Class DelegatingNodeListener

java.lang.Object

org.jppf.node.event.NodeLifeCycleListenerAdapter

org.jppf.node.screensaver.DelegatingNodeListener

All Implemented Interfaces:

EventListener, NodeLifeCycleListener

public class DelegatingNodeListener
extends NodeLifeCycleListenerAdapter

This class registers as a NodeLifeCycleListener and instantiates an implementation of NodeIntegration, if any is defined in the configuration. It also registers this implementation as a TaskExecutionListener with the node, so it can receive a notification for each individual task reaches completion.
