Method Detail

decrement

public void decrement()

Description copied from interface: CountDownLatch

Count down by 1, signalling waiters if we have reached zero

Specified by:

decrement in interface CountDownLatch

count

public int count()

Specified by:

count in interface CountDownLatch

Returns:

the current count

isSignalled

protected boolean isSignalled()

Description copied from class: Awaitable.AsyncAwaitable

Return true once signalled. Unidirectional; once true, must never again be false.

Specified by:

isSignalled in class Awaitable.AsyncAwaitable
