * * `<` or `` and directive definition of\n * `scope: { localModel:'` and the isolate scope definition `scope: {\n * localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for\n * the `count = count + value` expression. Often it's desirable to pass data from the isolated scope\n * via an expression to the parent scope. This can be done by passing a map of local variable names\n * and values into the expression wrapper fn. For example, if the expression is `increment(amount)`\n * then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.\n *\n * All 4 kinds of bindings (`@`, `=`, `<`, and `&`) can be made optional by adding `?` to the expression.\n * The marker must come after the mode and before the attribute name.\n * See the {@link error/$compile/iscp Invalid Isolate Scope Definition error} for definition examples.\n * This is useful to refine the interface directives provide.\n * One subtle difference between optional and non-optional happens **when the binding attribute is not\n * set**:\n * - the binding is optional: the property will not be defined\n * - the binding is not optional: the property is defined\n *\n * ```js\n *app.directive('testDir', function() {\n return {\n scope: {\n notoptional: '=',\n optional: '=?',\n },\n bindToController: true,\n controller: function() {\n this.$onInit = function() {\n console.log(this.hasOwnProperty('notoptional')) // true\n console.log(this.hasOwnProperty('optional')) // false\n }\n }\n }\n })\n *```\n *\n *\n * ##### Combining directives with different scope defintions\n *\n * In general it's possible to apply more than one directive to one element, but there might be limitations\n * depending on the type of scope required by the directives. The following points will help explain these limitations.\n * For simplicity only two directives are taken into account, but it is also applicable for several directives:\n *\n * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope\n * * **child scope** + **no scope** => Both directives will share one single child scope\n * * **child scope** + **child scope** => Both directives will share one single child scope\n * * **isolated scope** + **no scope** => The isolated directive will use it's own created isolated scope. The other directive will use\n * its parent's scope\n * * **isolated scope** + **child scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives cannot\n * be applied to the same element.\n * * **isolated scope** + **isolated scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives\n * cannot be applied to the same element.\n *\n *\n * #### `bindToController`\n * This property is used to bind scope properties directly to the controller. It can be either\n * `true` or an object hash with the same format as the `scope` property.\n *\n * When an isolate scope is used for a directive (see above), `bindToController: true` will\n * allow a component to have its properties bound to the controller, rather than to scope.\n *\n * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller\n * properties. You can access these bindings once they have been initialized by providing a controller method called\n * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings\n * initialized.\n *\n * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.\n * This will set up the scope bindings to the controller directly. Note that `scope` can still be used\n * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate\n * scope (useful for component directives).\n *\n * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.\n *\n *\n * #### `controller`\n * Controller constructor function. The controller is instantiated before the\n * pre-linking phase and can be accessed by other directives (see\n * `require` attribute). This allows the directives to communicate with each other and augment\n * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:\n *\n * * `$scope` - Current scope associated with the element\n * * `$element` - Current element\n * * `$attrs` - Current attributes object for the element\n * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:\n * `function([scope], cloneLinkingFn, futureParentElement, slotName)`:\n * * `scope`: (optional) override the scope.\n * * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.\n * * `futureParentElement` (optional):\n * * defines the parent to which the `cloneLinkingFn` will add the cloned elements.\n * * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.\n * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)\n * and when the `cloneLinkingFn` is passed,\n * as those elements need to created and cloned in a special way when they are defined outside their\n * usual containers (e.g. like `

`\n * * `C` - Class: `

`\n * * `M` - Comment: ``\n *\n *\n * #### `templateNamespace`\n * String representing the document type used by the markup in the template.\n * AngularJS needs this information as those elements need to be created and cloned\n * in a special way when they are defined outside their usual containers like `

`.\n * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`\n * function api below) and returns a string value.\n *\n *\n * #### `templateUrl`\n * This is similar to `template` but the template is loaded from the specified URL, asynchronously.\n *\n * Because template loading is asynchronous the compiler will suspend compilation of directives on that element\n * for later when the template has been resolved. In the meantime it will continue to compile and link\n * sibling and parent elements as though this element had not contained any directives.\n *\n * The compiler does not suspend the entire compilation to wait for templates to be loaded because this\n * would result in the whole app \"stalling\" until all templates are loaded asynchronously - even in the\n * case when only one deeply nested directive has `templateUrl`.\n *\n * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}.\n *\n * You can specify `templateUrl` as a string representing the URL or as a function which takes two\n * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns\n * a string value representing the url. In either case, the template URL is passed through {@link\n * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.\n *\n *\n * #### `replace`\n *

\n * **Note:** `replace` is deprecated in AngularJS and has been removed in the new Angular (v2+).\n *

\n *\n * Specifies what the template should replace. Defaults to `false`.\n *\n * * `true` - the template will replace the directive's element.\n * * `false` - the template will replace the contents of the directive's element.\n *\n * The replacement process migrates all of the attributes / classes from the old element to the new\n * one. See the {@link guide/directive#template-expanding-directive\n * Directives Guide} for an example.\n *\n * There are very few scenarios where element replacement is required for the application function,\n * the main one being reusable custom components that are used within SVG contexts\n * (because SVG doesn't work with custom elements in the DOM tree).\n *\n * #### `transclude`\n * Extract the contents of the element where the directive appears and make it available to the directive.\n * The contents are compiled and provided to the directive as a **transclusion function**. See the\n * {@link $compile#transclusion Transclusion} section below.\n *\n *\n * #### `compile`\n *\n * ```js\n * function compile(tElement, tAttrs, transclude) { ... }\n * ```\n *\n * The compile function deals with transforming the template DOM. Since most directives do not do\n * template transformation, it is not used often. The compile function takes the following arguments:\n *\n * * `tElement` - template element - The element where the directive has been declared. It is\n * safe to do template transformation on the element and child elements only.\n *\n * * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared\n * between all directive compile functions.\n *\n * * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`\n *\n *

\n * **Note:** The template instance and the link instance may be different objects if the template has\n * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that\n * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration\n * should be done in a linking function rather than in a compile function.\n *

\n\n *

\n * **Note:** The compile function cannot handle directives that recursively use themselves in their\n * own templates or compile functions. Compiling these directives results in an infinite loop and\n * stack overflow errors.\n *\n * This can be avoided by manually using `$compile` in the postLink function to imperatively compile\n * a directive's template instead of relying on automatic template compilation via `template` or\n * `templateUrl` declaration or manual compilation inside the compile function.\n *

\n *\n *

\n * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it\n * e.g. does not know about the right outer scope. Please use the transclude function that is passed\n * to the link function instead.\n *

\n\n * A compile function can have a return value which can be either a function or an object.\n *\n * * returning a (post-link) function - is equivalent to registering the linking function via the\n * `link` property of the config object when the compile function is empty.\n *\n * * returning an object with function(s) registered via `pre` and `post` properties - allows you to\n * control when a linking function should be called during the linking phase. See info about\n * pre-linking and post-linking functions below.\n *\n *\n * #### `link`\n * This property is used only if the `compile` property is not defined.\n *\n * ```js\n * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }\n * ```\n *\n * The link function is responsible for registering DOM listeners as well as updating the DOM. It is\n * executed after the template has been cloned. This is where most of the directive logic will be\n * put.\n *\n * * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the\n * directive for registering {@link ng.$rootScope.Scope#$watch watches}.\n *\n * * `iElement` - instance element - The element where the directive is to be used. It is safe to\n * manipulate the children of the element only in `postLink` function since the children have\n * already been linked.\n *\n * * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared\n * between all directive linking functions.\n *\n * * `controller` - the directive's required controller instance(s) - Instances are shared\n * among all directives, which allows the directives to use the controllers as a communication\n * channel. The exact value depends on the directive's `require` property:\n * * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one\n * * `string`: the controller instance\n * * `array`: array of controller instances\n *\n * If a required controller cannot be found, and it is optional, the instance is `null`,\n * otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.\n *\n * Note that you can also require the directive's own controller - it will be made available like\n * any other controller.\n *\n * * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.\n * This is the same as the `$transclude` parameter of directive controllers,\n * see {@link ng.$compile#-controller- the controller section for details}.\n * `function([scope], cloneLinkingFn, futureParentElement)`.\n *\n * #### Pre-linking function\n *\n * Executed before the child elements are linked. Not safe to do DOM transformation since the\n * compiler linking function will fail to locate the correct elements for linking.\n *\n * #### Post-linking function\n *\n * Executed after the child elements are linked.\n *\n * Note that child elements that contain `templateUrl` directives will not have been compiled\n * and linked since they are waiting for their template to load asynchronously and their own\n * compilation and linking has been suspended until that occurs.\n *\n * It is safe to do DOM transformation in the post-linking function on elements that are not waiting\n * for their async templates to be resolved.\n *\n *\n * ### Transclusion\n *\n * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and\n * copying them to another part of the DOM, while maintaining their connection to the original AngularJS\n * scope from where they were taken.\n *\n * Transclusion is used (often with {@link ngTransclude}) to insert the\n * original contents of a directive's element into a specified place in the template of the directive.\n * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded\n * content has access to the properties on the scope from which it was taken, even if the directive\n * has isolated scope.\n * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.\n *\n * This makes it possible for the widget to have private state for its template, while the transcluded\n * content has access to its originating scope.\n *\n *

\n * **Note:** When testing an element transclude directive you must not place the directive at the root of the\n * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives\n * Testing Transclusion Directives}.\n *

\n *\n * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the\n * directive's element, the entire element or multiple parts of the element contents:\n *\n * * `true` - transclude the content (i.e. the child nodes) of the directive's element.\n * * `'element'` - transclude the whole of the directive's element including any directives on this\n * element that are defined at a lower priority than this directive. When used, the `template`\n * property is ignored.\n * * **`{...}` (an object hash):** - map elements of the content onto transclusion \"slots\" in the template.\n *\n * **Multi-slot transclusion** is declared by providing an object for the `transclude` property.\n *\n * This object is a map where the keys are the name of the slot to fill and the value is an element selector\n * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)\n * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).\n *\n * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}.\n *\n * If the element selector is prefixed with a `?` then that slot is optional.\n *\n * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `` elements to\n * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.\n *\n * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements\n * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call\n * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and\n * injectable into the directive's controller.\n *\n *\n * #### Transclusion Functions\n *\n * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion\n * function** to the directive's `link` function and `controller`. This transclusion function is a special\n * **linking function** that will return the compiled contents linked to a new transclusion scope.\n *\n *

