Detailed Description

Methods to override: NONE This class implements the Observer design pattern defining Observable objects, when a class extends Observable Observers can be attached to the class listening for some event. When an event is detected in any method of the derived class the method can call notifyAll($event,$msg) to notify all the observers listening for event $event. The Observer objects must extend the Observer class and define the notify($event,$msg) method.
