Class ReadLockOwnerAwareReentrantReadWriteLock

java.lang.Object
  java.util.concurrent.locks.ReentrantReadWriteLock
      org.entityfs.support.util.concurrent.locks.ReadLockOwnerAwareReentrantReadWriteLock

All Implemented Interfaces:

Serializable, ReadWriteLock

public class ReadLockOwnerAwareReentrantReadWriteLock
extends ReentrantReadWriteLock

There's no way of getting the information on which threads that hold the read lock from Java's ReentrantReadWriteLock. EntityFS substitutes ReentrantReadWriteLock for this implementation that adds that capability.

Since:

1.0
