Class ConsoleListener

java.lang.Object
  org.jboss.cache.ConsoleListener

All Implemented Interfaces:: TreeCacheListener

public class ConsoleListener
extends Object
implements TreeCacheListener

This class provides a non-graphical view of JBossCache replication events for a replicated cache.

It can be utilized as a standalone application or as a component in other applications.

WARNING: take care when using this class in conjunction with transactionally replicated cache's as it can cause deadlock situations due to the reading of values for nodes in the cache.
