This is an abstract observable class to implement the Observer design pattern. It is extended by JEventDispatcher which is instantiated by JApplication. JObservable is a subclass of JObject.

The Observer design pattern provides the possibility of having observable objects raising events triggered through the Event Dispatcher. |Observers can be attached to an instance of an Observable so that they can be notified when specific events occur during the life-cycle of this particular object.
