/**
 * @ngdoc service
 * @name $resource
 * @requires $http
 * @requires ng.$log
 * @requires $q
 * @requires ng.$timeout
 *
 * @description
 * A factory which creates a resource object that lets you interact with
 * [RESTful](http://en.wikipedia.org/wiki/Representational_State_Transfer) server-side data sources.
 *
 * The returned resource object has action methods which provide high-level behaviors without
 * the need to interact with the low level {@link ng.$http $http} service.
 *
 * Requires the {@link ngResource `ngResource`} module to be installed.
 *
 * By default, trailing slashes will be stripped from the calculated URLs,
 * which can pose problems with server backends that do not expect that
 * behavior.  This can be disabled by configuring the `$resourceProvider` like
 * this:
 *
 * ```js
     app.config(['$resourceProvider', function($resourceProvider) {
       // Don't strip trailing slashes from calculated URLs
       $resourceProvider.defaults.stripTrailingSlashes = false;
     }]);
 * ```
 *
 * @param {string} url A parameterized URL template with parameters prefixed by `:` as in
 *   `/user/:username`. If you are using a URL with a port number (e.g.
 *   `http://example.com:8080/api`), it will be respected.
 *
 *   If you are using a url with a suffix, just add the suffix, like this:
 *   `$resource('http://example.com/resource.json')` or `$resource('http://example.com/:id.json')`
 *   or even `$resource('http://example.com/resource/:resource_id.:format')`
 *   If the parameter before the suffix is empty, :resource_id in this case, then the `/.` will be
 *   collapsed down to a single `.`.  If you need this sequence to appear and not collapse then you
 *   can escape it with `/\.`.
 *
 * @param {Object=} paramDefaults Default values for `url` parameters. These can be overridden in
 *   `actions` methods. If a parameter value is a function, it will be called every time
 *   a param value needs to be obtained for a request (unless the param was overridden). The
 *   function will be passed the current data value as an argument.
 *
 *   Each key value in the parameter object is first bound to url template if present and then any
 *   excess keys are appended to the url search query after the `?`.
 *
 *   Given a template `/path/:verb` and parameter `{verb: 'greet', salutation: 'Hello'}` results in
 *   URL `/path/greet?salutation=Hello`.
 *
 *   If the parameter value is prefixed with `@`, then the value for that parameter will be
 *   extracted from the corresponding property on the `data` object (provided when calling actions
 *   with a request body).
 *   For example, if the `defaultParam` object is `{someParam: '@someProp'}` then the value of
 *   `someParam` will be `data.someProp`.
 *   Note that the parameter will be ignored, when calling a "GET" action method (i.e. an action
 *   method that does not accept a request body).
 *
 * @param {Object.<Object>=} actions Hash with declaration of custom actions that will be available
 *   in addition to the default set of resource actions (see below). If a custom action has the same
 *   key as a default action (e.g. `save`), then the default action will be *overwritten*, and not
 *   extended.
 *
 *   The declaration should be created in the format of {@link ng.$http#usage $http.config}:
 *
 *       {
 *         action1: {method:?, params:?, isArray:?, headers:?, ...},
 *         action2: {method:?, params:?, isArray:?, headers:?, ...},
 *         ...
 *       }
 *
 *   Where:
 *
 *   - **`action`** – {string} – The name of action. This name becomes the name of the method on
 *     your resource object.
 *   - **`method`** – {string} – Case insensitive HTTP method (e.g. `GET`, `POST`, `PUT`,
 *     `DELETE`, `JSONP`, etc).
 *   - **`params`** – {Object=} – Optional set of pre-bound parameters for this action. If any of
 *     the parameter value is a function, it will be called every time when a param value needs to
 *     be obtained for a request (unless the param was overridden). The function will be passed the
 *     current data value as an argument.
 *   - **`url`** – {string} – Action specific `url` override. The url templating is supported just
 *     like for the resource-level urls.
 *   - **`isArray`** – {boolean=} – If true then the returned object for this action is an array,
 *     see `returns` section.
 *   - **`transformRequest`** –
 *     `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
 *     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.
 *     By default, transformRequest will contain one function that checks if the request data is
 *     an object and serializes it using `angular.toJson`. To prevent this behavior, set
 *     `transformRequest` to an empty array: `transformRequest: []`
 *   - **`transformResponse`** –
 *     `{function(data, headersGetter, status)|Array.<function(data, headersGetter, status)>}` –
 *     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.
 *     By default, transformResponse will contain one function that checks if the response looks
 *     like a JSON string and deserializes it using `angular.fromJson`. To prevent this behavior,
 *     set `transformResponse` to an empty array: `transformResponse: []`
 *   - **`cache`** – `{boolean|Cache}` – A boolean value or object created with
 *     {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.