\n * If you are just using {@link ngTransclude} then you don't need to worry about this function, since\n * ngTransclude will deal with it for us.\n *

\n *\n * If you want to manually control the insertion and removal of the transcluded content in your directive\n * then you must use this transclude function. When you call a transclude function it returns a jqLite/JQuery\n * object that contains the compiled DOM, which is linked to the correct transclusion scope.\n *\n * When you call a transclusion function you can pass in a **clone attach function**. This function accepts\n * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded\n * content and the `scope` is the newly created transclusion scope, which the clone will be linked to.\n *\n *

\n * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function\n * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.\n *

\n *\n * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone\n * attach function**:\n *\n * ```js\n * var transcludedContent, transclusionScope;\n *\n * $transclude(function(clone, scope) {\n * element.append(clone);\n * transcludedContent = clone;\n * transclusionScope = scope;\n * });\n * ```\n *\n * Later, if you want to remove the transcluded content from your DOM then you should also destroy the\n * associated transclusion scope:\n *\n * ```js\n * transcludedContent.remove();\n * transclusionScope.$destroy();\n * ```\n *\n *

\n * **Best Practice**: if you intend to add and remove transcluded content manually in your directive\n * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),\n * then you are also responsible for calling `$destroy` on the transclusion scope.\n *

\n *\n * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}\n * automatically destroy their transcluded clones as necessary so you do not need to worry about this if\n * you are simply using {@link ngTransclude} to inject the transclusion into your directive.\n *\n *\n * #### Transclusion Scopes\n *\n * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion\n * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed\n * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it\n * was taken.\n *\n * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look\n * like this:\n *\n * ```html\n *

\n *

\n * ```\n *\n * The `$parent` scope hierarchy will look like this:\n *\n ```\n - $rootScope\n - isolate\n - transclusion\n ```\n *\n * but the scopes will inherit prototypically from different scopes to their `$parent`.\n *\n ```\n - $rootScope\n - transclusion\n - isolate\n ```\n *\n *\n * ### Attributes\n *\n * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the\n * `link()` or `compile()` functions. It has a variety of uses.\n *\n * * *Accessing normalized attribute names:* Directives like `ngBind` can be expressed in many ways:\n * `ng:bind`, `data-ng-bind`, or `x-ng-bind`. The attributes object allows for normalized access\n * to the attributes.\n *\n * * *Directive inter-communication:* All directives share the same instance of the attributes\n * object which allows the directives to use the attributes object as inter directive\n * communication.\n *\n * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object\n * allowing other directives to read the interpolated value.\n *\n * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes\n * that contain interpolation (e.g. `src=\"{{bar}}\"`). Not only is this very efficient but it's also\n * the only way to easily get the actual value because during the linking phase the interpolation\n * hasn't been evaluated yet and so the value is at this time set to `undefined`.\n *\n * ```js\n * function linkingFn(scope, elm, attrs, ctrl) {\n * // get the attribute value\n * console.log(attrs.ngModel);\n *\n * // change the attribute\n * attrs.$set('ngModel', 'new value');\n *\n * // observe changes to interpolated attribute\n * attrs.$observe('ngModel', function(value) {\n * console.log('ngModel has changed value to ' + value);\n * });\n * }\n * ```\n *\n * ## Example\n *\n *

\n * **Note**: Typically directives are registered with `module.directive`. The example below is\n * to illustrate how `$compile` works.\n *

\n *\n \n \n \n

\n
\n
\n

\n \n \n it('should auto compile', function() {\n var textarea = $('textarea');\n var output = $('div[compile]');\n // The initial state reads 'Hello AngularJS'.\n expect(output.getText()).toBe('Hello AngularJS');\n textarea.clear();\n textarea.sendKeys('{{name}}!');\n expect(output.getText()).toBe('AngularJS!');\n });\n \n \n\n *\n *\n * @param {string|DOMElement} element Element or HTML string to compile into a template function.\n * @param {function(angular.Scope, cloneAttachFn=)} transclude function available to directives - DEPRECATED.\n *\n *

\n * **Note:** Passing a `transclude` function to the $compile function is deprecated, as it\n * e.g. will not use the right outer scope. Please pass the transclude function as a\n * `parentBoundTranscludeFn` to the link function instead.\n *

\n *\n * @param {number} maxPriority only apply directives lower than given priority (Only effects the\n * root element(s), not their children)\n * @returns {function(scope, cloneAttachFn=, options=)} a link function which is used to bind template\n * (a DOM element/tree) to a scope. Where:\n *\n * * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.\n * * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the\n * `template` and call the `cloneAttachFn` function allowing the caller to attach the\n * cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is\n * called as:
`cloneAttachFn(clonedElement, scope)` where:\n *\n * * `clonedElement` - is a clone of the original `element` passed into the compiler.\n * * `scope` - is the current scope with which the linking function is working with.\n *\n * * `options` - An optional object hash with linking options. If `options` is provided, then the following\n * keys may be used to control linking behavior:\n *\n * * `parentBoundTranscludeFn` - the transclude function made available to\n * directives; if given, it will be passed through to the link functions of\n * directives found in `element` during compilation.\n * * `transcludeControllers` - an object hash with keys that map controller names\n * to a hash with the key `instance`, which maps to the controller instance;\n * if given, it will make the controllers available to directives on the compileNode:\n * ```\n * {\n * parent: {\n * instance: parentControllerInstance\n * }\n * }\n * ```\n * * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add\n * the cloned elements; only needed for transcludes that are allowed to contain non HTML\n * elements (e.g. SVG elements). See also the `directive.controller` property.\n *\n * Calling the linking function returns the element of the template. It is either the original\n * element passed in, or the clone of the element if the `cloneAttachFn` is provided.\n *\n * After linking the view is not updated until after a call to `$digest`, which typically is done by\n * AngularJS automatically.\n *\n * If you need access to the bound view, there are two ways to do it:\n *\n * - If you are not asking the linking function to clone the template, create the DOM element(s)\n * before you send them to the compiler and keep this reference around.\n * ```js\n * var element = angular.element('

');\n * $compile(element)(scope);\n * ```\n *\n * - if on the other hand, you need the element to be cloned, the view reference from the original\n * example would not point to the clone, but rather to the original template that was cloned. In\n * this case, you can access the clone either via the `cloneAttachFn` or the value returned by the\n * linking function:\n * ```js\n * var templateElement = angular.element('

');\n * var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {\n * // Attach the clone to DOM document at the right place.\n * });\n *\n * // Now we have reference to the cloned DOM via `clonedElement`.\n * // NOTE: The `clonedElement` returned by the linking function is the same as the\n * // `clonedElement` passed to `cloneAttachFn`.\n * ```\n *\n *\n * For information on how the compiler works, see the\n * {@link guide/compiler AngularJS HTML Compiler} section of the Developer Guide.\n *\n * @knownIssue\n *\n * ### Double Compilation\n *\n Double compilation occurs when an already compiled part of the DOM gets\n compiled again. This is an undesired effect and can lead to misbehaving directives, performance issues,\n and memory leaks. Refer to the Compiler Guide {@link guide/compiler#double-compilation-and-how-to-avoid-it\n section on double compilation} for an in-depth explanation and ways to avoid it.\n\n * @knownIssue\n\n ### Issues with `replace: true`\n *\n *

\n * **Note**: {@link $compile#-replace- `replace: true`} is deprecated and not recommended to use,\n * mainly due to the issues listed here. It has been completely removed in the new Angular.\n *

