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.

Method	Description
__construct	Class constructor.
attach	Attach an Observer object.
detach	Detach an Observer object.
getState	Get the state of the Observable object.
notify	Update each attached Observer and return an array of their return values.
