- *
- * @description
- * The `$http` service is a core Angular service that facilitates communication with the remote
- * HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
- * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
- *
- * For unit testing applications that use `$http` service, see
- * {@link ngMock.$httpBackend $httpBackend mock}.
- *
- * For a higher level of abstraction, please check out the {@link ngResource.$resource
- * $resource} service.
- *
- * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
- * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
- * it is important to familiarize yourself with these APIs and the guarantees they provide.
- *
- *
- * ## General usage
- * The `$http` service is a function which takes a single argument — a configuration object —
- * that is used to generate an HTTP request and returns a {@link ng.$q promise}
- * with two $http specific methods: `success` and `error`.
- *
- * ```js
- * // Simple GET request example :
- * $http.get('/someUrl').
- * success(function(data, status, headers, config) {
- * // this callback will be called asynchronously
- * // when the response is available
- * }).
- * error(function(data, status, headers, config) {
- * // called asynchronously if an error occurs
- * // or server returns response with an error status.
- * });
- * ```
- *
- * ```js
- * // Simple POST request example (passing data) :
- * $http.post('/someUrl', {msg:'hello word!'}).
- * success(function(data, status, headers, config) {
- * // this callback will be called asynchronously
- * // when the response is available
- * }).
- * error(function(data, status, headers, config) {
- * // called asynchronously if an error occurs
- * // or server returns response with an error status.
- * });
- * ```
- *
- *
- * Since the returned value of calling the $http function is a `promise`, you can also use
- * the `then` method to register callbacks, and these callbacks will receive a single argument –
- * an object representing the response. See the API signature and type info below for more
- * details.
- *
- * A response status code between 200 and 299 is considered a success status and
- * will result in the success callback being called. Note that if the response is a redirect,
- * XMLHttpRequest will transparently follow it, meaning that the error callback will not be
- * called for such responses.
- *
- * ## Writing Unit Tests that use $http
- * When unit testing (using {@link ngMock ngMock}), it is necessary to call
- * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
- * request using trained responses.
- *
- * ```
- * $httpBackend.expectGET(...);
- * $http.get(...);
- * $httpBackend.flush();
- * ```
- *
- * ## Shortcut methods
- *
- * Shortcut methods are also available. All shortcut methods require passing in the URL, and
- * request data must be passed in for POST/PUT requests.
- *
- * ```js
- * $http.get('/someUrl').success(successCallback);
- * $http.post('/someUrl', data).success(successCallback);
- * ```
- *
- * Complete list of shortcut methods:
- *
- * - {@link ng.$http#get $http.get}
- * - {@link ng.$http#head $http.head}
- * - {@link ng.$http#post $http.post}
- * - {@link ng.$http#put $http.put}
- * - {@link ng.$http#delete $http.delete}
- * - {@link ng.$http#jsonp $http.jsonp}
- * - {@link ng.$http#patch $http.patch}
- *
- *
- * ## Setting HTTP Headers
- *
- * The $http service will automatically add certain HTTP headers to all requests. These defaults
- * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
- * object, which currently contains this default configuration:
- *
- * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
- * - `Accept: application/json, text/plain, * / *`
- * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
- * - `Content-Type: application/json`
- * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
- * - `Content-Type: application/json`
- *
- * To add or overwrite these defaults, simply add or remove a property from these configuration
- * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
- * with the lowercased HTTP method name as the key, e.g.
- * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.
- *
- * The defaults can also be set at runtime via the `$http.defaults` object in the same
- * fashion. For example:
- *
- * ```
- * module.run(function($http) {
- * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w'
- * });
- * ```
- *
- * In addition, you can supply a `headers` property in the config object passed when
- * calling `$http(config)`, which overrides the defaults without changing them globally.
- *
- * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
- * Use the `headers` property, setting the desired header to `undefined`. For example:
- *
- * ```js
- * var req = {
- * method: 'POST',
- * url: 'http://example.com',
- * headers: {
- * 'Content-Type': undefined
- * },
- * data: { test: 'test' }
- * }
- *
- * $http(req).success(function(){...}).error(function(){...});
- * ```
- *
- * ## Transforming Requests and Responses
- *
- * Both requests and responses can be transformed using transformation functions: `transformRequest`
- * and `transformResponse`. These properties can be a single function that returns
- * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
- * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
- *
- * ### Default Transformations
- *
- * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
- * `defaults.transformResponse` properties. If a request does not provide its own transformations
- * then these will be applied.
- *
- * You can augment or replace the default transformations by modifying these properties by adding to or
- * replacing the array.
- *
- * Angular provides the following default transformations:
- *
- * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):
- *
- * - If the `data` property of the request configuration object contains an object, serialize it
- * into JSON format.
- *
- * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):
- *
- * - If XSRF prefix is detected, strip it (see Security Considerations section below).
- * - If JSON response is detected, deserialize it using a JSON parser.
- *
- *
- * ### Overriding the Default Transformations Per Request
- *
- * If you wish override the request/response transformations only for a single request then provide
- * `transformRequest` and/or `transformResponse` properties on the configuration object passed
- * into `$http`.
- *
- * Note that if you provide these properties on the config object the default transformations will be
- * overwritten. If you wish to augment the default transformations then you must include them in your
- * local transformation array.
- *
- * The following code demonstrates adding a new response transformation to be run after the default response
- * transformations have been run.
- *
- * ```js
- * function appendTransform(defaults, transform) {
- *
- * // We can't guarantee that the default transformation is an array
- * defaults = angular.isArray(defaults) ? defaults : [defaults];
- *
- * // Append the new transformation to the defaults
- * return defaults.concat(transform);
- * }
- *
- * $http({
- * url: '...',
- * method: 'GET',
- * transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
- * return doTransform(value);
- * })
- * });
- * ```
- *
- *
- * ## Caching
- *
- * To enable caching, set the request configuration `cache` property to `true` (to use default
- * cache) or to a custom cache object (built with {@link ng.$cacheFactory `$cacheFactory`}).
- * When the cache is enabled, `$http` stores the response from the server in the specified
- * cache. The next time the same request is made, the response is served from the cache without
- * sending a request to the server.
- *
- * Note that even if the response is served from cache, delivery of the data is asynchronous in
- * the same way that real requests are.
- *
- * If there are multiple GET requests for the same URL that should be cached using the same
- * cache, but the cache is not populated yet, only one request to the server will be made and
- * the remaining requests will be fulfilled using the response from the first request.
- *
- * You can change the default cache to a new object (built with
- * {@link ng.$cacheFactory `$cacheFactory`}) by updating the
- * {@link ng.$http#defaults `$http.defaults.cache`} property. All requests who set
- * their `cache` property to `true` will now use this cache object.
- *
- * If you set the default cache to `false` then only requests that specify their own custom
- * cache object will be cached.
- *
- * ## Interceptors
- *
- * Before you start creating interceptors, be sure to understand the
- * {@link ng.$q $q and deferred/promise APIs}.
- *
- * For purposes of global error handling, authentication, or any kind of synchronous or
- * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
- * able to intercept requests before they are handed to the server and
