goog.a11y.aria.Announcer

Invokes a callback function when this object is disposed. Callbacks are invoked in the order in which they were added. If a callback is added to an already disposed Disposable, it will be called immediately.

Disposes of the object and its resources.

Performs appropriate cleanup. See description of goog.disposable.IDisposable for examples. Classes that extend goog.Disposable should override this method. Not reentrant. To avoid calling it twice, it must only be called from the subclass' disposeInternal method. Everywhere else the public dispose method must be used. For example:

 mypackage.MyClass = function() {
 mypackage.MyClass.base(this, 'constructor');
     // Constructor logic specific to MyClass.
     ...
   };
   goog.inherits(mypackage.MyClass, goog.Disposable);

   mypackage.MyClass.prototype.disposeInternal = function() {
     // Dispose logic specific to MyClass.
     ...
     // Call superclass's disposeInternal at the end of the subclass's, like
     // in C++, to avoid hard-to-catch issues.
     mypackage.MyClass.base(this, 'disposeInternal');
   };
 

Returns the id value for an aria-live region for a given priority.

Associates a disposable object with this object so that they will be disposed together.

Announce a message to be read by any assistive technologies the user may have active.

If monitoring the goog.Disposable instances is enabled, stores the creation stack trace of the Disposable instance.
