Detailed Description

template<class T>
class util::EventListener< T >

An interface for classes that are going to listen events from an event source.

An event can be of any type, and it is wise to write a custom event class for each event listener type to avoid confusion. If, for example, two event sources fire int events, then the listeners may be confused. Possible confusions can be solved by inspecting the source of the event, but this is not an elegant solution.

Public Methods
virtual void	eventOccured (EventSource< T > *source, const T &event)=0
	Called by EventSource whenever an event occurs.
