Type Parameters:

T - Listener interface.

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.lang.Iterable<T>, java.lang.reflect.InvocationHandler, java.util.Collection<T>, java.util.Set<T>

public class ListenerSet<T>
extends java.util.HashSet<T>
implements java.lang.reflect.InvocationHandler

Provides a thread-safe way to store and process listeners. Listener set takes in the defining listener interface and allows you to invoke the defined method upon the whole group via a getProxy().
