Class BooleanLatch

java.lang.Object
  java.util.concurrent.locks.AbstractOwnableSynchronizer
      java.util.concurrent.locks.AbstractQueuedSynchronizer
          com.sun.enterprise.v3.common.BooleanLatch

All Implemented Interfaces:

Serializable

public class BooleanLatch
extends AbstractQueuedSynchronizer

Acts like a CountDownLatch except that it only requires a single signal to fire. Because a latch is non-exclusive, it uses the shared acquire and release methods.