 *     See {@link $http#caching $http Caching} for more information.
 *   - **`timeout`** – `{number}` – Timeout in milliseconds.<br />
 *     **Note:** In contrast to {@link ng.$http#usage $http.config}, {@link ng.$q promises} are
 *     **not** supported in `$resource`, because the same value would be used for multiple requests.
 *     If you are looking for a way to cancel requests, you should use the `cancellable` option.
 *   - **`cancellable`** – `{boolean}` – If true, the request made by a "non-instance" call will be
 *     cancelled (if not already completed) by calling `$cancelRequest()` on the call's return
 *     value. Calling `$cancelRequest()` for a non-cancellable or an already completed/cancelled
 *     request will have no effect.
 *   - **`withCredentials`** – `{boolean}` – Whether to set the `withCredentials` flag on the
 *     XHR object. See
 *     [XMLHttpRequest.withCredentials](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/withCredentials)
 *     for more information.
 *   - **`responseType`** – `{string}` – See
 *     [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/responseType).
 *   - **`interceptor`** – `{Object=}` – The interceptor object has four optional methods -
 *     `request`, `requestError`, `response`, and `responseError`. See
 *     {@link ng.$http#interceptors $http interceptors} for details. Note that
 *     `request`/`requestError` interceptors are applied before calling `$http`, thus before any
 *     global `$http` interceptors. Also, rejecting or throwing an error inside the `request`
 *     interceptor will result in calling the `responseError` interceptor.
 *     The resource instance or collection is available on the `resource` property of the
 *     `http response` object passed to `response`/`responseError` interceptors.
 *     Keep in mind that the associated promise will be resolved with the value returned by the
 *     response interceptors. Make sure you return an appropriate value and not the `response`
 *     object passed as input. For reference, the default `response` interceptor (which gets applied
 *     if you don't specify a custom one) returns `response.resource`.<br />
 *     See {@link ngResource.$resource#using-interceptors below} for an example of using
 *     interceptors in `$resource`.
 *   - **`hasBody`** – `{boolean}` – If true, then the request will have a body.
 *     If not specified, then only POST, PUT and PATCH requests will have a body. *
 * @param {Object} options Hash with custom settings that should extend the
 *   default `$resourceProvider` behavior.  The supported options are:
 *
 *   - **`stripTrailingSlashes`** – {boolean} – If true then the trailing
 *   slashes from any calculated URL will be stripped. (Defaults to true.)
 *   - **`cancellable`** – {boolean} – If true, the request made by a "non-instance" call will be
 *   cancelled (if not already completed) by calling `$cancelRequest()` on the call's return value.
 *   This can be overwritten per action. (Defaults to false.)
 *
 * @returns {Object} A resource "class" object with methods for the default set of resource actions
 *   optionally extended with custom `actions`. The default set contains these actions:
 *   ```js
 *   {
 *     'get':    {method: 'GET'},
 *     'save':   {method: 'POST'},
 *     'query':  {method: 'GET', isArray: true},
 *     'remove': {method: 'DELETE'},
 *     'delete': {method: 'DELETE'}
 *   }
 *   ```
 *
 *   Calling these methods invoke {@link ng.$http} with the specified http method, destination and
 *   parameters. When the data is returned from the server then the object is an instance of the
 *   resource class. The actions `save`, `remove` and `delete` are available on it as methods with
 *   the `$` prefix. This allows you to easily perform CRUD operations (create, read, update,
 *   delete) on server-side data like this:
 *   ```js
 *   var User = $resource('/user/:userId', {userId: '@id'});
 *   User.get({userId: 123}).$promise.then(function(user) {
 *     user.abc = true;
 *     user.$save();
 *   });
 *   ```
 *
 *   It is important to realize that invoking a `$resource` object method immediately returns an
 *   empty reference (object or array depending on `isArray`). Once the data is returned from the
 *   server the existing reference is populated with the actual data. This is a useful trick since
 *   usually the resource is assigned to a model which is then rendered by the view. Having an empty
 *   object results in no rendering, once the data arrives from the server then the object is
 *   populated with the data and the view automatically re-renders itself showing the new data. This
 *   means that in most cases one never has to write a callback function for the action methods.
 *
 *   The action methods on the class object or instance object can be invoked with the following
 *   parameters:
 *
 *   - "class" actions without a body: `Resource.action([parameters], [success], [error])`
 *   - "class" actions with a body: `Resource.action([parameters], postData, [success], [error])`
 *   - instance actions: `instance.$action([parameters], [success], [error])`
 *
 *
 *   When calling instance methods, the instance itself is used as the request body (if the action
 *   should have a body). By default, only actions using `POST`, `PUT` or `PATCH` have request
 *   bodies, but you can use the `hasBody` configuration option to specify whether an action
 *   should have a body or not (regardless of its HTTP method).
