Method Detail

awaitUninterruptibly

public void awaitUninterruptibly()

Behaves the same way as CountDownLatch.await() except it never throws InterruptedException. Thread interrupt status will be preserved if thread have been interrupted inside this method.

awaitUninterruptibly

public boolean awaitUninterruptibly(long timeout,
                                    TimeUnit unit)

Behaves the same way as CountDownLatch.await(long,TimeUnit) except it never throws InterruptedException. Thread interrupt status will be preserved if thread have been interrupted inside this method.

Parameters:

timeout - the maximum time to wait

unit - the time unit of the timeout argument

Returns:

true if the count reached zero and false if the waiting time elapsed before the count reached zero