\n *\n * #### Attribute values are not merged\n *\n * When a `replace` directive encounters the same attribute on the original and the replace node,\n * it will simply deduplicate the attribute and join the values with a space or with a `;` in case of\n * the `style` attribute.\n * ```html\n * Original Node: \n * Replace Template: \n * Result: \n * ```\n *\n * That means attributes that contain AngularJS expressions will not be merged correctly, e.g.\n * {@link ngShow} or {@link ngClass} will cause a {@link $parse} error:\n *\n * ```html\n * Original Node: \n * Replace Template: \n * Result: \n * ```\n *\n * See issue [#5695](https://github.com/angular/angular.js/issues/5695).\n *\n * #### Directives are not deduplicated before compilation\n *\n * When the original node and the replace template declare the same directive(s), they will be\n * {@link guide/compiler#double-compilation-and-how-to-avoid-it compiled twice} because the compiler\n * does not deduplicate them. In many cases, this is not noticeable, but e.g. {@link ngModel} will\n * attach `$formatters` and `$parsers` twice.\n *\n * See issue [#2573](https://github.com/angular/angular.js/issues/2573).\n *\n * #### `transclude: element` in the replace template root can have unexpected effects\n *\n * When the replace template has a directive at the root node that uses\n * {@link $compile#-transclude- `transclude: element`}, e.g.\n * {@link ngIf} or {@link ngRepeat}, the DOM structure or scope inheritance can be incorrect.\n * See the following issues:\n *\n * - Incorrect scope on replaced element:\n * [#9837](https://github.com/angular/angular.js/issues/9837)\n * - Different DOM between `template` and `templateUrl`:\n * [#10612](https://github.com/angular/angular.js/issues/14326)\n *\n */\n\n/**\n * @ngdoc directive\n * @name ngProp\n * @restrict A\n * @element ANY\n *\n * @usage\n *\n * ```html\n * \n * \n * ```\n *\n * or with uppercase letters in property (e.g. \"propName\"):\n *\n *\n * ```html\n * \n * \n * ```\n *\n *\n * @description\n * The `ngProp` directive binds an expression to a DOM element property.\n * `ngProp` allows writing to arbitrary properties by including\n * the property name in the attribute, e.g. `ng-prop-value=\"'my value'\"` binds 'my value' to\n * the `value` property.\n *\n * Usually, it's not necessary to write to properties in AngularJS, as the built-in directives\n * handle the most common use cases (instead of the above example, you would use {@link ngValue}).\n *\n * However, [custom elements](https://developer.mozilla.org/docs/Web/Web_Components/Using_custom_elements)\n * often use custom properties to hold data, and `ngProp` can be used to provide input to these\n * custom elements.\n *\n * ## Binding to camelCase properties\n *\n * Since HTML attributes are case-insensitive, camelCase properties like `innerHTML` must be escaped.\n * AngularJS uses the underscore (_) in front of a character to indicate that it is uppercase, so\n * `innerHTML` must be written as `ng-prop-inner_h_t_m_l=\"expression\"` (Note that this is just an\n * example, and for binding HTML {@link ngBindHtml} should be used.\n *\n * ## Security\n *\n * Binding expressions to arbitrary properties poses a security risk, as properties like `innerHTML`\n * can insert potentially dangerous HTML into the application, e.g. script tags that execute\n * malicious code.\n * For this reason, `ngProp` applies Strict Contextual Escaping with the {@link ng.$sce $sce service}.\n * This means vulnerable properties require their content to be \"trusted\", based on the\n * context of the property. For example, the `innerHTML` is in the `HTML` context, and the\n * `iframe.src` property is in the `RESOURCE_URL` context, which requires that values written to\n * this property are trusted as a `RESOURCE_URL`.\n *\n * This can be set explicitly by calling $sce.trustAs(type, value) on the value that is\n * trusted before passing it to the `ng-prop-*` directive. There are exist shorthand methods for\n * each context type in the form of {@link ng.$sce#trustAsResourceUrl $sce.trustAsResourceUrl()} et al.\n *\n * In some cases you can also rely upon automatic sanitization of untrusted values - see below.\n *\n * Based on the context, other options may exist to mark a value as trusted / configure the behavior\n * of {@link ng.$sce}. For example, to restrict the `RESOURCE_URL` context to specific origins, use\n * the {@link $sceDelegateProvider#trustedResourceUrlList trustedResourceUrlList()}\n * and {@link $sceDelegateProvider#bannedResourceUrlList bannedResourceUrlList()}.\n *\n * {@link ng.$sce#what-trusted-context-types-are-supported- Find out more about the different context types}.\n *\n * ### HTML Sanitization\n *\n * By default, `$sce` will throw an error if it detects untrusted HTML content, and will not bind the\n * content.\n * However, if you include the {@link ngSanitize ngSanitize module}, it will try to sanitize the\n * potentially dangerous HTML, e.g. strip non-trusted tags and attributes when binding to\n * `innerHTML`.\n *\n * @example\n * ### Binding to different contexts\n *\n * \n * \n * angular.module('exampleNgProp', [])\n * .component('main', {\n * templateUrl: 'main.html',\n * controller: function($sce) {\n * this.safeContent = 'Safe content';\n * this.unsafeContent = '';\n * this.trustedUnsafeContent = $sce.trustAsHtml(this.unsafeContent);\n * }\n * });\n * \n * \n *

\n *

\n * Binding to a property without security context:\n *

\n * innerText (safeContent)\n *

\n *\n *

\n * \"Safe\" content that requires a security context will throw because the contents could potentially be dangerous ...\n *

\n * innerHTML (safeContent)\n *

\n *\n *

\n * ... so that actually dangerous content cannot be executed:\n *

\n * innerHTML (unsafeContent)\n *

\n *\n *

An optional config can be passed as the\n * last argument.\n *\n * ```js\n * $http.get('/someUrl', config).then(successCallback, errorCallback);\n * $http.post('/someUrl', data, config).then(successCallback, errorCallback);\n * ```\n *\n * Complete list of shortcut methods:\n *\n * - {@link ng.$http#get $http.get}\n * - {@link ng.$http#head $http.head}\n * - {@link ng.$http#post $http.post}\n * - {@link ng.$http#put $http.put}\n * - {@link ng.$http#delete $http.delete}\n * - {@link ng.$http#jsonp $http.jsonp}\n * - {@link ng.$http#patch $http.patch}\n *\n *\n * ## Writing Unit Tests that use $http\n * When unit testing (using {@link ngMock ngMock}), it is necessary to call\n * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending\n * request using trained responses.\n *\n * ```\n * $httpBackend.expectGET(...);\n * $http.get(...);\n * $httpBackend.flush();\n * ```\n *\n * ## Setting HTTP Headers\n *\n * The $http service will automatically add certain HTTP headers to all requests. These defaults\n * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration\n * object, which currently contains this default configuration:\n *\n * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):\n * - Accept: application/json, text/plain, \\*/\\*\n * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)\n * - `Content-Type: application/json`\n * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)\n * - `Content-Type: application/json`\n *\n * To add or overwrite these defaults, simply add or remove a property from these configuration\n * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object\n * with the lowercased HTTP method name as the key, e.g.\n * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.\n *\n * The defaults can also be set at runtime via the `$http.defaults` object in the same\n * fashion. For example:\n *\n * ```\n * module.run(function($http) {\n * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w';\n * });\n * ```\n *\n * In addition, you can supply a `headers` property in the config object passed when\n * calling `$http(config)`, which overrides the defaults without changing them globally.\n *\n * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,\n * Use the `headers` property, setting the desired header to `undefined`. For example:\n *\n * ```js\n * var req = {\n * method: 'POST',\n * url: 'http://example.com',\n * headers: {\n * 'Content-Type': undefined\n * },\n * data: { test: 'test' }\n * }\n *\n * $http(req).then(function(){...}, function(){...});\n * ```\n *\n * ## Transforming Requests and Responses\n *\n * Both requests and responses can be transformed using transformation functions: `transformRequest`\n * and `transformResponse`. These properties can be a single function that returns\n * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,\n * which allows you to `push` or `unshift` a new transformation function into the transformation chain.\n *\n *

\n * **Note:** AngularJS does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.\n * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).\n * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest\n * function will be reflected on the scope and in any templates where the object is data-bound.\n * To prevent this, transform functions should have no side-effects.\n * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.\n *

\n *\n * ### Default Transformations\n *\n * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and\n * `defaults.transformResponse` properties. If a request does not provide its own transformations\n * then these will be applied.\n *\n * You can augment or replace the default transformations by modifying these properties by adding to or\n * replacing the array.\n *\n * AngularJS provides the following default transformations:\n *\n * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`) is\n * an array with one function that does the following:\n *\n * - If the `data` property of the request configuration object contains an object, serialize it\n * into JSON format.\n *\n * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`) is\n * an array with one function that does the following:\n *\n * - If XSRF prefix is detected, strip it (see Security Considerations section below).\n * - If the `Content-Type` is `application/json` or the response looks like JSON,\n * deserialize it using a JSON parser.\n *\n *\n * ### Overriding the Default Transformations Per Request\n *\n * If you wish to override the request/response transformations only for a single request then provide\n * `transformRequest` and/or `transformResponse` properties on the configuration object passed\n * into `$http`.\n *\n * Note that if you provide these properties on the config object the default transformations will be\n * overwritten. If you wish to augment the default transformations then you must include them in your\n * local transformation array.\n *\n * The following code demonstrates adding a new response transformation to be run after the default response\n * transformations have been run.\n *\n * ```js\n * function appendTransform(defaults, transform) {\n *\n * // We can't guarantee that the default transformation is an array\n * defaults = angular.isArray(defaults) ? defaults : [defaults];\n *\n * // Append the new transformation to the defaults\n * return defaults.concat(transform);\n * }\n *\n * $http({\n * url: '...',\n * method: 'GET',\n * transformResponse: appendTransform($http.defaults.transformResponse, function(value) {\n * return doTransform(value);\n * })\n * });\n * ```\n *\n *\n * ## Caching\n *\n * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must\n * set the config.cache value or the default cache value to TRUE or to a cache object (created\n * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes\n * precedence over the default cache value.\n *\n * In order to:\n * * cache all responses - set the default cache value to TRUE or to a cache object\n * * cache a specific response - set config.cache value to TRUE or to a cache object\n *\n * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,\n * then the default `$cacheFactory(\"$http\")` object is used.\n *\n * The default cache value can be set by updating the\n * {@link ng.$http#defaults `$http.defaults.cache`} property or the\n * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.\n *\n * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using\n * the relevant cache object. The next time the same request is made, the response is returned\n * from the cache without sending a request to the server.\n *\n * Take note that:\n *\n * * Only GET and JSONP requests are cached.\n * * The cache key is the request URL including search parameters; headers are not considered.\n * * Cached responses are returned asynchronously, in the same way as responses from the server.\n * * If multiple identical requests are made using the same cache, which is not yet populated,\n * one request will be made to the server and remaining requests will return the same response.\n * * A cache-control header on the response does not affect if or how responses are cached.\n *\n *\n * ## Interceptors\n *\n * Before you start creating interceptors, be sure to understand the\n * {@link ng.$q $q and deferred/promise APIs}.\n *\n * For purposes of global error handling, authentication, or any kind of synchronous or\n * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be\n * able to intercept requests before they are handed to the server and\n * responses before they are handed over to the application code that\n * initiated these requests. The interceptors leverage the {@link ng.$q\n * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.\n *\n * The interceptors are service factories that are registered with the `$httpProvider` by\n * adding them to the `$httpProvider.interceptors` array. The factory is called and\n * injected with dependencies (if specified) and returns the interceptor.\n *\n * There are two kinds of interceptors (and two kinds of rejection interceptors):\n *\n * * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to\n * modify the `config` object or create a new one. The function needs to return the `config`\n * object directly, or a promise containing the `config` or a new `config` object.\n * * `requestError`: interceptor gets called when a previous interceptor threw an error or\n * resolved with a rejection.\n * * `response`: interceptors get called with http `response` object. The function is free to\n * modify the `response` object or create a new one. The function needs to return the `response`\n * object directly, or as a promise containing the `response` or a new `response` object.\n * * `responseError`: interceptor gets called when a previous interceptor threw an error or\n * resolved with a rejection.\n *\n *\n * ```js\n * // register the interceptor as a service\n * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {\n * return {\n * // optional method\n * 'request': function(config) {\n * // do something on success\n * return config;\n * },\n *\n * // optional method\n * 'requestError': function(rejection) {\n * // do something on error\n * if (canRecover(rejection)) {\n * return responseOrNewPromise\n * }\n * return $q.reject(rejection);\n * },\n *\n *\n *\n * // optional method\n * 'response': function(response) {\n * // do something on success\n * return response;\n * },\n *\n * // optional method\n * 'responseError': function(rejection) {\n * // do something on error\n * if (canRecover(rejection)) {\n * return responseOrNewPromise\n * }\n * return $q.reject(rejection);\n * }\n * };\n * });\n *\n * $httpProvider.interceptors.push('myHttpInterceptor');\n *\n *\n * // alternatively, register the interceptor via an anonymous factory\n * $httpProvider.interceptors.push(function($q, dependency1, dependency2) {\n * return {\n * 'request': function(config) {\n * // same as above\n * },\n *\n * 'response': function(response) {\n * // same as above\n * }\n * };\n * });\n * ```\n *\n * ## Security Considerations\n *\n * When designing web applications, consider security threats from:\n *\n * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)\n * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)\n *\n * Both server and the client must cooperate in order to eliminate these threats. AngularJS comes\n * pre-configured with strategies that address these issues, but for this to work backend server\n * cooperation is required.\n *\n * ### JSON Vulnerability Protection\n *\n * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)\n * allows third party website to turn your JSON resource URL into\n * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To\n * counter this your server can prefix all JSON requests with following string `\")]}',\\n\"`.\n * AngularJS will automatically strip the prefix before processing it as JSON.\n *\n * For example if your server needs to return:\n * ```js\n * ['one','two']\n * ```\n *\n * which is vulnerable to attack, your server can return:\n * ```js\n * )]}',\n * ['one','two']\n * ```\n *\n * AngularJS will strip the prefix, before processing the JSON.\n *\n *\n * ### Cross Site Request Forgery (XSRF) Protection\n *\n * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by\n * which the attacker can trick an authenticated user into unknowingly executing actions on your\n * website. AngularJS provides a mechanism to counter XSRF. When performing XHR requests, the\n * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP\n * header (by default `X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read\n * the cookie, your server can be assured that the XHR came from JavaScript running on your\n * domain.\n *\n * To take advantage of this, your server needs to set a token in a JavaScript readable session\n * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the\n * server can verify that the cookie matches the `X-XSRF-TOKEN` HTTP header, and therefore be\n * sure that only JavaScript running on your domain could have sent the request. The token must\n * be unique for each user and must be verifiable by the server (to prevent the JavaScript from\n * making up its own tokens). We recommend that the token is a digest of your site's\n * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography))\n * for added security.\n *\n * The header will — by default — **not** be set for cross-domain requests. This\n * prevents unauthorized servers (e.g. malicious or compromised 3rd-party APIs) from gaining\n * access to your users' XSRF tokens and exposing them to Cross Site Request Forgery. If you\n * want to, you can trust additional origins to also receive the XSRF token, by adding them\n * to {@link ng.$httpProvider#xsrfTrustedOrigins xsrfTrustedOrigins}. This might be\n * useful, for example, if your application, served from `example.com`, needs to access your API\n * at `api.example.com`.\n * See {@link ng.$httpProvider#xsrfTrustedOrigins $httpProvider.xsrfTrustedOrigins} for\n * more details.\n *\n *

