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

com.hazelcast.core.ICountDownLatch.trySetCount()
Sets the count to the given value if the current count is zero.
If count is not zero then this method does nothing and returns {@code false}. @param count the number of times {@link #countDown} must be invokedbefore threads can pass through {@link #await} @return {@code true} if the new count was set or {@code false} if the currentcount is not zero @throws IllegalArgumentException if {@code count} is negative