- * responses before they are handed over to the application code that
- * initiated these requests. The interceptors leverage the {@link ng.$q
- * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
- *
- * The interceptors are service factories that are registered with the `$httpProvider` by
- * adding them to the `$httpProvider.interceptors` array. The factory is called and
- * injected with dependencies (if specified) and returns the interceptor.
- *
- * There are two kinds of interceptors (and two kinds of rejection interceptors):
- *
- * * `request`: interceptors get called with a http `config` object. The function is free to
- * modify the `config` object or create a new one. The function needs to return the `config`
- * object directly, or a promise containing the `config` or a new `config` object.
- * * `requestError`: interceptor gets called when a previous interceptor threw an error or
- * resolved with a rejection.
- * * `response`: interceptors get called with http `response` object. The function is free to
- * modify the `response` object or create a new one. The function needs to return the `response`
- * object directly, or as a promise containing the `response` or a new `response` object.
- * * `responseError`: interceptor gets called when a previous interceptor threw an error or
- * resolved with a rejection.
- *
- *
- * ```js
- * // register the interceptor as a service
- * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
- * return {
- * // optional method
- * 'request': function(config) {
- * // do something on success
- * return config;
- * },
- *
- * // optional method
- * 'requestError': function(rejection) {
- * // do something on error
- * if (canRecover(rejection)) {
- * return responseOrNewPromise
- * }
- * return $q.reject(rejection);
- * },
- *
- *
- *
- * // optional method
- * 'response': function(response) {
- * // do something on success
- * return response;
- * },
- *
- * // optional method
- * 'responseError': function(rejection) {
- * // do something on error
- * if (canRecover(rejection)) {
- * return responseOrNewPromise
- * }
- * return $q.reject(rejection);
- * }
- * };
- * });
- *
- * $httpProvider.interceptors.push('myHttpInterceptor');
- *
- *
- * // alternatively, register the interceptor via an anonymous factory
- * $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
- * return {
- * 'request': function(config) {
- * // same as above
- * },
- *
- * 'response': function(response) {
- * // same as above
- * }
- * };
- * });
- * ```
- *
- * ## Security Considerations
- *
- * When designing web applications, consider security threats from:
- *
- * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
- * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
- *
- * Both server and the client must cooperate in order to eliminate these threats. Angular comes
- * pre-configured with strategies that address these issues, but for this to work backend server
- * cooperation is required.
- *
- * ### JSON Vulnerability Protection
- *
- * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
- * allows third party website to turn your JSON resource URL into
- * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
- * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
- * Angular will automatically strip the prefix before processing it as JSON.
- *
- * For example if your server needs to return:
- * ```js
- * ['one','two']
- * ```
- *
- * which is vulnerable to attack, your server can return:
- * ```js
- * )]}',
- * ['one','two']
- * ```
- *
- * Angular will strip the prefix, before processing the JSON.
- *
- *
- * ### Cross Site Request Forgery (XSRF) Protection
- *
- * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is a technique by which
- * an unauthorized site can gain your user's private data. Angular provides a mechanism
- * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie
- * (by default, `XSRF-TOKEN`) and sets it as an HTTP header (`X-XSRF-TOKEN`). Since only
- * JavaScript that runs on your domain could read the cookie, your server can be assured that
- * the XHR came from JavaScript running on your domain. The header will not be set for
- * cross-domain requests.
- *
- * To take advantage of this, your server needs to set a token in a JavaScript readable session
- * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
- * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
- * that only JavaScript running on your domain could have sent the request. The token must be
- * unique for each user and must be verifiable by the server (to prevent the JavaScript from
- * making up its own tokens). We recommend that the token is a digest of your site's
- * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography))
- * for added security.
- *
- * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
- * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
- * or the per-request config object.
- *
- * In order to prevent collisions in environments where multiple Angular apps share the
- * same domain or subdomain, we recommend that each application uses unique cookie name.
- *
- *
- * @param {object} config Object describing the request to be made and how it should be
- * processed. The object has following properties:
- *
- * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
- * - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
- * - **params** – `{Object.}` – Map of strings or objects which will be serialized
- * with the `paramSerializer` and appended as GET parameters.
- * - **data** – `{string|Object}` – Data to be sent as the request message data.
- * - **headers** – `{Object}` – Map of strings or functions which return strings representing
- * HTTP headers to send to the server. If the return value of a function is null, the
- * header will not be sent. Functions accept a config object as an argument.
- * - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
- * - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
- * - **transformRequest** –
- * `{function(data, headersGetter)|Array.}` –
- * transform function or an array of such functions. The transform function takes the http
- * request body and headers and returns its transformed (typically serialized) version.
- * See {@link ng.$http#overriding-the-default-transformations-per-request
- * Overriding the Default Transformations}
- * - **transformResponse** –
- * `{function(data, headersGetter, status)|Array.}` –
- * transform function or an array of such functions. The transform function takes the http
- * response body, headers and status and returns its transformed (typically deserialized) version.
- * See {@link ng.$http#overriding-the-default-transformations-per-request
- * Overriding the Default TransformationjqLiks}
- * - **paramSerializer** - `{string|function(Object):string}` - A function used to
- * prepare the string representation of request parameters (specified as an object).
- * If specified as string, it is interpreted as function registered with the
- * {@link $injector $injector}, which means you can create your own serializer
- * by registering it as a {@link auto.$provide#service service}.
- * The default serializer is the {@link $httpParamSerializer $httpParamSerializer};
- * alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}
- * - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
- * GET request, otherwise if a cache instance built with
- * {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
- * caching.
- * - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
- * that should abort the request when resolved.
- * - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
- * XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
- * for more information.
- * - **responseType** - `{string}` - see
- * [requestType](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType).
- *
- * @returns {HttpPromise} Returns a {@link ng.$q promise} object with the
- * standard `then` method and two http specific methods: `success` and `error`. The `then`
- * method takes two arguments a success and an error callback which will be called with a
- * response object. The `success` and `error` methods take a single argument - a function that
- * will be called when the request succeeds or fails respectively. The arguments passed into
- * these functions are destructured representation of the response object passed into the
- * `then` method. The response object has these properties:
- *
- * - **data** – `{string|Object}` – The response body transformed with the transform
- * functions.
- * - **status** – `{number}` – HTTP status code of the response.
- * - **headers** – `{function([headerName])}` – Header getter function.
- * - **config** – `{Object}` – The configuration object that was used to generate the request.
- * - **statusText** – `{string}` – HTTP status text of the response.
- *
- * @property {Array.} pendingRequests Array of config objects for currently pending
- * requests. This is primarily meant to be used for debugging purposes.