\n * **Warning**
\n * Only trusted origins that you have control over and make sure you understand the\n * implications of doing so.\n *

\n *\n * The name of the cookie and the header can be specified using the `xsrfCookieName` and\n * `xsrfHeaderName` properties of either `$httpProvider.defaults` at config-time,\n * `$http.defaults` at run-time, or the per-request config object.\n *\n * In order to prevent collisions in environments where multiple AngularJS apps share the\n * same domain or subdomain, we recommend that each application uses a unique cookie name.\n *\n *\n * @param {object} config Object describing the request to be made and how it should be\n * processed. The object has following properties:\n *\n * - **method** â `{string}` â HTTP method (e.g. 'GET', 'POST', etc)\n * - **url** â `{string|TrustedObject}` â Absolute or relative URL of the resource that is being requested;\n * or an object created by a call to `$sce.trustAsResourceUrl(url)`.\n * - **params** â `{Object.}` â Map of strings or objects which will be serialized\n * with the `paramSerializer` and appended as GET parameters.\n * - **data** â `{string|Object}` â Data to be sent as the request message data.\n * - **headers** â `{Object}` â Map of strings or functions which return strings representing\n * HTTP headers to send to the server. If the return value of a function is null, the\n * header will not be sent. Functions accept a config object as an argument.\n * - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.\n * To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.\n * The handler will be called in the context of a `$apply` block.\n * - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload\n * object. To bind events to the XMLHttpRequest object, use `eventHandlers`.\n * The handler will be called in the context of a `$apply` block.\n * - **xsrfHeaderName** â `{string}` â Name of HTTP header to populate with the XSRF token.\n * - **xsrfCookieName** â `{string}` â Name of cookie containing the XSRF token.\n * - **transformRequest** â\n * `{function(data, headersGetter)|Array.}` â\n * transform function or an array of such functions. The transform function takes the http\n * request body and headers and returns its transformed (typically serialized) version.\n * See {@link ng.$http#overriding-the-default-transformations-per-request\n * Overriding the Default Transformations}\n * - **transformResponse** â\n * `{function(data, headersGetter, status)|Array.}` â\n * transform function or an array of such functions. The transform function takes the http\n * response body, headers and status and returns its transformed (typically deserialized) version.\n * See {@link ng.$http#overriding-the-default-transformations-per-request\n * Overriding the Default Transformations}\n * - **paramSerializer** - `{string|function(Object):string}` - A function used to\n * prepare the string representation of request parameters (specified as an object).\n * If specified as string, it is interpreted as function registered with the\n * {@link $injector $injector}, which means you can create your own serializer\n * by registering it as a {@link auto.$provide#service service}.\n * The default serializer is the {@link $httpParamSerializer $httpParamSerializer};\n * alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}\n * - **cache** â `{boolean|Object}` â A boolean value or object created with\n * {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.\n * See {@link $http#caching $http Caching} for more information.\n * - **timeout** â `{number|Promise}` â timeout in milliseconds, or {@link ng.$q promise}\n * that should abort the request when resolved.\n *\n * A numerical timeout or a promise returned from {@link ng.$timeout $timeout}, will set\n * the `xhrStatus` in the {@link $http#$http-returns response} to \"timeout\", and any other\n * resolved promise will set it to \"abort\", following standard XMLHttpRequest behavior.\n *\n * - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the\n * XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)\n * for more information.\n * - **responseType** - `{string}` - see\n * [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).\n *\n * @returns {HttpPromise} A {@link ng.$q `Promise}` that will be resolved (request success)\n * or rejected (request failure) with a response object.\n *\n * The response object has these properties:\n *\n * - **data** â `{string|Object}` â The response body transformed with\n * the transform functions.\n * - **status** â `{number}` â HTTP status code of the response.\n * - **headers** â `{function([headerName])}` â Header getter function.\n * - **config** â `{Object}` â The configuration object that was used\n * to generate the request.\n * - **statusText** â `{string}` â HTTP status text of the response.\n * - **xhrStatus** â `{string}` â Status of the XMLHttpRequest\n * (`complete`, `error`, `timeout` or `abort`).\n *\n *\n * A response status code between 200 and 299 is considered a success status\n * and will result in the success callback being called. Any response status\n * code outside of that range is considered an error status and will result\n * in the error callback being called.\n * Also, status codes less than -1 are normalized to zero. -1 usually means\n * the request was aborted, e.g. using a `config.timeout`. More information\n * about the status might be available in the `xhrStatus` property.\n *\n * Note that if the response is a redirect, XMLHttpRequest will transparently\n * follow it, meaning that the outcome (success or error) will be determined\n * by the final response status code.\n *\n *\n * @property {Array.