 *
 *
 *   Success callback is called with (value (Object|Array), responseHeaders (Function),
 *   status (number), statusText (string)) arguments, where `value` is the populated resource
 *   instance or collection object. The error callback is called with (httpResponse) argument.
 *
 *   Class actions return an empty instance (with the additional properties listed below).
 *   Instance actions return a promise for the operation.
 *
 *   The Resource instances and collections have these additional properties:
 *
 *   - `$promise`: The {@link ng.$q promise} of the original server interaction that created this
 *     instance or collection.
 *
 *     On success, the promise is resolved with the same resource instance or collection object,
 *     updated with data from server. This makes it easy to use in the
 *     {@link ngRoute.$routeProvider `resolve` section of `$routeProvider.when()`} to defer view
 *     rendering until the resource(s) are loaded.
 *
 *     On failure, the promise is rejected with the {@link ng.$http http response} object.
 *
 *     If an interceptor object was provided, the promise will instead be resolved with the value
 *     returned by the response interceptor (on success) or responceError interceptor (on failure).
 *
 *   - `$resolved`: `true` after first server interaction is completed (either with success or
 *      rejection), `false` before that. Knowing if the Resource has been resolved is useful in
 *      data-binding. If there is a response/responseError interceptor and it returns a promise,
 *      `$resolved` will wait for that too.
 *
 *   The Resource instances and collections have these additional methods:
 *
 *   - `$cancelRequest`: If there is a cancellable, pending request related to the instance or
 *      collection, calling this method will abort the request.
 *
 *   The Resource instances have these additional methods:
 *
 *   - `toJSON`: It returns a simple object without any of the extra properties added as part of
 *     the Resource API. This object can be serialized through {@link angular.toJson} safely
 *     without attaching AngularJS-specific fields. Notice that `JSON.stringify` (and
 *     `angular.toJson`) automatically use this method when serializing a Resource instance
 *     (see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#toJSON%28%29_behavior)).
 *
 * @example
 *
 * ### Basic usage
 *
   ```js
     // Define a CreditCard class
     var CreditCard = $resource('/users/:userId/cards/:cardId',
       {userId: 123, cardId: '@id'}, {
         charge: {method: 'POST', params: {charge: true}}
       });

     // We can retrieve a collection from the server
     var cards = CreditCard.query();
         // GET: /users/123/cards
         // server returns: [{id: 456, number: '1234', name: 'Smith'}]

     // Wait for the request to complete
     cards.$promise.then(function() {
       var card = cards[0];

       // Each item is an instance of CreditCard
       expect(card instanceof CreditCard).toEqual(true);

       // Non-GET methods are mapped onto the instances
       card.name = 'J. Smith';
       card.$save();
           // POST: /users/123/cards/456 {id: 456, number: '1234', name: 'J. Smith'}
           // server returns: {id: 456, number: '1234', name: 'J. Smith'}

       // Our custom method is mapped as well (since it uses POST)
       card.$charge({amount: 9.99});
           // POST: /users/123/cards/456?amount=9.99&charge=true {id: 456, number: '1234', name: 'J. Smith'}
     });

     // We can create an instance as well
     var newCard = new CreditCard({number: '0123'});
     newCard.name = 'Mike Smith';

     var savePromise = newCard.$save();
         // POST: /users/123/cards {number: '0123', name: 'Mike Smith'}
         // server returns: {id: 789, number: '0123', name: 'Mike Smith'}

     savePromise.then(function() {
       // Once the promise is resolved, the created instance
       // is populated with the data returned by the server
       expect(newCard.id).toEqual(789);
     });
   ```
 *
 * The object returned from a call to `$resource` is a resource "class" which has one "static"
 * method for each action in the definition.
 *
 * Calling these methods invokes `$http` on the `url` template with the given HTTP `method`,
 * `params` and `headers`.
 *
 * @example
 *
 * ### Accessing the response
 *
 * When the data is returned from the server then the object is an instance of the resource type and
 * all of the non-GET methods are available with `$` prefix. This allows you to easily support CRUD
 * operations (create, read, update, delete) on server-side data.
