Class CompositeListener

java.lang.Object

com.jamonapi.CompositeListener

All Implemented Interfaces:

JAMonListener, DetailData, Serializable, EventListener

public class CompositeListener
extends Object
implements JAMonListener, DetailData

A class that can contain other listeners that can listen to jamon events of interest. These classes will all implement the JAMonListener interface too. This is an example of the Gang of 4 Composite design pattern.