The `expression` is evaluated against each item and the output is used\n * for comparing with other items.\n *\n * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in\n * ascending order.\n *\n * The comparison is done using the `comparator` function. If none is specified, a default, built-in\n * comparator is used (see below for details - in a nutshell, it compares numbers numerically and\n * strings alphabetically).\n *\n * ### Under the hood\n *\n * Ordering the specified `collection` happens in two phases:\n *\n * 1. All items are passed through the predicate (or predicates), and the returned values are saved\n * along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed\n * through a predicate that extracts the value of the `label` property, would be transformed to:\n * ```\n * {\n * value: 'foo',\n * type: 'string',\n * index: ...\n * }\n * ```\n * **Note:** `null` values use `'null'` as their type.\n * 2. The comparator function is used to sort the items, based on the derived values, types and\n * indices.\n *\n * If you use a custom comparator, it will be called with pairs of objects of the form\n * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal\n * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the\n * second, or `1` otherwise.\n *\n * In order to ensure that the sorting will be deterministic across platforms, if none of the\n * specified predicates can distinguish between two items, `orderBy` will automatically introduce a\n * dummy predicate that returns the item's index as `value`.\n * (If you are using a custom comparator, make sure it can handle this predicate as well.)\n *\n * If a custom comparator still can't distinguish between two items, then they will be sorted based\n * on their index using the built-in comparator.\n *\n * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted\n * value for an item, `orderBy` will try to convert that object to a primitive value, before passing\n * it to the comparator. The following rules govern the conversion:\n *\n * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be\n * used instead.
\n * (If the object has a `valueOf()` method that returns another object, then the returned object\n * will be used in subsequent steps.)\n * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that\n * returns a primitive, its return value will be used instead.
\n * (If the object has a `toString()` method that returns another object, then the returned object\n * will be used in subsequent steps.)\n * 3. No conversion; the object itself is used.\n *\n * ### The default comparator\n *\n * The default, built-in comparator should be sufficient for most usecases. In short, it compares\n * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to\n * using their index in the original collection, sorts values of different types by type and puts\n * `undefined` and `null` values at the end of the sorted list.\n *\n * More specifically, it follows these steps to determine the relative order of items:\n *\n * 1. If the compared values are of different types:\n * - If one of the values is undefined, consider it \"greater than\" the other.\n * - Else if one of the values is null, consider it \"greater than\" the other.\n * - Else compare the types themselves alphabetically.\n * 2. If both values are of type `string`, compare them alphabetically in a case- and\n * locale-insensitive way.\n * 3. If both values are objects, compare their indices instead.\n * 4. Otherwise, return:\n * - `0`, if the values are equal (by strict equality comparison, i.e. using `===`).\n * - `-1`, if the 1st value is \"less than\" the 2nd value (compared using the `<` operator).\n * - `1`, otherwise.\n *\n * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being\n * saved as numbers and not strings.\n * **Note:** For the purpose of sorting, `null` and `undefined` are considered \"greater than\"\n * any other value (with undefined \"greater than\" null). This effectively means that `null`\n * and `undefined` values end up at the end of a list sorted in ascending order.\n * **Note:** `null` values use `'null'` as their type to be able to distinguish them from objects.\n *\n * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort.\n * @param {(Function|string|Array.)=} expression - A predicate (or list of\n * predicates) to be used by the comparator to determine the order of elements.\n *\n * Can be one of:\n *\n * - `Function`: A getter function. This function will be called with each item as argument and\n * the return value will be used for sorting.\n * - `string`: An AngularJS expression. This expression will be evaluated against each item and the\n * result will be used for sorting. For example, use `'label'` to sort by a property called\n * `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label`\n * property.
\n * (The result of a constant expression is interpreted as a property name to be used for\n * comparison. For example, use `'\"special name\"'` (note the extra pair of quotes) to sort by a\n * property called `special name`.)
\n * An expression can be optionally prefixed with `+` or `-` to control the sorting direction,\n * ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided,\n * (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons.\n * - `Array`: An array of function and/or string predicates. If a predicate cannot determine the\n * relative order of two items, the next predicate is used as a tie-breaker.\n *\n * **Note:** If the predicate is missing or empty then it defaults to `'+'`.\n *\n * @param {boolean=} reverse - If `true`, reverse the sorting order.\n * @param {(Function)=} comparator - The comparator function used to determine the relative order of\n * value pairs. If omitted, the built-in comparator will be used.\n *\n * @returns {Array} - The sorted array.\n *\n *\n * @example\n * ### Ordering a table with `ngRepeat`\n *\n * The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by\n * age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means\n * it defaults to the built-in comparator.\n *\n \n \n

This means that the outer form is valid when all of the child\n * forms are valid as well. However, browsers do not allow nesting of `` elements, so\n * AngularJS provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to\n * `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group\n * of controls needs to be determined.\n *\n * ## CSS classes\n * - `ng-valid` is set if the form is valid.\n * - `ng-invalid` is set if the form is invalid.\n * - `ng-pending` is set if the form is pending.\n * - `ng-pristine` is set if the form is pristine.\n * - `ng-dirty` is set if the form is dirty.\n * - `ng-submitted` is set if the form was submitted.\n *\n * Keep in mind that ngAnimate can detect each of these classes when added and removed.\n *\n *\n * ## Submitting a form and preventing the default action\n *\n * Since the role of forms in client-side AngularJS applications is different than in classical\n * roundtrip apps, it is desirable for the browser not to translate the form submission into a full\n * page reload that sends the data to the server. Instead some javascript logic should be triggered\n * to handle the form submission in an application-specific way.\n *\n * For this reason, AngularJS prevents the default action (form submission to the server) unless the\n * `` element has an `action` attribute specified.\n *\n * You can use one of the following two ways to specify what javascript method should be called when\n * a form is submitted:\n *\n * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element\n * - {@link ng.directive:ngClick ngClick} directive on the first\n * button or input field of type submit (input[type=submit])\n *\n * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}\n * or {@link ng.directive:ngClick ngClick} directives.\n * This is because of the following form submission rules in the HTML specification:\n *\n * - If a form has only one input field then hitting enter in this field triggers form submit\n * (`ngSubmit`)\n * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter\n * doesn't trigger submit\n * - if a form has one or more input fields and one or more buttons or input[type=submit] then\n * hitting enter in any of the input fields will trigger the click handler on the *first* button or\n * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)\n *\n * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is\n * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`\n * to have access to the updated model.\n *\n * @animations\n * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.\n * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any\n * other validations that are performed within the form. Animations in ngForm are similar to how\n * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well\n * as JS animations.\n *\n * The following example shows a simple way to utilize CSS transitions to style a form element\n * that has been rendered as invalid after it has been validated:\n *\n *

\n * //be sure to include ngAnimate as a module to hook into more\n * //advanced animations\n * .my-form {\n *   transition:0.5s linear all;\n *   background: white;\n * }\n * .my-form.ng-invalid {\n *   background: red;\n *   color:white;\n * }\n *

Model binding,\n * validation and number parsing are nevertheless supported.\n *\n * Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]`\n * in a way that never allows the input to hold an invalid value. That means:\n * - any non-numerical value is set to `(max + min) / 2`.\n * - any numerical value that is less than the current min val, or greater than the current max val\n * is set to the min / max val respectively.\n * - additionally, the current `step` is respected, so the nearest value that satisfies a step\n * is used.\n *\n * See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range))\n * for more info.\n *\n * This has the following consequences for AngularJS:\n *\n * Since the element value should always reflect the current model value, a range input\n * will set the bound ngModel expression to the value that the browser has set for the\n * input element. For example, in the following input ``,\n * if the application sets `model.value = null`, the browser will set the input to `'50'`.\n * AngularJS will then set the model to `50`, to prevent input and model value being out of sync.\n *\n * That means the model for range will immediately be set to `50` after `ngModel` has been\n * initialized. It also means a range input can never have the required error.\n *\n * This does not only affect changes to the model value, but also to the values of the `min`,\n * `max`, and `step` attributes. When these change in a way that will cause the browser to modify\n * the input value, AngularJS will also update the model value.\n *\n * Automatic value adjustment also means that a range input element can never have the `required`,\n * `min`, or `max` errors.\n *\n * However, `step` is currently only fully implemented by Firefox.

When used together with {@link ngModel `ngModel`}, it provides data-binding,\n * input state control, and validation.\n * Input control follows HTML5 input types and polyfills the HTML5 validation behavior for older browsers.\n *\n * <div class=\"alert alert-warning\">\n * **Note:** Not every feature offered is available for all input types.\n * Specifically, data binding and event handling via `ng-model` is unsupported for `input[file]`.\n * </div>\n *\n * @param {string} ngModel Assignable AngularJS expression to data-bind to.\n * @param {string=} name Property name of the form under which the control is published.\n * @param {string=} required Sets `required` validation error key if the value is not entered.\n * @param {boolean=} ngRequired Sets `required` attribute if set to true\n * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than\n *    minlength.\n * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than\n *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of any\n *    length.\n * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}\n *    value does not match a RegExp found by evaluating the AngularJS expression given in the attribute value.\n *    If the expression evaluates to a RegExp object, then this is used directly.\n *    If the expression evaluates to a string, then it will be converted to a RegExp\n *    after wrapping it in `^` and `$` characters. For instance, `\"abc\"` will be converted to\n *    `new RegExp('^abc$')`.<br />\n *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to\n *    start at the index of the last search's match, thus not taking the whole input value into\n *    account.\n * @param {string=} ngChange AngularJS expression to be executed when input changes due to user\n *    interaction with the input element.\n * @param {boolean=} [ngTrim=true] If set to false AngularJS will not automatically trim the input.\n *    This parameter is ignored for input[type=password]

If the expression evaluates to a string, the string should be one or more space-delimited class\n * names.\n *\n * 2. If the expression evaluates to an object, then for each key-value pair of the\n * object with a truthy value the corresponding key is used as a class name.\n *\n * 3. If the expression evaluates to an array, each element of the array should either be a string as in\n * type 1 or an object as in type 2. This means that you can mix strings and objects together in an array\n * to give you more control over what CSS classes appear. See the code below for an example of this.\n *\n *\n * The directive won't add duplicate classes if a particular class was already set.\n *\n * When the expression changes, the previously added classes are removed and only then are the\n * new classes added.\n *\n * @knownIssue\n * You should not use {@link guide/interpolation interpolation} in the value of the `class`\n * attribute, when using the `ngClass` directive on the same element.\n * See {@link guide/interpolation#known-issues here} for more info.\n *\n * @animations\n * | Animation                        | Occurs                              |\n * |----------------------------------|-------------------------------------|\n * | {@link ng.$animate#addClass addClass}       | just before the class is applied to the element   |\n * | {@link ng.$animate#removeClass removeClass} | just before the class is removed from the element |\n * | {@link ng.$animate#setClass setClass} | just before classes are added and classes are removed from the element at the same time |\n *\n * ### ngClass and pre-existing CSS3 Transitions/Animations\n   The ngClass directive still supports CSS3 Transitions/Animations even if they do not follow the ngAnimate CSS naming structure.\n   Upon animation ngAnimate will apply supplementary CSS classes to track the start and end of an animation, but this will not hinder\n   any pre-existing CSS transitions already on the element. To get an idea of what happens during a class-based animation, be sure\n   to view the step by step details of {@link $animate#addClass $animate.addClass} and\n   {@link $animate#removeClass $animate.removeClass}.\n *\n * @param {expression} ngClass {@link guide/expression Expression} to eval. The result\n *   of the evaluation can be a string representing space delimited class\n *   names, an array, or a map of class names to boolean values. In the case of a map, the\n *   names of the properties whose values are truthy will be added as css classes to the\n *   element.\n *\n * @example\n * ### Basic\n   <example name=\"ng-class\">\n

