Class SynchronousChangeListener<T>

java.lang.Object

com.neurosys.events.AbstractChainChangeListener<T>

com.neurosys.events.SynchronousChangeListener<T>

All Implemented Interfaces:

ChangeGenerator<T>, ChangeListener<T>, Serializable, EventListener, org.apache.commons.collections.Transformer

public class SynchronousChangeListener<T>
extends AbstractChainChangeListener<T>

A wrapper ChangeListener and Transformer that in turn executes other ChangeListeners, listening to it. Hence making it also an intermediate ChangeGenerator that propagates the event it was listening to. During the propagation, onChange(ChangeGenerator, Object) will propagate the origin ChangeGenerator.