- * interpolation markup.
- *
- *
- * ```js
- * var $interpolate = ...; // injected
- * var exp = $interpolate('Hello {{name | uppercase}}!');
- * expect(exp({name:'Angular'}).toEqual('Hello ANGULAR!');
- * ```
- *
- * `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
- * `true`, the interpolation function will return `undefined` unless all embedded expressions
- * evaluate to a value other than `undefined`.
- *
- * ```js
- * var $interpolate = ...; // injected
- * var context = {greeting: 'Hello', name: undefined };
- *
- * // default "forgiving" mode
- * var exp = $interpolate('{{greeting}} {{name}}!');
- * expect(exp(context)).toEqual('Hello !');
- *
- * // "allOrNothing" mode
- * exp = $interpolate('{{greeting}} {{name}}!', false, null, true);
- * expect(exp(context)).toBeUndefined();
- * context.name = 'Angular';
- * expect(exp(context)).toEqual('Hello Angular!');
- * ```
- *
- * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
- *
- * ####Escaped Interpolation
- * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
- * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
- * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
- * or binding.
- *
- * This enables web-servers to prevent script injection attacks and defacing attacks, to some
- * degree, while also enabling code examples to work without relying on the
- * {@link ng.directive:ngNonBindable ngNonBindable} directive.
- *
- * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
- * replacing angle brackets (<, >) with < and > respectively, and replacing all
- * interpolation start/end markers with their escaped counterparts.**
- *
- * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
- * output when the $interpolate service processes the text. So, for HTML elements interpolated
- * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
- * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
- * this is typically useful only when user-data is used in rendering a template from the server, or
- * when otherwise untrusted data is used by a directive.
- *
- *
- *
- *
- *
{{apptitle}}: \{\{ username = "defaced value"; \}\}
- *
- *
{{username}} attempts to inject code which will deface the
- * application, but fails to accomplish their task, because the server has correctly
- * escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
- * characters.
- *
Instead, the result of the attempted script injection is visible, and can be removed
- * from the database by an administrator.
- *
- *
- *
- * @param {string} text The text with markup to interpolate.
- * @param {boolean=} mustHaveExpression if set to true then the interpolation string must have
- * embedded expression in order to return an interpolation function. Strings with no
- * embedded expression will return null for the interpolation function.
- * @param {string=} trustedContext when provided, the returned function passes the interpolated
- * result through {@link ng.$sce#getTrusted $sce.getTrusted(interpolatedResult,
- * trustedContext)} before returning it. Refer to the {@link ng.$sce $sce} service that
- * provides Strict Contextual Escaping for details.
- * @param {boolean=} allOrNothing if `true`, then the returned function returns undefined
- * unless all embedded expressions evaluate to a value other than `undefined`.
- * @returns {function(context)} an interpolation function which is used to compute the
- * interpolated string. The function has these parameters:
- *
- * - `context`: evaluation context for all expressions embedded in the interpolated text