This is a key aspect of how angular\n * supports the principles behind the Model-View-Controller design pattern.\n *\n * MVC components in angular:\n *\n * * Model â Models are the properties of a scope; scopes are attached to the DOM where scope properties\n *   are accessed through bindings.\n * * View â The template (HTML with data bindings) that is rendered into the View.\n * * Controller â The `ngController` directive specifies a Controller class; the class contains business\n *   logic behind the application to decorate the scope with functions and values\n *\n * Note that you can also attach controllers to the DOM by declaring it in a route definition\n * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller\n * again using `ng-controller` in the template itself.  This will cause the controller to be attached\n * and executed twice.\n *\n * @element ANY\n * @scope\n * @priority 500\n * @param {expression} ngController Name of a constructor function registered with the current\n * {@link ng.$controllerProvider $controllerProvider} or an {@link guide/expression expression}\n * that on the current scope evaluates to a constructor function.\n *\n * The controller instance can be published into a scope property by specifying\n * `ng-controller=\"as propertyName\"`.\n *\n * @example\n * Here is a simple form for editing user contact information. Adding, removing, clearing, and\n * greeting are methods declared on the controller (see source tab). These methods can\n * easily be called from the AngularJS markup. Any changes to the data are automatically reflected\n * in the View without the need for a manual update.\n *\n * Two different declaration styles are included below:\n *\n * * one binds methods and properties directly onto the controller using `this`:\n * `ng-controller=\"SettingsController1 as settings\"`\n * * one injects `$scope` into the controller:\n * `ng-controller=\"SettingsController2\"`\n *\n * The second option is more common in the AngularJS community, and is generally used in boilerplates\n * and in this guide. However, there are advantages to binding properties directly to the controller\n * and avoiding scope.\n *\n * * Using `controller as` makes it obvious which controller you are accessing in the template when\n * multiple controllers apply to an element.\n * * If you are writing your controllers as classes you have easier access to the properties and\n * methods, which will appear on the scope, from inside the controller code.\n * * Since there is always a `.` in the bindings, you don't have to worry about prototypal\n * inheritance masking primitives.\n *\n * This example demonstrates the `controller as` syntax.\n *\n * <example name=\"ngControllerAs\" module=\"controllerAsExample\">\n *   <file name=\"index.html\">\n *    <div id=\"ctrl-as-exmpl\"

@ngdoc directive\n * @name ngCsp\n *\n * @restrict A\n * @element ANY\n * @description\n *\n * AngularJS has some features that can conflict with certain restrictions that are applied when using\n * [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) rules.\n *\n * If you intend to implement CSP with these rules then you must tell AngularJS not to use these\n * features.\n *\n * This is necessary when developing things like Google Chrome Extensions or Universal Windows Apps.\n *\n *\n * The following default rules in CSP affect AngularJS:\n *\n * * The use of `eval()`, `Function(string)` and similar functions to dynamically create and execute\n * code from strings is forbidden. AngularJS makes use of this in the {@link $parse} service to\n * provide a 30% increase in the speed of evaluating AngularJS expressions. (This CSP rule can be\n * disabled with the CSP keyword `unsafe-eval`, but it is generally not recommended as it would\n * weaken the protections offered by CSP.)\n *\n * * The use of inline resources, such as inline `<script>` and `<style>` elements, are forbidden.\n * This prevents apps from injecting custom styles directly into the document. AngularJS makes use of\n * this to include some CSS rules (e.g. {@link ngCloak} and {@link ngHide}). To make these\n * directives work when a CSP rule is blocking inline styles, you must link to the `angular-csp.css`\n * in your HTML manually. (This CSP rule can be disabled with the CSP keyword `unsafe-inline`, but\n * it is generally not recommended as it would weaken the protections offered by CSP.)\n *\n * If you do not provide `ngCsp` then AngularJS tries to autodetect if CSP is blocking dynamic code\n * creation from strings (e.g., `unsafe-eval` not specified in CSP header) and automatically\n * deactivates this feature in the {@link $parse} service. This autodetection, however, triggers a\n * CSP error to be logged in the console:\n *\n * ```\n * Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of\n * script in the following Content Security Policy directive: \"default-src 'self'\". Note that\n * 'script-src' was not explicitly set, so 'default-src' is used as a fallback.\n * ```\n *\n * This error is harmless but annoying. To prevent the error from showing up, put the `ngCsp`\n * directive on an element of the HTML document that appears before the `<script>` tag that loads\n * the `angular.js` file.\n *\n * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*\n *\n * You can specify which of the CSP related AngularJS features should be deactivated by providing\n * a value for the `ng-csp` attribute. The options are as follows:\n *\n * * no-inline-style: this stops AngularJS from injecting CSS styles into the DOM\n *\n * * no-unsafe-eval: this stops AngularJS from optimizing $parse with unsafe eval of strings\n *\n * You can use these values in the following combinations:\n *\n *\n * * No declaration means that AngularJS will assume that you can do inline styles, but it will do\n * a runtime check for unsafe-eval. E.g. `<body>`. This is backwardly compatible with previous\n * versions of AngularJS.\n *\n * * A simple `ng-csp` (or `data-ng-csp`) attribute will tell AngularJS to deactivate both inline\n * styles and unsafe eval. E.g. `<body ng-csp>`. This is backwardly compatible with previous\n * versions of AngularJS.\n *\n * * Specifying only `no-unsafe-eval` tells AngularJS that we must not use eval, but that we can\n * inject inline styles. E.g. `<body ng-csp=\"no-unsafe-eval\">`.\n *\n * * Specifying only `no-inline-style` tells AngularJS that we must not inject styles, but that we can\n * run eval - no automatic check for unsafe eval will occur. E.g. `<body ng-csp=\"no-inline-style\">`\n *\n * * Specifying both `no-unsafe-eval` and `no-inline-style` tells AngularJS that we must not inject\n * styles nor use eval, which is the same as an empty: ng-csp.\n * E.g.`<body ng-csp=\"no-inline-style;no-unsafe-eval\">`\n *\n * @example\n *\n * This example shows how to apply the `ngCsp` directive to the `html` tag.\n   ```html\n     <!doctype html>\n     <html ng-app ng-csp>\n     ...\n     ...\n     </html>\n   ```\n\n  \n  <example name=\"example.csp\" module=\"cspExample\" ng-csp=\"true\">\n    <file name=\"index.html\">\n      <div ng-controller=\"MainController as ctrl\">\n        <div>\n          <button ng-click=\"ctrl.inc()\" id=\"inc\">Increment</button>\n          <span id=\"counter\">\n            {{ctrl.counter}}\n          </span>\n        </div>\n\n        <div>\n          <button ng-click=\"ctrl.evil()\" id=\"evil\">Evil</button>\n          <span id=\"evilError\">\n            {{ctrl.evilError}}\n          </span>\n        </div>\n      </div>\n    </file>\n    <file name=\"script.js\">\n       angular.module('cspExample', [])\n         .controller('MainController', function MainController() {\n            this.counter = 0;\n            this.inc = function() {\n              this.counter++;\n            };\n            this.evil = function() {\n              try {\n                eval('1+2'); // eslint-disable-line no-eval\n              } catch (e) {\n                this.evilError = e.message;\n              }\n            };\n          });\n    </file>\n    <file name=\"protractor.js\" type=\"protractor\">\n      var util, webdriver;\n\n      var incBtn = element(by.id('inc'));\n      var counter = element(by.id('counter'));\n      var evilBtn = element(by.id('evil'));\n      var evilError = element(by.id('evilError'));\n\n      function getAndClearSevereErrors() {\n        return browser.manage().logs().get('browser').then(function(browserLog) {\n          return browserLog.filter(function(logEntry) {\n            return logEntry.level.value > webdriver.logging.Level.WARNING.value;\n          });\n        });\n      }\n\n      function clearErrors() {\n        getAndClearSevereErrors();\n      }\n\n      function expectNoErrors() {\n        getAndClearSevereErrors().then(function(filteredLog) {\n          expect(filteredLog.length).toEqual(0);\n          if (filteredLog.length) {\n            console.log('browser console errors: ' + util.inspect(filteredLog));\n          }\n        });\n      }\n\n      function expectError(regex) {\n        getAndClearSevereErrors().then(function(filteredLog) {\n          var found = false;\n          filteredLog.forEach(function(log) {\n            if (log.message.match(regex)) {\n              found = true;\n            }\n          });\n          if (!found) {\n            throw new Error('expected an error that matches ' + regex);\n          }\n        });\n      }\n\n      beforeEach(function() {\n        util = require('util');\n        webdriver = require('selenium-webdriver');\n      });\n\n      // For now, we only test on Chrome,\n      // as Safari does not load the page with Protractor's injected scripts,\n      // and Firefox webdriver always disables content security policy (#6358)\n      if (browser.params.browser !== 'chrome') {\n        return;\n      }\n\n      it('should not report errors when the page is loaded', function() {\n        // clear errors so we are not dependent on previous tests\n        clearErrors();\n        // Need to reload the page as the page is already loaded when\n        // we come here\n        browser.driver.getCurrentUrl().then(function(url) {\n          browser.get(url);\n        });\n        expectNoErrors();\n      });\n\n      it('should evaluate expressions', function() {\n        expect(counter.getText()).toEqual('0');\n        incBtn.click();\n        expect(counter.getText()).toEqual('1');\n        expectNoErrors();\n      });\n\n      it('should throw and report an error when using \"eval\"', function() {\n        evilBtn.click();\n        expect(evilError.getText()).toMatch(/Content Security Policy/);\n        expectError(/Content Security Policy/);\n      });\n    </file>\n  </example>\n  */\n\n// `ngCsp` is not implemented as a proper directive any more, because we need it be processed while\n// we bootstrap the app (before `$parse` is instantiated).

