-/**
- * @workInProgress
- * @ngdoc service
- * @name angular.service.$updateView
- * @requires $browser
- *
- * @description
- * Calling `$updateView` enqueues the eventual update of the view. (Update the DOM to reflect the
- * model). The update is eventual, since there are often multiple updates to the model which may
- * be deferred. The default update delayed is 25 ms. This means that the view lags the model by
- * that time. (25ms is small enough that it is perceived as instantaneous by the user). The delay
- * can be adjusted by setting the delay property of the service.
- *
- * <pre>angular.service('$updateView').delay = 10</pre>
- *
- * The delay is there so that multiple updates to the model which occur sufficiently close
- * together can be merged into a single update.
- *
- * You don't usually call '$updateView' directly since angular does it for you in most cases,
- * but there are some cases when you need to call it.
- *
- * - `$updateView()` called automatically by angular:
- * - Your Application Controllers: Your controller code is called by angular and hence
- * angular is aware that you may have changed the model.
- * - Your Services: Your service is usually called by your controller code, hence same rules
- * apply.
- * - May need to call `$updateView()` manually:
- * - Widgets / Directives: If you listen to any DOM events or events on any third party
- * libraries, then angular is not aware that you may have changed state state of the
- * model, and hence you need to call '$updateView()' manually.
- * - 'setTimeout'/'XHR': If you call 'setTimeout' (instead of {@link angular.service.$defer})
- * or 'XHR' (instead of {@link angular.service.$xhr}) then you may be changing the model
- * without angular knowledge and you may need to call '$updateView()' directly.
- *
- * Note: if you wish to update the view immediately (without delay), you can do so by calling
- * {@link angular.scope.$apply} at any time from your code:
- * <pre>scope.$apply()</pre>
- *
- * In unit-test mode the update is instantaneous and synchronous to simplify writing tests.