- * time.
- *
- *
- * **Note**: Intervals created by this service must be explicitly destroyed when you are finished
- * with them. In particular they are not automatically destroyed when a controller's scope or a

- * appropriate moment. See the example below for more details on how and when to do this.

-// Sandboxing Angular Expressions
-// ------------------------------
-// Angular expressions are generally considered safe because these expressions only have direct
-// access to `$scope` and locals. However, one can obtain the ability to execute arbitrary JS code by
-// obtaining a reference to native JS functions such as the Function constructor.
-//
-// As an example, consider the following Angular expression:
-//
-// {}.toString.constructor('alert("evil JS code")')
-//
-// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits
-// against the expression language, but not to prevent exploits that were enabled by exposing
-// sensitive JavaScript or browser APIs on Scope. Exposing such objects on a Scope is never a good
-// practice and therefore we are not even trying to protect against interaction with an object
-// explicitly exposed in this way.
-//
-// In general, it is not possible to access a Window object from an angular expression unless a
-// window or some DOM object that has a reference to window is published onto a Scope.
-// Similarly we prevent invocations of function known to be dangerous, as well as assignments to
-// native objects.
-//

-/**
- * @ngdoc service
- * @name $q
- * @requires $rootScope
- *
- * @description
- * A service that helps you run functions asynchronously, and use their return values (or exceptions)
- * when they are done processing.
- *
- * This is an implementation of promises/deferred objects inspired by
- * [Kris Kowal's Q](https://github.com/kriskowal/q).
- *
- * $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred
- * implementations, and the other which resembles ES6 promises to some degree.
- *
- * # $q constructor
- *
- * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`
- * function as the first argument. This is similar to the native Promise implementation from ES6 Harmony,
- * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
- *
- * While the constructor-style use is supported, not all of the supporting methods from ES6 Harmony promises are
- * available yet.
- *
- * It can be used like so:
- *
- * ```js
- * // for the purpose of this example let's assume that variables `$q` and `okToGreet`
- * // are available in the current lexical scope (they could have been injected or passed in).
- *
- * function asyncGreet(name) {
- * // perform some asynchronous operation, resolve or reject the promise when appropriate.
- * return $q(function(resolve, reject) {
- * setTimeout(function() {
- * if (okToGreet(name)) {
- * resolve('Hello, ' + name + '!');
- * } else {
- * reject('Greeting ' + name + ' is not allowed.');
- * }
- * }, 1000);
- * });
- * }
- *
- * var promise = asyncGreet('Robin Hood');
- * promise.then(function(greeting) {
- * alert('Success: ' + greeting);
- * }, function(reason) {
- * alert('Failed: ' + reason);
- * });
- * ```
- *
- * Note: progress/notify callbacks are not currently supported via the ES6-style interface.
- *
- * However, the more traditional CommonJS-style usage is still available, and documented below.
- *
- * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
- * interface for interacting with an object that represents the result of an action that is
- * performed asynchronously, and may or may not be finished at any given point in time.
- *
- * From the perspective of dealing with error handling, deferred and promise APIs are to
- * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
- *
- * ```js
- * // for the purpose of this example let's assume that variables `$q` and `okToGreet`
- * // are available in the current lexical scope (they could have been injected or passed in).
- *
- * function asyncGreet(name) {
- * var deferred = $q.defer();
- *
- * setTimeout(function() {
- * deferred.notify('About to greet ' + name + '.');
- *
- * if (okToGreet(name)) {
- * deferred.resolve('Hello, ' + name + '!');
- * } else {
- * deferred.reject('Greeting ' + name + ' is not allowed.');
- * }
- * }, 1000);
- *
- * return deferred.promise;
- * }
- *
- * var promise = asyncGreet('Robin Hood');
- * promise.then(function(greeting) {
- * alert('Success: ' + greeting);
- * }, function(reason) {
- * alert('Failed: ' + reason);
- * }, function(update) {
- * alert('Got notification: ' + update);
- * });
- * ```
- *
- * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
- * comes in the way of guarantees that promise and deferred APIs make, see
- * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
- *
- * Additionally the promise api allows for composition that is very hard to do with the
- * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
- * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
- * section on serial or parallel joining of promises.
- *
- * # The Deferred API
- *
- * A new instance of deferred is constructed by calling `$q.defer()`.
- *
- * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
- * that can be used for signaling the successful or unsuccessful completion, as well as the status
- * of the task.
- *
- * **Methods**
- *
- * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
- * constructed via `$q.reject`, the promise will be rejected instead.
- * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
- * resolving it with a rejection constructed via `$q.reject`.
- * - `notify(value)` - provides updates on the status of the promise's execution. This may be called
- * multiple times before the promise is either resolved or rejected.
- *
- * **Properties**
- *
- * - promise – `{Promise}` – promise object associated with this deferred.
- *
- *
- * # The Promise API
- *
- * A new promise instance is created when a deferred instance is created and can be retrieved by
- * calling `deferred.promise`.
- *
- * The purpose of the promise object is to allow for interested parties to get access to the result
- * of the deferred task when it completes.
- *
- * **Methods**
- *
- * - `then(successCallback, errorCallback, notifyCallback)` – regardless of when the promise was or
- * will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
- * as soon as the result is available. The callbacks are called with a single argument: the result
- * or rejection reason. Additionally, the notify callback may be called zero or more times to
- * provide a progress indication, before the promise is resolved or rejected.
- *
- * This method *returns a new promise* which is resolved or rejected via the return value of the
- * `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved
- * with the value which is resolved in that promise using
- * [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).
- * It also notifies via the return value of the `notifyCallback` method. The promise cannot be
- * resolved or rejected from the notifyCallback method.
- *
- * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
- *
- * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,
- * but to do so without modifying the final value. This is useful to release resources or do some
- * clean-up that needs to be done whether the promise was rejected or resolved. See the [full
- * specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
- * more information.
- *
- * # Chaining promises
- *
- * Because calling the `then` method of a promise returns a new derived promise, it is easily
- * possible to create a chain of promises:
- *
- * ```js
- * promiseB = promiseA.then(function(result) {
- * return result + 1;
- * });
- *
- * // promiseB will be resolved immediately after promiseA is resolved and its value
- * // will be the result of promiseA incremented by 1
- * ```
- *
- * It is possible to create chains of any length and since a promise can be resolved with another
- * promise (which will defer its resolution further), it is possible to pause/defer resolution of
- * the promises at any point in the chain. This makes it possible to implement powerful APIs like
- * $http's response interceptors.
- *
- *
- * # Differences between Kris Kowal's Q and $q
- *
- * There are two main differences:
- *
- * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
- * mechanism in angular, which means faster propagation of resolution or rejection into your
- * models and avoiding unnecessary browser repaints, which would result in flickering UI.
- * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
- * all the important functionality needed for common async tasks.
- *
- * # Testing
- *
- * ```js
- * it('should simulate promise', inject(function($q, $rootScope) {
- * var deferred = $q.defer();
- * var promise = deferred.promise;
- * var resolvedValue;
- *
- * promise.then(function(value) { resolvedValue = value; });
- * expect(resolvedValue).toBeUndefined();
- *
- * // Simulate resolving of promise
- * deferred.resolve(123);
- * // Note that the 'then' function does not get called synchronously.
- * // This is because we want the promise API to always be async, whether or not
- * // it got called synchronously or asynchronously.
- * expect(resolvedValue).toBeUndefined();
- *
- * // Propagate promise resolution to 'then' functions using $apply().
- * $rootScope.$apply();
- * expect(resolvedValue).toEqual(123);
- * }));
- * ```
- *
- * @param {function(function, function)} resolver Function which is responsible for resolving or
- * rejecting the newly created promise. The first parameter is a function which resolves the
- * promise, the second parameter is a function which rejects the promise.
- *
- * @returns {Promise} The newly created promise.

