Class RecursiveModelListener

java.lang.Object
  org.deduced.RecursiveModelListener

All Implemented Interfaces:

java.util.EventListener, PropertyListener<java.lang.Object,java.lang.Object>

public class RecursiveModelListener
extends java.lang.Object
implements PropertyListener<java.lang.Object,java.lang.Object>

This class listens to a model and all its owned child recursively. When a change to one of them occurs, the linked listener is triggered with the event.
