Package org.puremvc.java.patterns.observer

Class Notifier

java.lang.Object
org.puremvc.java.patterns.observer.Notifier
All Implemented Interfaces:
INotifier
Direct Known Subclasses:
MacroCommand, Mediator, Proxy, SimpleCommand
public class Notifier
extends java.lang.Object
implements INotifier

A Base INotifier implementation.

MacroCommand, Command, Mediator and Proxy all have a need to send Notifications.

The INotifier interface provides a common method called sendNotification that relieves implementation code of the necessity to actually construct Notifications.

The Notifier class, which all of the above mentioned classes extend, provides an initialized reference to the Facade Singleton, which is required for the convienience method for sending Notifications, but also eases implementation as these classes have frequent Facade interactions and usually require access to the facade anyway.