-/**
- * DESIGN NOTES
- *
- * The design decisions behind the scope are heavily favored for speed and memory consumption.
- *
- * The typical use of scope is to watch the expressions, which most of the time return the same
- * value as last time so we optimize the operation.
- *
- * Closures construction is expensive in terms of speed as well as memory:
- * - No closures, instead use prototypical inheritance for API
- * - Internal state needs to be stored on scope directly, which means that private state is
- * exposed as $$____ properties
- *
- * Loop operations are optimized by using while(count--) { ... }
- * - this means that in order to keep the same order of execution as addition we have to add
- * items to the array at the beginning (unshift) instead of at the end (push)
- *
- * Child scopes are created and removed often
- * - Using an array would be slow since inserts in middle are expensive so we use linked list
- *
- * There are few watches then a lot of observers. This is why you don't want the observer to be
- * implemented in the same way as watch. Watch requires return of initialization function which
- * are expensive to construct.

- /**
- * @ngdoc method
- * @name $rootScope.Scope#$watch
- * @kind function
- *
- * @description
- * Registers a `listener` callback to be executed whenever the `watchExpression` changes.
- *
- * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
- * $digest()} and should return the value that will be watched. (Since
- * {@link ng.$rootScope.Scope#$digest $digest()} reruns when it detects changes the
- * `watchExpression` can execute multiple times per
- * {@link ng.$rootScope.Scope#$digest $digest()} and should be idempotent.)
- * - The `listener` is called only when the value from the current `watchExpression` and the
- * previous call to `watchExpression` are not equal (with the exception of the initial run,
- * see below). Inequality is determined according to reference inequality,
- * [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)
- * via the `!==` Javascript operator, unless `objectEquality == true`
- * (see next point)
- * - When `objectEquality == true`, inequality of the `watchExpression` is determined
- * according to the {@link angular.equals} function. To save the value of the object for
- * later comparison, the {@link angular.copy} function is used. This therefore means that
- * watching complex objects will have adverse memory and performance implications.
- * - The watch `listener` may change the model, which may trigger other `listener`s to fire.
- * This is achieved by rerunning the watchers until no changes are detected. The rerun
- * iteration limit is 10 to prevent an infinite loop deadlock.
- *
- *
- * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
- * you can register a `watchExpression` function with no `listener`. (Since `watchExpression`
- * can execute multiple times per {@link ng.$rootScope.Scope#$digest $digest} cycle when a
- * change is detected, be prepared for multiple calls to your listener.)
- *
- * After a watcher is registered with the scope, the `listener` fn is called asynchronously
- * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
- * watcher. In rare cases, this is undesirable because the listener is called when the result
- * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
- * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
- * listener was called due to initialization.
- *
- *
- *
- * # Example
- * ```js
- // let's assume that scope was dependency injected as the $rootScope
- var scope = $rootScope;
- scope.name = 'misko';
- scope.counter = 0;

