Detailed Description

Observer interface.

This interface represents the concept of an observer as defined in the Design Pattern. An observer is attached to an observable (IObservable) via the IObservable::attachObserver() method and detached by IObservable::detachObserver(). The observable notifies it of a change by calling the observerUpdate() method.

An observer can only be attached to one observable at a time

The methods of this class must only be called by IObservable and never directly by the user.
