IView implementation.
In PureMVC, the View class assumes these responsibilities:
IMediator instances.IMediators.IMediators when they are registered or removed.INotification in the application.IObservers to an INotification's observer list.INotification.IObservers of a given INotification when it broadcast.See also

public function View()Constructor.
This IView implementation is a Singleton,
so you should not call the constructor
directly, but instead call the static Singleton
Factory method View.getInstance()
|
| getInstance | () | method |
public static function getInstance():IViewView Singleton Factory method.
ReturnsIView —
the Singleton instance of View
|
| hasMediator | () | method |
public function hasMediator(mediatorName:String):BooleanCheck if a Mediator is registered or not
ParametersmediatorName:String |
Boolean — whether a Mediator is registered with the given mediatorName.
|
| initializeView | () | method |
protected function initializeView():voidInitialize the Singleton View instance.
Called automatically by the constructor, this is your opportunity to initialize the Singleton instance in your subclass without overriding the constructor.
| notifyObservers | () | method |
public function notifyObservers(notification:INotification):void
Notify the IObservers for a particular INotification.
All previously attached IObservers for this INotification's
list are notified and are passed a reference to the INotification in
the order in which they were registered.
notification:INotification — the INotification to notify IObservers of.
|
| registerMediator | () | method |
public function registerMediator(mediator:IMediator):void
Register an IMediator instance with the View.
Registers the IMediator so that it can be retrieved by name,
and further interrogates the IMediator for its
INotification interests.
If the IMediator returns any INotification
names to be notified about, an Observer is created encapsulating
the IMediator instance's handleNotification method
and registering it as an Observer for all INotifications the
IMediator is interested in.
mediator:IMediator — the name to associate with this IMediator instance
|
| registerObserver | () | method |
public function registerObserver(notificationName:String, observer:IObserver):void
Register an IObserver to be notified
of INotifications with a given name.
notificationName:String — the name of the INotifications to notify this IObserver of
|
|
observer:IObserver — the IObserver to register
|
| removeMediator | () | method |
public function removeMediator(mediatorName:String):IMediator
Remove an IMediator from the View.
mediatorName:String — name of the IMediator instance to be removed.
|
IMediator —
the IMediator that was removed from the View
|
| removeObserver | () | method |
public function removeObserver(notificationName:String, notifyContext:Object):voidRemove the observer for a given notifyContext from an observer list for a given Notification name.
Parameters
notificationName:String — which observer list to remove from
|
|
notifyContext:Object — remove the observer with this object as its notifyContext
|
| retrieveMediator | () | method |
public function retrieveMediator(mediatorName:String):IMediator
Retrieve an IMediator from the View.
mediatorName:String — the name of the IMediator instance to retrieve.
|
IMediator —
the IMediator instance previously registered with the given mediatorName.
|
| SINGLETON_MSG | constant |
protected const SINGLETON_MSG:String = "View Singleton already constructed!"