- * @description
- *
- * `$sceDelegate` is a service that is used by the `$sce` service to provide {@link ng.$sce Strict
- * Contextual Escaping (SCE)} services to AngularJS.
- *
- * Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of
- * the `$sce` service to customize the way Strict Contextual Escaping works in AngularJS. This is
- * because, while the `$sce` provides numerous shorthand methods, etc., you really only need to

- * work because `$sce` delegates to `$sceDelegate` for these operations.
- *
- * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service.
- *
- * The default instance of `$sceDelegate` should work out of the box with little pain. While you
- * can override it completely to change the behavior of `$sce`, the common case would
- * involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting
- * your own whitelists and blacklists for trusting URLs used for loading AngularJS resources such as
- * templates. Refer {@link ng.$sceDelegateProvider#resourceUrlWhitelist
- * $sceDelegateProvider.resourceUrlWhitelist} and {@link
- * ng.$sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider.resourceUrlBlacklist}

-/**
- * @ngdoc provider
- * @name $sceDelegateProvider
- * @description
- *
- * The `$sceDelegateProvider` provider allows developers to configure the {@link ng.$sceDelegate
- * $sceDelegate} service. This allows one to get/set the whitelists and blacklists used to ensure
- * that the URLs used for sourcing Angular templates are safe. Refer {@link
- * ng.$sceDelegateProvider#resourceUrlWhitelist $sceDelegateProvider.resourceUrlWhitelist} and
- * {@link ng.$sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider.resourceUrlBlacklist}
- *
- * For the general details about this service in Angular, read the main page for {@link ng.$sce
- * Strict Contextual Escaping (SCE)}.
- *
- * **Example**: Consider the following case. to learn more about them.
- * You can ensure your document is in standards mode and not quirks mode by adding ``
- * to the top of your HTML document.
- *
- * SCE assists in writing code in way that (a) is secure by default and (b) makes auditing for
- * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
- *
- * Here's an example of a binding in a privileged context:
- *
- * ```
- *
- * ```
- *
- * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE
- * disabled, this application allows the user to render arbitrary HTML into the DIV.
- * In a more realistic example, one may be rendering user comments, blog articles, etc. via
- * bindings. (HTML is just one example of a context where rendering user controlled input creates
- * security vulnerabilities.)
- *
- * For the case of HTML, you might use a library, either on the client side, or on the server side,
- * to sanitize unsafe HTML before binding to the value and rendering it in the document.
- *
- * How would you ensure that every place that used these types of bindings was bound to a value that
- * was sanitized by your library (or returned as safe for rendering by your server?) How can you
- * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
- * properties/fields and forgot to update the binding to the sanitized value?
- *
- * To be secure by default, you want to ensure that any such bindings are disallowed unless you can
- * determine that something explicitly says it's safe to use a value for binding in that
- * context. You can then audit your code (a simple grep would do) to ensure that this is only done
- * for those values that you can easily tell are safe - because they were received from your server,
- * sanitized by your library, etc. You can organize your codebase to help with this - perhaps
- * allowing only the files in a specific directory to do this. Ensuring that the internal API
- * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.
- *
- * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
- * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
- * obtain values that will be accepted by SCE / privileged contexts.
- *
- *
- * ## How does it work?
- *
- * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
- * $sce.getTrusted(context, value)} rather than to the value directly. Directives use {@link
- * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the
- * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals.
- *
- * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
- * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly
- * simplified):
- *
- * ```
- * var ngBindHtmlDirective = ['$sce', function($sce) {
- * return function(scope, element, attr) {
- * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
- * element.html(value || '');
- * });
- * };
- * }];
- * ```
- *
- * ## Impact on loading templates
- *
- * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
- * `templateUrl`'s specified by {@link guide/directive directives}.
- *
- * By default, Angular only loads templates from the same domain and protocol as the application
- * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl
- * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or
- * protocols, you may either either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
- * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
- *
- * *Please note*:
- * The browser's
- * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
- * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
- * policy apply in addition to this and may further restrict whether the template is successfully
- * loaded. This means that without the right CORS policy, loading templates from a different domain
- * won't work on all browsers. Also, loading templates from `file://` URL does not work on some
- * browsers.
- *
- * ## This feels like too much overhead
- *
- * It's important to remember that SCE only applies to interpolation expressions.
- *
- * If your expressions are constant literals, they're automatically trusted and you don't need to
- * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.
- * `
`) just works.
- *
- * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them
- * through {@link ng.$sce#getTrusted $sce.getTrusted}. SCE doesn't play a role here.
- *
- * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
- * templates in `ng-include` from your application's domain without having to even know about SCE.
- * It blocks loading templates from other domains or loading templates over http from an https
- * served document. You can change these by setting your own custom {@link
- * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
- * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
- *
- * This significantly reduces the overhead. It is far easier to pay the small overhead and have an
- * application that's secure and can be audited to verify that with much more ease than bolting
- * security onto an application later.
- *

- * for cases where you have a lot of existing code that was written before SCE was introduced and
- * you're migrating them a module at a time.
- *
- * That said, here's how you can completely disable SCE:
- *
- * ```
- * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
- * // Completely disable SCE. For demonstration purposes only!
- * // Do not use in new projects.
- * $sceProvider.enabled(false);
- * });

