/**

 * @ngdoc service

 * @name $resource

 * @requires $http

 *

 * @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 parametrized 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 any of the parameter value is a function, it will be executed every time

 *   when a param value needs to be obtained for a request (unless the param was overridden).

 *

 *   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 an action method).  For

 *   example, if the `defaultParam` object is `{someParam: '@someProp'}` then the value of `someParam`

 *   will be `data.someProp`.

 *

 * @param {Object.<Object>=} actions Hash with declaration of custom action that should extend

 *   the default set of resource actions. 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 executed every time when a param value needs to

 *     be obtained for a request (unless the param was overridden).

 *   - **`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 to using `angular.toJson`. To prevent this behavior, set

 *     `transformRequest` to an empty array: `transformRequest: []`

 *   - **`transformResponse`** –

 *     `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –

 *     transform function or an array of such functions. The transform function takes the http

 *     response body and headers 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}` – 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/en/http_access_control#section_5)

 *     for more information.

 *   - **`responseType`** - `{string}` - see

 *     [requestType](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType).

 *   - **`interceptor`** - `{Object=}` - The interceptor object has two optional methods -

 *     `response` and `responseError`. Both `response` and `responseError` interceptors get called

 *     with `http response` object. See {@link ng.$http $http interceptors}.

 *

 * @param {Object} options Hash with custom settings that should extend the

 *   default `$resourceProvider` behavior.  The only supported option is

 *

 *   Where:

 *

 *   - **`stripTrailingSlashes`** – {boolean} – If true then the trailing

 *   slashes from any calculated URL will be stripped. (Defaults to true.)

 *

 * @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 an {@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'});

 *   var user = User.get({userId:123}, function() {

 *     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:

 *

 *   - HTTP GET "class" actions: `Resource.action([parameters], [success], [error])`

 *   - non-GET "class" actions: `Resource.action([parameters], postData, [success], [error])`

 *   - non-GET instance actions:  `instance.$action([parameters], [success], [error])`

 *

 *   Success callback is called with (value, responseHeaders) arguments. Error callback is called

 *   with (httpResponse) argument.

 *

 *   Class actions return empty instance (with additional properties below).

 *   Instance actions return promise of the action.

 *

 *   The Resource instances and collection 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

 *     {@link ngRoute.$routeProvider resolve section of $routeProvider.when()} to defer view

 *     rendering until the resource(s) are loaded.

 *

 *     On failure, the promise is resolved with the {@link ng.$http http response} object, without

 *     the `resource` property.

 *

 *     If an interceptor object was provided, the promise will instead be resolved with the value

 *     returned by the interceptor.

 *

 *   - `$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.

 *

 * @example

 *

 * # Credit card resource

 *

 * ```js

     // Define CreditCard class

     var CreditCard = $resource('/user/:userId/card/:cardId',

      {userId:123, cardId:'@id'}, {

       charge: {method:'POST', params:{charge:true}}

      });

     // We can retrieve a collection from the server

     var cards = CreditCard.query(function() {

       // GET: /user/123/card

       // server returns: [ {id:456, number:'1234', name:'Smith'} ];

       var card = cards[0];

       // each item is an instance of CreditCard

       expect(card instanceof CreditCard).toEqual(true);

       card.name = "J. Smith";

       // non GET methods are mapped onto the instances

       card.$save();

       // POST: /user/123/card/456 {id:456, number:'1234', name:'J. Smith'}

       // server returns: {id:456, number:'1234', name: 'J. Smith'};

       // our custom method is mapped as well.

       card.$charge({amount:9.99});

       // POST: /user/123/card/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";

     newCard.$save();

     // POST: /user/123/card {number:'0123', name:'Mike Smith'}

     // server returns: {id:789, number:'0123', name: 'Mike Smith'};

     expect(newCard.id).toEqual(789);

 * ```

 *

 * The object returned from this function execution is a resource "class" which has "static" method

 * for each action in the definition.

 *

 * Calling these methods invoke `$http` on the `url` template with the given `method`, `params` and

 * `headers`.

 * 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('/user/:userId', {userId:'@id'});

     User.get({userId:123}, function(user) {

       user.abc = true;

       user.$save();

     });

   ```

 *

 * It's worth noting that the success callback for `get`, `query` and other methods gets passed

 * in the response that came from the server as well as $http header getter function, so one

 * could rewrite the above example and get access to http headers as:

 *

   ```js

     var User = $resource('/user/:userId', {userId:'@id'});

     User.get({userId:123}, function(u, getResponseHeaders){

       u.abc = true;

       u.$save(function(u, putResponseHeaders) {

         //u => saved user object

         //putResponseHeaders => $http header getter

       });

     });

   ```

 *

 * You can also access the raw `$http` promise via the `$promise` property on the object returned

 *

   ```

     var User = $resource('/user/:userId', {userId:'@id'});

     User.get({userId:123})

         .$promise.then(function(user) {

           $scope.user = user;

         });

   ```

 * # Creating a custom 'PUT' request

 * In this example we create a custom method on our resource to make a PUT request

 * ```js

 *    var app = angular.module('app', ['ngResource', 'ngRoute']);

 *

 *    // 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', null,

 *        {

 *            'update': { method:'PUT' }

 *        });

 *    }]);

 *

 *    // In our controller we get the ID from the URL using ngRoute and $routeParams

 *    // We pass in $routeParams and our Notes factory along with $scope

 *    app.controller('NotesCtrl', ['$scope', '$routeParams', 'Notes',

                                      function($scope, $routeParams, Notes) {

 *    // First get a note object from the factory

 *    var note = Notes.get({ id:$routeParams.id });

 *    $id = note.id;

 *

 *    // Now call update passing in the ID first then the object you are updating

 *    Notes.update({ id:$id }, note);

 *

 *    // This will PUT /notes/ID with the note object in the request payload

 *    }]);

 * ```
