Class AbstractMulticaster<T>

java.lang.Object

org.freecompany.util.multicaster.AbstractMulticaster<T>

All Implemented Interfaces:

Multicaster<T>

Direct Known Subclasses:

DefaultMulticaster.Handler, NotificationMulticaster

public abstract class AbstractMulticaster<T>
extends java.lang.Object
implements Multicaster<T>

This is a generic abstract event multicaster based on the pattern of the AWTEventMulticaster. It's benefits are zero cost for all single listeners and near zero cost for a few more after that. Classes which commonly have greater than a few listeners may be better off using a standard collection with fast iteration.
