/**
 * @ngdoc service
 * @name $mdDialog
 * @module material.components.dialog
 *
 * @description
 * `$mdDialog` opens a dialog over the app to inform users about critical information or require
 *  them to make decisions. There are two approaches for setup: a simple promise API
 *  and regular object syntax.
 *
 * ## Restrictions
 *
 * - The dialog is always given an isolate scope.
 * - The dialog's template must have an outer `<md-dialog>` element.
 *   Inside, use an `<md-dialog-content>` element for the dialog's content, and use
 *   an `<md-dialog-actions>` element for the dialog's actions.
 * - Dialogs must cover the entire application to keep interactions inside of them.
 * Use the `parent` option to change where dialogs are appended.
 *
 * ## Sizing
 * - Complex dialogs can be sized with `flex="percentage"`, i.e. `flex="66"`.
 * - Default max-width is 80% of the `rootElement` or `parent`.
 *
 * ## CSS
 * - `.md-dialog-content` - class that sets the padding on the content as the spec file
 *
 * @usage
 * <hljs lang="html">
 * <div  ng-app="demoApp" ng-controller="EmployeeController">
 *   <div>
 *     <md-button ng-click="showAlert()" class="md-raised md-warn">
 *       Employee Alert!
 *       </md-button>
 *   </div>
 *   <div>
 *     <md-button ng-click="showDialog($event)" class="md-raised">

 *
 * ### JavaScript: object syntax
 * <hljs lang="js">
 * (function(angular, undefined){
 *   "use strict";
 *
 *   angular
 *    .module('demoApp', ['ngMaterial'])
 *    .controller('AppCtrl', AppController);
 *
 *   function AppController($scope, $mdDialog) {
 *     var alert;
 *     $scope.showAlert = showAlert;
 *     $scope.showDialog = showDialog;

 *         textContent: 'This is an example of how easy dialogs can be!',
 *         ok: 'Close'
 *       });
 *
 *       $mdDialog
 *         .show( alert )

 *        $mdDialog.show({
 *          parent: parentEl,
 *          targetEvent: $event,

 *            '      Close Dialog' +
 *            '    </md-button>' +
 *            '  </md-dialog-actions>' +
 *            '</md-dialog>',
 *          locals: {
 *            items: $scope.items
 *          },
 *          controller: DialogController
 *       });
 *       function DialogController($scope, $mdDialog, items) {
 *         $scope.items = items;
 *         $scope.closeDialog = function() {
 *           $mdDialog.hide();
 *         }
 *       }
 *     }
 *   }
 * })(angular);
 * </hljs>
 *
 * ### Multiple Dialogs
 * Using the `multiple` option for the `$mdDialog` service allows developers to show multiple dialogs
 * at the same time.
 *
 * <hljs lang="js">
 *   // From plain options
 *   $mdDialog.show({
 *     multiple: true
 *   });
 *
 *   // From a dialog preset
 *   $mdDialog.show(
 *     $mdDialog
 *       .alert()
 *       .multiple(true)
 *   );
 *
 * </hljs>
 *
 * ### Pre-Rendered Dialogs
 * By using the `contentElement` option, it is possible to use an already existing element in the DOM.
 *
 * > Pre-rendered dialogs will be not linked to any scope and will not instantiate any new controller.<br/>
 * > You can manually link the elements to a scope or instantiate a controller from the template (`ng-controller`)
 *
 * <hljs lang="js">
 *   $scope.showPrerenderedDialog = function() {
 *     $mdDialog.show({
 *       contentElement: '#myStaticDialog',
 *       parent: angular.element(document.body)
 *     });
 *   };
 * </hljs>
 *
 * When using a string as value, `$mdDialog` will automatically query the DOM for the specified CSS selector.
 *
 * <hljs lang="html">
 *   <div style="visibility: hidden">
 *     <div class="md-dialog-container" id="myStaticDialog">
 *       <md-dialog>
 *         This is a pre-rendered dialog.
 *       </md-dialog>
 *     </div>
 *   </div>
 * </hljs>
 *
 * **Notice**: It is important, to use the `.md-dialog-container` as the content element, otherwise the dialog
 * will not show up.
 *
 * It also possible to use a DOM element for the `contentElement` option.
 * - `contentElement: document.querySelector('#myStaticDialog')`
 * - `contentElement: angular.element(TEMPLATE)`
 *
 * When using a `template` as content element, it will be not compiled upon open.
 * This allows you to compile the element yourself and use it each time the dialog opens.
 *
 * ### Custom Presets
 * Developers are also able to create their own preset, which can be easily used without repeating
 * their options each time.
 *
 * <hljs lang="js">
 *   $mdDialogProvider.addPreset('testPreset', {
 *     options: function() {
 *       return {
 *         template:
 *           '<md-dialog>' +
 *             'This is a custom preset' +
 *           '</md-dialog>',
 *         controllerAs: 'dialog',
 *         bindToController: true,
 *         clickOutsideToClose: true,
 *         escapeToClose: true
 *       };
 *     }
 *   });
 * </hljs>
 *
 * After you created your preset at config phase, you can easily access it.
 *
 * <hljs lang="js">
 *   $mdDialog.show(
 *     $mdDialog.testPreset()
 *   );
 * </hljs>
 *
 * ### JavaScript: promise API syntax, custom dialog template
 * <hljs lang="js">
 * (function(angular, undefined){
 *   "use strict";
 *
 *   angular
 *     .module('demoApp', ['ngMaterial'])

 *
 *   // Fictitious Employee Editor to show how to use simple and complex dialogs.
 *
 *   function EmployeeEditor($scope, $mdDialog) {
 *     var alert;
 *
 *     $scope.showAlert = showAlert;
 *     $scope.closeAlert = closeAlert;
 *     $scope.showGreeting = showCustomGreeting;
 *
 *     $scope.hasAlert = function() { return !!alert };

 *     // reference to dialog instance
 *
 *     function showAlert() {
 *       alert = $mdDialog.alert()
 *         .title('Attention, ' + $scope.userName)
 *         .textContent('This is an example of how easy dialogs can be!')
 *         .ok('Close');
 *
 *       $mdDialog
 *           .show( alert )
 *           .finally(function() {
 *             alert = undefined;
 *           });
 *     }
 *
 *     // Close the specified dialog instance and resolve with 'finished' flag
 *     // Normally this is not needed, just use '$mdDialog.hide()' to close
 *     // the most recent dialog popup.