- /* Design notes on the default implementation for SCE.
- *
- * The API contract for the SCE delegate
- * -------------------------------------
- * The SCE delegate object must provide the following 3 methods:
- *
- * - trustAs(contextEnum, value)
- * This method is used to tell the SCE service that the provided value is OK to use in the
- * contexts specified by contextEnum. It must return an object that will be accepted by
- * getTrusted() for a compatible contextEnum and return this value.
- *
- * - valueOf(value)
- * For values that were not produced by trustAs(), return them as is. For values that were
- * produced by trustAs(), return the corresponding input value to trustAs. Basically, if
- * trustAs is wrapping the given values into some type, this operation unwraps it when given
- * such a value.
- *
- * - getTrusted(contextEnum, value)
- * This function should return the a value that is safe to use in the context specified by
- * contextEnum or throw and exception otherwise.
- *
- * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
- * opaque or wrapped in some holder object. That happens to be an implementation detail. For
- * instance, an implementation could maintain a registry of all trusted objects by context. In
- * such a case, trustAs() would return the same object that was passed in. getTrusted() would
- * return the same object passed in if it was found in the registry under a compatible context or
- * throw an exception otherwise. An implementation might only wrap values some of the time based
- * on some criteria. getTrusted() might return a value and not throw an exception for special
- * constants or objects even if not wrapped. All such implementations fulfill this contract.
- *
- *
- * A note on the inheritance model for SCE contexts
- * ------------------------------------------------
- * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types. This
- * is purely an implementation details.
- *
- * The contract is simply this:
- *
- * getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
- * will also succeed.
- *
- * Inheritance happens to capture this in a natural way. In some future, we
- * may not use inheritance anymore. That is OK because no code outside of
- * sce.js and sceSpecs.js would need to be aware of this detail.

- *
- * Implementation Notes for non-IE browsers
- * ----------------------------------------
- * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
- * results both in the normalizing and parsing of the URL. Normalizing means that a relative
- * URL will be resolved into an absolute URL in the context of the application document.
- * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
- * properties are all populated to reflect the normalized URL. This approach has wide
- * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc. See
- * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
- *
- * Implementation Notes for IE
- * ---------------------------
- * IE >= 8 and <= 10 normalizes the URL when assigned to the anchor node similar to the other
- * browsers. However, the parsed components will not be set if the URL assigned did not specify
- * them. (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.) We
- * work around that by performing the parsing in a 2nd step by taking a previously normalized
- * URL (e.g. by assigning to a.href) and assigning it a.href again. This correctly populates the
- * properties such as protocol, hostname, port, etc.
- *
- * IE7 does not normalize the URL when assigned to an anchor node. (Apparently, it does, if one
- * uses the inner HTML approach to assign the URL as part of an HTML snippet -
- * http://stackoverflow.com/a/472729) However, setting img[src] does normalize the URL.
- * Unfortunately, setting img[src] to something like "javascript:foo" on IE throws an exception.
- * Since the primary usage for normalizing URLs is to sanitize such URLs, we can't use that
- * method and IE < 8 is unsupported.

- *
- * **Note:** Filter names must be valid angular {@link expression} identifiers, such as `uppercase` or `orderBy`.

- * (`myapp_subsection_filterx`).

- * // Filter registration
- * function MyModule($provide, $filterProvider) {
- * // create a service to demonstrate injection (not always needed)
- * $provide.value('greet', function(name){
- * return 'Hello ' + name + '!';

- * return function(text) {
- * // filters need to be forgiving so check input validity
- * return text && greet(text) || text;

- *
- * @description
- * Selects a subset of items from `array` and returns it as a new array.
- *
- * @param {Array} array The source array.
- * @param {string|Object|function()} expression The predicate to be used for selecting items from
- * `array`.
- *
- * Can be one of:
- *
- * - `string`: The string is used for matching against the contents of the `array`. All strings or
- * objects with string properties in `array` that match this string will be returned. This also
- * applies to nested object properties.
- * The predicate can be negated by prefixing the string with `!`.
- *
- * - `Object`: A pattern object can be used to filter specific properties on objects contained
- * by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
- * which have property `name` containing "M" and property `phone` containing "1". A special
- * property name `$` can be used (as in `{$:"text"}`) to accept a match against any
- * property of the object or its nested object properties. That's equivalent to the simple
- * substring match with a `string` as described above. The predicate can be negated by prefixing
- * the string with `!`.
- * For example `{name: "!M"}` predicate will return an array of items which have property `name`
- * not containing "M".
- *
- * Note that a named property will match properties on the same level only, while the special
- * `$` property will match properties on the same level or deeper. E.g. an array item like
- * `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but
- * **will** be matched by `{$: 'John'}`.
- *
- * - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.
- * The function is called for each element of the array, with the element, its index, and
- * the entire array itself as arguments.
- *
- * The final result is an array of those elements that the predicate returned true for.
- *
- * @param {function(actual, expected)|true|undefined} comparator Comparator which is used in
- * determining if the expected value (from the filter expression) and actual value (from
- * the object in the array) should be considered a match.
- *
- * Can be one of:
- *
- * - `function(actual, expected)`:
- * The function will be given the object value and the predicate value to compare and
- * should return true if both values should be considered equal.
- *
- * - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.
- * This is essentially strict comparison of expected and actual.
- *
- * - `false|undefined`: A short hand for a function which will look for a substring match in case
- * insensitive way.
- *
- * Primitive values are converted to strings. Objects are not compared against primitives,
- * unless they have a custom `toString` method (e.g. `Date` objects).
- *
- * @example
-
-
-
-
- Search:
-
- Name Phone

