Class LockMonitor

java.lang.Object
  org.jboss.monitor.LockMonitor

All Implemented Interfaces:

Serializable

public class LockMonitor
extends Object
implements Serializable

Simple thread-safe POJO encapsulating locking stats. Turned this class to Serializable to be able to return copies of instances of this class over RMI. In this case it becomes detached from the EntityLockMonitor factory.