 *       $mdDialog.hide( alert, "finished" );
 *       alert = undefined;

 *            // post-show code here: DOM element focus, etc.
 *         }
 *     }
 *
 *     // Dialog #3 - Demonstrate use of ControllerAs and passing $scope to dialog
 *     //             Here we used ng-controller="GreetingController as vm" and

/**
 * @ngdoc method
 * @name $mdDialog#show
 *
 * @description
 * Show a dialog with the specified options.
 *
 * @param {object} optionsOrPreset Either provide an `$mdDialogPreset` returned from `alert()`, and
 * `confirm()`, or an options object with the following properties:
 *   - `templateUrl` - `{string=}`: The url of a template that will be used as the content
 *   of the dialog.
 *   - `template` - `{string=}`: HTML template to show in the dialog. This **must** be trusted HTML
 *      with respect to Angular's [$sce service](https://docs.angularjs.org/api/ng/service/$sce).
 *      This template should **never** be constructed with any kind of user input or user data.
 *   - `contentElement` - `{string|Element}`: Instead of using a template, which will be compiled each time a
 *     dialog opens, you can also use a DOM element.<br/>
 *     * When specifying an element, which is present on the DOM, `$mdDialog` will temporary fetch the element into
 *       the dialog and restores it at the old DOM position upon close.
 *     * When specifying a string, the string be used as a CSS selector, to lookup for the element in the DOM.
 *   - `autoWrap` - `{boolean=}`: Whether or not to automatically wrap the template with a
 *     `<md-dialog>` tag if one is not provided. Defaults to true. Can be disabled if you provide a
 *     custom dialog directive.
 *   - `targetEvent` - `{DOMClickEvent=}`: A click's event object. When passed in as an option,
 *     the location of the click will be used as the starting point for the opening animation
 *     of the the dialog.
 *   - `openFrom` - `{string|Element|object}`: The query selector, DOM element or the Rect object
 *     that is used to determine the bounds (top, left, height, width) from which the Dialog will
 *     originate.
 *   - `closeTo` - `{string|Element|object}`: The query selector, DOM element or the Rect object
 *     that is used to determine the bounds (top, left, height, width) to which the Dialog will
 *     target.
 *   - `scope` - `{object=}`: the scope to link the template / controller to. If none is specified,
 *     it will create a new isolate scope.
 *     This scope will be destroyed when the dialog is removed unless `preserveScope` is set to true.
 *   - `preserveScope` - `{boolean=}`: whether to preserve the scope when the element is removed. Default is false
 *   - `disableParentScroll` - `{boolean=}`: Whether to disable scrolling while the dialog is open.
 *     Default true.
 *   - `hasBackdrop` - `{boolean=}`: Whether there should be an opaque backdrop behind the dialog.
 *     Default true.
 *   - `clickOutsideToClose` - `{boolean=}`: Whether the user can click outside the dialog to
 *     close it. Default false.
 *   - `escapeToClose` - `{boolean=}`: Whether the user can press escape to close the dialog.
 *     Default true.
 *   - `focusOnOpen` - `{boolean=}`: An option to override focus behavior on open. Only disable if
 *     focusing some other way, as focus management is required for dialogs to be accessible.
 *     Defaults to true.
 *   - `controller` - `{function|string=}`: The controller to associate with the dialog. The controller
 *     will be injected with the local `$mdDialog`, which passes along a scope for the dialog.
 *   - `locals` - `{object=}`: An object containing key/value pairs. The keys will be used as names
 *     of values to inject into the controller. For example, `locals: {three: 3}` would inject
 *     `three` into the controller, with the value 3. If `bindToController` is true, they will be
 *     copied to the controller instead.
 *   - `bindToController` - `bool`: bind the locals to the controller, instead of passing them in.
 *   - `resolve` - `{function=}`: Similar to locals, except it takes as values functions that return promises, and the
 *      dialog will not open until all of the promises resolve.
 *   - `controllerAs` - `{string=}`: An alias to assign the controller to on the scope.
 *   - `parent` - `{element=}`: The element to append the dialog to. Defaults to appending
 *     to the root element of the application.
 *   - `onShowing` - `function(scope, element)`: Callback function used to announce the show() action is
 *     starting.
 *   - `onComplete` - `function(scope, element)`: Callback function used to announce when the show() action is
 *     finished.
 *   - `onRemoving` - `function(element, removePromise)`: Callback function used to announce the
 *      close/hide() action is starting. This allows developers to run custom animations
 *      in parallel with the close animations.
 *   - `fullscreen` `{boolean=}`: An option to toggle whether the dialog should show in fullscreen
 *      or not. Defaults to `false`.
 *   - `multiple` `{boolean=}`: An option to allow this dialog to display over one that's currently open.
 * @returns {promise} A promise that can be resolved with `$mdDialog.hide()` or
 * rejected with `$mdDialog.cancel()`.