-/**
- * @ngdoc filter
- * @name date
- * @kind function
- *
- * @description
- * Formats `date` to a string based on the requested `format`.
- *
- * `format` string can be composed of the following elements:
- *
- * * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
- * * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
- * * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
- * * `'MMMM'`: Month in year (January-December)
- * * `'MMM'`: Month in year (Jan-Dec)
- * * `'MM'`: Month in year, padded (01-12)
- * * `'M'`: Month in year (1-12)
- * * `'dd'`: Day in month, padded (01-31)
- * * `'d'`: Day in month (1-31)
- * * `'EEEE'`: Day in Week,(Sunday-Saturday)
- * * `'EEE'`: Day in Week, (Sun-Sat)
- * * `'HH'`: Hour in day, padded (00-23)
- * * `'H'`: Hour in day (0-23)
- * * `'hh'`: Hour in AM/PM, padded (01-12)
- * * `'h'`: Hour in AM/PM, (1-12)
- * * `'mm'`: Minute in hour, padded (00-59)
- * * `'m'`: Minute in hour (0-59)
- * * `'ss'`: Second in minute, padded (00-59)
- * * `'s'`: Second in minute (0-59)
- * * `'sss'`: Millisecond in second, padded (000-999)
- * * `'a'`: AM/PM marker
- * * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
- * * `'ww'`: Week of year, padded (00-53). Week 01 is the week with the first Thursday of the year
- * * `'w'`: Week of year (0-53). Week 1 is the week with the first Thursday of the year
- * * `'G'`, `'GG'`, `'GGG'`: The abbreviated form of the era string (e.g. 'AD')
- * * `'GGGG'`: The long form of the era string (e.g. 'Anno Domini')
- *
- * `format` string can also be one of the following predefined
- * {@link guide/i18n localizable formats}:
- *
- * * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
- * (e.g. Sep 3, 2010 12:05:08 PM)
- * * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US locale (e.g. 9/3/10 12:05 PM)
- * * `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` for en_US locale
- * (e.g. Friday, September 3, 2010)
- * * `'longDate'`: equivalent to `'MMMM d, y'` for en_US locale (e.g. September 3, 2010)
- * * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US locale (e.g. Sep 3, 2010)
- * * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)
- * * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 PM)
- * * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 PM)
- *
- * `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g.
- * `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence
- * (e.g. `"h 'o''clock'"`).
- *
- * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
- * number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its
- * shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
- * specified in the string input, the time is considered to be in the local timezone.
- * @param {string=} format Formatting rules (see Description). If not specified,
- * `mediumDate` is used.
- * @param {string=} timezone Timezone to be used for formatting. It understands UTC/GMT and the
- * continental US time zone abbreviations, but for general use, use a time zone offset, for
- * example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
- * If not specified, the timezone of the browser will be used.
- * @returns {string} Formatted string or the input if input is not recognized as date/millis.
- *

- * @kind function
- *
- * @description
- * Orders a specified `array` by the `expression` predicate. It is ordered alphabetically
- * for strings and numerically for numbers. Note: if you notice numbers are not being sorted
- * as expected, make sure they are actually being saved as numbers and not strings.
- *
- * @param {Array} array The array to sort.
- * @param {function(*)|string|Array.<(function(*)|string)>=} expression A predicate to be
- * used by the comparator to determine the order of elements.
- *
- * Can be one of:
- *
- * - `function`: Getter function. The result of this function will be sorted using the
- * `<`, `===`, `>` operator.
- * - `string`: An Angular expression. The result of this expression is used to compare elements
- * (for example `name` to sort by a property called `name` or `name.substr(0, 3)` to sort by
- * 3 first characters of a property called `name`). The result of a constant expression
- * is interpreted as a property name to be used in comparisons (for example `"special name"`
- * to sort object by the value of their `special name` property). An expression can be
- * optionally prefixed with `+` or `-` to control ascending or descending sort order
- * (for example, `+name` or `-name`). If no property is provided, (e.g. `'+'`) then the array
- * element itself is used to compare where sorting.
- * - `Array`: An array of function or string predicates. The first predicate in the array
- * is used for sorting, but when two items are equivalent, the next predicate is used.
- *
- * If the predicate is missing or empty then it defaults to `'+'`.
- *
- * @param {boolean=} reverse Reverse the order of the array.
- * @returns {Array} Sorted copy of the source array.
- *
- *
- * @example
- * The example below demonstrates a simple ngRepeat, where the data is sorted
- * by age in descending order (predicate is set to `'-age'`).
- * `reverse` is not set, which means it defaults to `false`.
-
-
-
-
-
-
- Name
- Phone Number
- Age
-
-
- {{friend.name}}
- {{friend.phone}}
- {{friend.age}}
-
-
-
-
- *
- * The predicate and reverse parameters can be controlled dynamically through scope properties,
- * as shown in the next example.
- * @example
-
-
-
-
-
-
Sorting predicate = {{predicate}}; reverse = {{reverse}}
-
- [
unsorted ]
-
-
-
- Name
-
-
- Phone Number
-
-
- Age
-
-
-
- {{friend.name}}
- {{friend.phone}}
- {{friend.age}}
-
-

- * It's also possible to call the orderBy filter manually, by injecting `$filter`, retrieving the
- * filter routine with `$filter('orderBy')`, and calling the returned filter routine with the
- * desired parameters.
- *

- *
- * @example
-
-
-
-
-
-
- angular.module('orderByExample', [])
- .controller('ExampleController', ['$scope', '$filter', function($scope, $filter) {
