Detailed Description

Concrete implementation of Observer calling a callback function.

albaObserverCallback is a class implementing an "observer" that launches a callback function. It's useful for attaching as observers objects that do not inherit from albaObserver. When an event is rise the callback function is called passing as argument some event content plus event source Data and this class ClientData, that can be set to any value. Usually ClientData is used to store the (self) pointer of the class to whom the callback function belongs.