If the expression assigned to `ngIf` evaluates to a false\n * value then the element is removed from the DOM, otherwise a clone of the\n * element is reinserted into the DOM.\n *\n * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the\n * element in the DOM rather than changing its visibility via the `display` css property.  A common\n * case when this difference is significant is when using css selectors that rely on an element's\n * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.\n *\n * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope\n * is created when the element is restored.  The scope created within `ngIf` inherits from\n * its parent scope using\n * [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance).\n * An important implication of this is if `ngModel` is used within `ngIf` to bind to\n * a javascript primitive defined in the parent scope. In this case any modifications made to the\n * variable within the child scope will override (hide) the value in the parent scope.\n *\n * Also, `ngIf` recreates elements using their compiled state. An example of this behavior\n * is if an element's class attribute is directly modified after it's compiled, using something like\n * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element\n * the added class will be lost because the original compiled state is used to regenerate the element.\n *\n * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`\n * and `leave` effects.\n *\n * @animations\n * | Animation                        | Occurs                               |\n * |----------------------------------|-------------------------------------|\n * | {@link ng.$animate#enter enter}  | just after the `ngIf` contents change and a new DOM element is created and injected into the `ngIf` container |\n * | {@link ng.$animate#leave leave}  | just before the `ngIf` contents are removed from the DOM |\n *\n * @element ANY\n * @scope\n * @priority 600\n * @param {expression} ngIf If the {@link guide/expression expression} is falsy then\n *     the element is removed from the DOM tree.

This implies that the user of the directive is responsible for\n *   dealing with whitespace but also allows you to use whitespace as a delimiter, such as a\n *   tab or newline character.\n * * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected\n *   when joining the list items back together) and whitespace around each list item is stripped\n *   before it is added to the model.\n *\n * @example\n * ### Validation\n *\n * <example name=\"ngList-directive\" module=\"listExample\">\n *   <file name=\"app.js\">\n *      angular.module('listExample', [])\n *        .controller('ExampleController', ['$scope', function($scope) {\n *          $scope.names = ['morpheus', 'neo', 'trinity'];\n *        }]);\n *   </file>\n *   <file name=\"index.html\">\n *    <form name=\"myForm\" ng-controller=\"ExampleController\">\n *      <label>List: <input name=\"namesInput\" ng-model=\"names\" ng-list required></label>\n *      <span role=\"alert\">\n *        <span class=\"error\" ng-show=\"myForm.namesInput.$error.required\">\n *        Required!</span>\n *      </span>\n *      <br>\n *      <tt>names = {{names}}</tt><br/>\n *      <tt>myForm.namesInput.$valid = {{myForm.namesInput.$valid}}</tt><br/>\n *      <tt>myForm.namesInput.$error = {{myForm.namesInput.$error}}</tt><br/>\n *      <tt>myForm.$valid = {{myForm.$valid}}</tt><br/>\n *      <tt>myForm.$error.required = {{!!myForm.$error.required}}</tt><br/>\n *     </form>\n *   </file>\n *   <file name=\"protractor.js\" type=\"protractor\">\n *     var listInput = element(by.model('names'));\n *     var names = element(by.exactBinding('names'));\n *     var valid = element(by.binding('myForm.namesInput.$valid'));\n *     var error = element(by.css('span.error'));\n *\n *     it('should initialize to model', function() {\n *       expect(names.getText()).toContain('[\"morpheus\",\"neo\",\"trinity\"]');\n *       expect(valid.getText()).toContain('true');\n *       expect(error.getCssValue('display')).toBe('none');\n *     });\n *\n *     it('should be invalid if empty', function() {\n *       listInput.clear();\n *       listInput.sendKeys('');\n *\n *       expect(names.getText()).toContain('');\n *       expect(valid.getText()).toContain('false');\n *       expect(error.getCssValue('display')).not.toBe('none');\n *     });\n *   </file>\n * </example>\n *\n * @example\n * ### Splitting on newline\n *\n * <example name=\"ngList-directive-newlines\">\n *   <file name=\"index.html\">\n *    <textarea ng-model=\"list\" ng-list=\"

\n *

Type something in the input. You will see that the model is not yet updated
Press the Escape key.\n *
1. In the first example, nothing happens, because the model is already '', and no\n * update is detected. If you blur the input, the model will be set to the current view.\n *

After this, the `$validators` and\n * `$asyncValidators` are called and the value is applied to `$modelValue`.\n * Finally, the value is set to the **expression** specified in the `ng-model` attribute and\n * all the registered change listeners, in the `$viewChangeListeners` list are called.\n *\n * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`\n * and the `default` trigger is not listed, all those actions will remain pending until one of the\n * `updateOn` events is triggered on the DOM element.\n * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}\n * directive is used with a custom debounce for this particular event.\n * Note that a `$digest` is only triggered once the `updateOn` events are fired, or if `debounce`\n * is specified, once the timer runs out.\n *\n * When used with standard inputs, the view value will always be a string (which is in some cases\n * parsed into another type, such as a `Date` object for `input[date]`.)\n * However, custom controls might also pass objects to this method. In this case, we should make\n * a copy of the object before passing it to `$setViewValue`. This is because `ngModel` does not\n * perform a deep watch of objects, it only looks for a change of identity.

If the property doesn't already exist on this scope, it will be created\n * implicitly and added to the scope.\n *\n * For best practices on using `ngModel`, see:\n *\n * - [Understanding Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes)\n *\n * For basic examples, how to use `ngModel`, see:\n *\n * - {@link ng.directive:input input}\n * - {@link input[text] text}\n * - {@link input[checkbox] checkbox}\n * - {@link input[radio] radio}\n * - {@link input[number] number}\n * - {@link input[email] email}\n * - {@link input[url] url}\n * - {@link input[date] date}\n * - {@link input[datetime-local] datetime-local}\n * - {@link input[time] time}\n * - {@link input[month] month}\n * - {@link input[week] week}\n * - {@link ng.directive:select select}\n * - {@link ng.directive:textarea textarea}\n *\n * ## Complex Models (objects or collections)\n *\n * By default, `ngModel` watches the model by reference, not value. This is important to know when\n * binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the\n * object or collection change, `ngModel` will not be notified and so the input will not be re-rendered.\n *\n * The model must be assigned an entirely new object or collection before a re-rendering will occur.\n *\n * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression\n * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or\n * if the select is given the `multiple` attribute.\n *\n * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the\n * first level of the object (or only changing the properties of an item in the collection if it's an array) will still\n * not trigger a re-rendering of the model.\n *\n * ## CSS classes\n * The following CSS classes are added and removed on the associated input/select/textarea element\n * depending on the validity of the model.\n *\n * - `ng-valid`: the model is valid\n * - `ng-invalid`: the model is invalid\n * - `ng-valid-[key]`: for each valid key added by `$setValidity`\n * - `ng-invalid-[key]`: for each invalid key added by `$setValidity`\n * - `ng-pristine`: the control hasn't been interacted with yet\n * - `ng-dirty`: the control has been interacted with\n * - `ng-touched`: the control has been blurred\n * - `ng-untouched`: the control hasn't been blurred\n * - `ng-pending`: any `$asyncValidators` are unfulfilled\n * - `ng-empty`: the view does not contain a value or the value is deemed \"empty\", as defined\n * by the {@link ngModel.NgModelController#$isEmpty} method\n * - `ng-not-empty`: the view contains a non-empty value\n *\n * Keep in mind that ngAnimate can detect each of these classes when added and removed.\n *\n * @animations\n * Animations within models are triggered when any of the associated CSS classes are added and removed\n * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,\n * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.\n * The animations that are triggered within ngModel are similar to how they work in ngClass and\n * animations can be hooked into using CSS transitions, keyframes as well as JS animations.\n *\n * The following example shows a simple way to utilize CSS transitions to style an input element\n * that has been rendered as invalid after it has been validated:\n *\n *

\n * //be sure to include ngAnimate as a module to hook into more\n * //advanced animations\n * .my-input {\n *   transition:0.5s linear all;\n *   background: white;\n * }\n * .my-input.ng-invalid {\n *   background: red;\n *   color:white;\n * }\n *

\n *\n * @example\n * ### Basic Usage\n * \n \n \n \n

\n Update input to see transitions when valid/invalid.\n Integer is a valid value.\n

\n \n \n * \n *\n * @example\n * ### Binding to a getter/setter\n *\n * Sometimes it's helpful to bind `ngModel` to a getter/setter function. A getter/setter is a\n * function that returns a representation of the model when called with zero arguments, and sets\n * the internal state of a model when called with an argument. It's sometimes useful to use this\n * for models that have an internal representation that's different from what the model exposes\n * to the view.\n *\n *

\n * **Best Practice:** It's best to keep getters fast because AngularJS is likely to call them more\n * frequently than other parts of your code.\n *

\n *\n * You use this behavior by adding `ng-model-options=\"{ getterSetter: true }\"` to an element that\n * has `ng-model` attached to it. You can also add `ng-model-options=\"{ getterSetter: true }\"` to\n * a `

`, which will enable this behavior for all ``s within it. See\n * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.\n *\n * The following example shows how to use `ngModel` with a getter/setter:\n *\n * @example\n * \n \n

\n \n Name:\n \n \n \n

user.name =

\n \n \n angular.module('getterSetterExample', [])\n .controller('ExampleController', ['$scope', function($scope) {\n var _name = 'Brian';\n $scope.user = {\n name: function(newName) {\n // Note that newName can be undefined for two reasons:\n // 1.

