Class com.hazelcast.core.ICountDownLatch

Examples of com.hazelcast.core.ICountDownLatch.await()

com.hazelcast.core.ICountDownLatch.await()
Causes the current thread to wait until the latch has counted down to zero, an exception is thrown, or the specified waiting time elapses.

If the current count is zero then this method returns immediately with the value {@code true}.

If the current count is greater than zero then the current thread becomes disabled for thread scheduling purposes and lies dormant until one of five things happen:
- The count reaches zero due to invocations of the {@link #countDown} method;
- This ICountDownLatch instance is destroyed;
- The countdown owner becomes disconnected;
- Some other thread {@linkplain Thread#interrupt interrupts}the current thread; or
- The specified waiting time elapses.
If the count reaches zero then the method returns with the value {@code true}.

If the current thread:
- has its interrupted status set on entry to this method; or
- is {@linkplain Thread#interrupt interrupted} while waiting,
then {@link InterruptedException} is thrown and the current thread'sinterrupted status is cleared.
If the specified waiting time elapses then the value {@code false}is returned. If the time is less than or equal to zero, the method will not wait at all. @param timeout the maximum time to wait @param unit the time unit of the {@code timeout} argument @return {@code true} if the count reached zero and {@code false}if the waiting time elapsed before the count reached zero @throws InterruptedException if the current thread is interrupted @throws IllegalStateException if hazelcast instance is shutdown while waiting
