Class OwnerAwareReadLock

java.lang.Object
  java.util.concurrent.locks.ReentrantReadWriteLock.ReadLock
      org.entityfs.support.util.concurrent.locks.OwnerAwareReadLock

All Implemented Interfaces:

Serializable, Lock

public final class OwnerAwareReadLock
extends ReentrantReadWriteLock.ReadLock
implements Lock, Serializable

There's no way of getting information on which threads that hold it from Java's ReentrantReadWriteLock's read lock. This class extends ReentrantReadWriteLock's read lock to add that information.

This class also implement the Lock interface. ReentrantReadWriteLock.ReadLock does not do that.

Since:

1.0