You can specify an `ngModelOptions` directive on any element. All {@link ngModel}\n * directives will use the options of their nearest `ngModelOptions` ancestor.\n *\n * The `ngModelOptions` settings are found by evaluating the value of the attribute directive as\n * an AngularJS expression. This expression should evaluate to an object, whose properties contain\n * the settings. For example: `

\n * \n *

\n * ```\n *\n * the `input` element will have the following settings\n *\n * ```js\n * { allowInvalid: true, updateOn: 'default', debounce: 0 }\n * ```\n *\n * Notice that the `debounce` setting was not inherited and used the default value instead.\n *\n * You can specify that all undefined settings are automatically inherited from an ancestor by\n * including a property with key of `\"*\"` and value of `\"$inherit\"`.\n *\n * For example given the following fragment of HTML\n *\n *\n * ```html\n *

\n * \n *

\n * ```\n *\n * the `input` element will have the following settings\n *\n * ```js\n * { allowInvalid: true, updateOn: 'default', debounce: 200 }\n * ```\n *\n * Notice that the `debounce` setting now inherits the value from the outer `

` element.\n *\n * If you are creating a reusable component then you should be careful when using `\"*\": \"$inherit\"`\n * since you may inadvertently inherit a setting in the future that changes the behavior of your component.\n *\n *\n * ## Triggering and debouncing model updates\n *\n * The `updateOn` and `debounce` properties allow you to specify a custom list of events that will\n * trigger a model update and/or a debouncing delay so that the actual update only takes place when\n * a timer expires; this timer will be reset after another change takes place.\n *\n * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might\n * be different from the value in the actual model. This means that if you update the model you\n * should also invoke {@link ngModel.NgModelController#$rollbackViewValue} on the relevant input field in\n * order to make sure it is synchronized with the model and that any debounced action is canceled.\n *\n * The easiest way to reference the control's {@link ngModel.NgModelController#$rollbackViewValue}\n * method is by making sure the input is placed inside a form that has a `name` attribute. This is\n * important because `form` controllers are published to the related scope under the name in their\n * `name` attribute.\n *\n * Any pending changes will take place immediately when an enclosing form is submitted via the\n * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`\n * to have access to the updated model.\n *\n * ### Overriding immediate updates\n *\n * The following example shows how to override immediate updates. Changes on the inputs within the\n * form will update the model only when the control loses focus (blur event). If `escape` key is\n * pressed while the input field is focused, the value is reset to the value in the current model.\n *\n * \n * \n *

Every event that is not listed\n * in `updateOn` is considered a \"default\" event, since different control types have different\n * default events.\n *\n * The control in this example updates by \"default\", \"click\", and \"blur\", with different `debounce`\n * values. You can see that \"click\" doesn't have an individual `debounce` value -\n * therefore it uses the `*` debounce value.\n *\n * There is also a button that calls {@link ngModel.NgModelController#$setViewValue $setViewValue}\n * directly with a \"custom\" event. Since \"custom\" is not defined in the `updateOn` list,\n * it is considered a \"default\" event and will update the\n * control if \"default\" is defined in `updateOn`, and will receive the \"default\" debounce value.\n * Note that this is just to illustrate how custom controls would possibly call `$setViewValue`.\n *\n * You can change the `updateOn` and `debounce` configuration to test different scenarios. This\n * is done with {@link ngModel.NgModelController#$overrideModelOptions $overrideModelOptions}.\n *\n \n \n \n \n \n angular.module('optionsExample', [])\n .component('modelUpdateDemo', {\n templateUrl: 'template.html',\n controller: function() {\n this.name = 'Chinua';\n\n this.options = {\n updateOn: 'default blur click',\n debounce: {\n default: 2000,\n blur: 0,\n '*': 1000\n }\n };\n\n this.updateEvents = function() {\n var eventList = this.options.updateOn.split(' ');\n eventList.push('*');\n var events = {};\n\n for (var i = 0; i < eventList.length; i++) {\n events[eventList[i]] = this.options.debounce[eventList[i]];\n }\n\n this.events = events;\n };\n\n this.updateOptions = function() {\n var options = angular.extend(this.options, {\n updateOn: Object.keys(this.events).join(' ').replace('*', ''),\n debounce: this.events\n });\n\n this.form.input.$overrideModelOptions(options);\n };\n\n // Initialize the event form\n this.updateEvents();\n }\n });\n \n \n \n Model: {{$ctrl.name}}\n

\n \n \n *\n *\n * ## Model updates and validation\n *\n * The default behaviour in `ngModel` is that the model value is set to `undefined` when the\n * validation determines that the value is invalid. By setting the `allowInvalid` property to true,\n * the model will still be updated even if the value is invalid.\n *\n *\n * ## Connecting to the scope\n *\n * By setting the `getterSetter` property to true you are telling ngModel that the `ngModel` expression\n * on the scope refers to a \"getter/setter\" function rather than the value itself.\n *\n * The following example shows how to bind to getter/setters:\n *\n * \n * \n *

\n * \n *

user.name =

\n *

\n * \n * \n * angular.module('getterSetterExample', [])\n * .controller('ExampleController', ['$scope', function($scope) {\n * var _name = 'Brian';\n * $scope.user = {\n * name: function(newName) {\n * return angular.isDefined(newName) ? (_name = newName) : _name;\n * }\n * };\n * }]);\n * \n * \n *\n *\n * ## Programmatically changing options\n *\n * The `ngModelOptions` expression is only evaluated once when the directive is linked; it is not\n * watched for changes. However, it is possible to override the options on a single\n * {@link ngModel.NgModelController} instance with\n * {@link ngModel.NgModelController#$overrideModelOptions `NgModelController#$overrideModelOptions()`}.\n * See also the example for\n * {@link ngModelOptions#default-events-extra-triggers-and-catch-all-debounce-values\n * Default events, extra triggers, and catch-all debounce values}.\n *\n *\n * ## Specifying timezones\n *\n * You can specify the timezone that date/time input directives expect by providing its name in the\n * `timezone` property.\n *\n *\n * ## Formatting the value of `time` and `datetime-local`\n *\n * With the options `timeSecondsFormat` and `timeStripZeroSeconds` it is possible to adjust the value\n * that is displayed in the control. Note that browsers may apply their own formatting\n * in the user interface.\n *\n \n \n \n \n \n angular.module('timeExample', [])\n .component('timeExample', {\n templateUrl: 'timeExample.html',\n controller: function() {\n this.time = new Date(1970, 0, 1, 14, 57, 0);\n\n this.options = {\n timeSecondsFormat: 'ss',\n timeStripZeroSeconds: true\n };\n\n this.optionChange = function() {\n this.timeForm.timeFormatted.$overrideModelOptions(this.options);\n this.time = new Date(this.time);\n };\n }\n });\n \n \n

\n * \n *\n * @param {Object} ngModelOptions options to apply to {@link ngModel} directives on this element and\n * and its descendents.\n *\n * **General options**:\n *\n * - `updateOn`: string specifying which event should the input be bound to. You can set several\n * events using an space delimited list. There is a special event called `default` that\n * matches the default events belonging to the control. These are the events that are bound to\n * the control, and when fired, update the `$viewValue` via `$setViewValue`.\n *\n * `ngModelOptions` considers every event that is not listed in `updateOn` a \"default\" event,\n * since different control types use different default events.\n *\n * See also the section {@link ngModelOptions#triggering-and-debouncing-model-updates\n * Triggering and debouncing model updates}.\n *\n * - `debounce`: integer value which contains the debounce model update value in milliseconds. A\n * value of 0 triggers an immediate update. If an object is supplied instead, you can specify a\n * custom value for each event. For example:\n * ```\n * ng-model-options=\"{\n * updateOn: 'default blur',\n * debounce: { 'default': 500, 'blur': 0 }\n * }\"\n * ```\n * You can use the `*` key to specify a debounce value that applies to all events that are not\n * specifically listed. In the following example, `mouseup` would have a debounce delay of 1000:\n * ```\n * ng-model-options=\"{\n * updateOn: 'default blur mouseup',\n * debounce: { 'default': 500, 'blur': 0, '*': 1000 }\n * }\"\n * ```\n * - `allowInvalid`: boolean value which indicates that the model can be set with values that did\n * not validate correctly instead of the default behavior of setting the model to undefined.\n * - `getterSetter`: boolean value which determines whether or not to treat functions bound to\n * `ngModel` as getters/setters.\n *\n *\n * **Input-type specific options**:\n *\n * - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for\n * ``, ``, ... . It understands UTC/GMT and the\n * continental US time zone abbreviations, but for general use, use a time zone offset, for\n * example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)\n * If not specified, the timezone of the browser will be used.\n * Note that changing the timezone will have no effect on the current date, and is only applied after\n * the next input / model change.\n *\n * - `timeSecondsFormat`: Defines if the `time` and `datetime-local` types should show seconds and\n * milliseconds. The option follows the format string of {@link date date filter}.\n * By default, the options is `undefined` which is equal to `'ss.sss'` (seconds and milliseconds).\n * The other options are `'ss'` (strips milliseconds), and `''` (empty string), which strips both\n * seconds and milliseconds.\n * Note that browsers that support `time` and `datetime-local` require the hour and minutes\n * part of the time string, and may show the value differently in the user interface.\n * {@link ngModelOptions#formatting-the-value-of-time-and-datetime-local- See the example}.\n *\n * - `timeStripZeroSeconds`: Defines if the `time` and `datetime-local` types should strip the\n * seconds and milliseconds from the formatted value if they are zero. This option is applied\n * after `timeSecondsFormat`.\n * This option can be used to make the formatting consistent over different browsers, as some\n * browsers with support for `time` will natively hide the milliseconds and\n * seconds if they are zero, but others won't, and browsers that don't implement these input\n * types will always show the full string.\n * {@link ngModelOptions#formatting-the-value-of-time-and-datetime-local- See the example}.\n *\n */\nvar ngModelOptionsDirective = function() {\n NgModelOptionsController.$inject = ['$attrs', '$scope'];\n function NgModelOptionsController($attrs, $scope) {\n this.$$attrs = $attrs;\n this.$$scope = $scope;\n }\n NgModelOptionsController.prototype = {\n $onInit: function() {\n var parentOptions = this.parentCtrl ? this.parentCtrl.$options : defaultModelOptions;\n var modelOptionsDefinition = this.$$scope.$eval(this.$$attrs.ngModelOptions);\n\n this.$options = parentOptions.createChild(modelOptionsDefinition);\n }\n };\n\n return {\n restrict: 'A',\n // ngModelOptions needs to run before ngModel and input directives\n priority: 10,\n require: {parentCtrl: '?^^ngModelOptions'},\n bindToController: true,\n controller: NgModelOptionsController\n };\n};\n\n\n// shallow copy over values from `src` that are not already specified on `dst`\nfunction defaults(dst, src) {\n forEach(src, function(value, key) {\n if (!isDefined(dst[key])) {\n dst[key] = value;\n }\n });\n}\n\n/**\n * @ngdoc directive\n * @name ngNonBindable\n * @restrict AC\n * @priority 1000\n * @element ANY\n *\n * @description\n * The `ngNonBindable` directive tells AngularJS not to compile or bind the contents of the current\n * DOM element, including directives on the element itself that have a lower priority than\n * `ngNonBindable`.