 *
   ```js
     var User = $resource('/users/:userId', {userId: '@id'});
     User.get({userId: 123}).$promise.then(function(user) {
       user.abc = true;
       user.$save();
     });
   ```
 *
 * It's worth noting that the success callback for `get`, `query` and other methods gets called with
 * the resource instance (populated with the data that came from the server) as well as an `$http`
 * header getter function, the HTTP status code and the response status text. So one could rewrite
 * the above example and get access to HTTP headers as follows:
 *
   ```js
     var User = $resource('/users/:userId', {userId: '@id'});
     User.get({userId: 123}, function(user, getResponseHeaders) {
       user.abc = true;
       user.$save(function(user, putResponseHeaders) {
         // `user` => saved `User` object
         // `putResponseHeaders` => `$http` header getter
       });
     });
   ```
 *
 * @example
 *
 * ### Creating custom actions
 *
 * In this example we create a custom method on our resource to make a PUT request:
 *
   ```js
      var app = angular.module('app', ['ngResource']);

      // Some APIs expect a PUT request in the format URL/object/ID
      // Here we are creating an 'update' method
      app.factory('Notes', ['$resource', function($resource) {
        return $resource('/notes/:id', {id: '@id'}, {
          update: {method: 'PUT'}
        });
      }]);

      // In our controller we get the ID from the URL using `$location`
      app.controller('NotesCtrl', ['$location', 'Notes', function($location, Notes) {
        // First, retrieve the corresponding `Note` object from the server
        // (Assuming a URL of the form `.../notes?id=XYZ`)
        var noteId = $location.search().id;
        var note = Notes.get({id: noteId});

        note.$promise.then(function() {
          note.content = 'Hello, world!';

          // Now call `update` to save the changes on the server
          Notes.update(note);
              // This will PUT /notes/ID with the note object as the request payload

          // Since `update` is a non-GET method, it will also be available on the instance
          // (prefixed with `$`), so we could replace the `Note.update()` call with:
          //note.$update();
        });
      }]);
   ```
 *
 * @example
 *
 * ### Cancelling requests
 *
 * If an action's configuration specifies that it is cancellable, you can cancel the request related
 * to an instance or collection (as long as it is a result of a "non-instance" call):
 *
   ```js
     // ...defining the `Hotel` resource...
     var Hotel = $resource('/api/hotels/:id', {id: '@id'}, {
       // Let's make the `query()` method cancellable
       query: {method: 'get', isArray: true, cancellable: true}
     });

     // ...somewhere in the PlanVacationController...
     ...
     this.onDestinationChanged = function onDestinationChanged(destination) {
       // We don't care about any pending request for hotels
       // in a different destination any more
       if (this.availableHotels) {
         this.availableHotels.$cancelRequest();
       }

       // Let's query for hotels in `destination`
       // (calls: /api/hotels?location=<destination>)
       this.availableHotels = Hotel.query({location: destination});
     };
   ```
 *
 * @example
 *
 * ### Using interceptors
 *
 * You can use interceptors to transform the request or response, perform additional operations, and
 * modify the returned instance/collection. The following example, uses `request` and `response`
 * interceptors to augment the returned instance with additional info:
 *
   ```js
     var Thing = $resource('/api/things/:id', {id: '@id'}, {
       save: {
         method: 'POST',
         interceptor: {
           request: function(config) {
             // Before the request is sent out, store a timestamp on the request config
             config.requestTimestamp = Date.now();
             return config;
           },
           response: function(response) {
             // Get the instance from the response object
             var instance = response.resource;

             // Augment the instance with a custom `saveLatency` property, computed as the time
             // between sending the request and receiving the response.
             instance.saveLatency = Date.now() - response.config.requestTimestamp;

             // Return the instance
             return instance;
           }
         }
       }
     });

     Thing.save({foo: 'bar'}).$promise.then(function(thing) {
       console.log('That thing was saved in ' + thing.saveLatency + 'ms.');
     });
   ```

     * @description
     * Object containing default options used when creating `$resource` instances.
     *
     * The default values satisfy a wide range of usecases, but you may choose to overwrite any of
     * them to further customize your instances. The available properties are:
     *
     * - **stripTrailingSlashes** – `{boolean}` – If true, then the trailing slashes from any
     *   calculated URL will be stripped.<br />
     *   (Defaults to true.)
     * - **cancellable** – `{boolean}` – If true, the request made by a "non-instance" call will be
     *   cancelled (if not already completed) by calling `$cancelRequest()` on the call's return
     *   value. For more details, see {@link ngResource.$resource}. This can be overwritten per
     *   resource class or action.<br />
     *   (Defaults to false.)
     * - **actions** - `{Object.<Object>}` - A hash with default actions declarations. Actions are
     *   high-level methods corresponding to RESTful actions/methods on resources. An action may
     *   specify what HTTP method to use, what URL to hit, if the return value will be a single
     *   object or a collection (array) of objects etc. For more details, see
     *   {@link ngResource.$resource}. The actions can also be enhanced or overwritten per resource
     *   class.<br />
     *   The default actions are:
