      • awaitUninterruptibly

        public void awaitUninterruptibly()
        Description copied from interface: WaitQueue.Signal
        Wait, without throwing InterruptedException, until signalled. On exit isSignalled() must be true. If the thread is interrupted in the meantime, the interrupted flag will be set.
        Specified by:
        awaitUninterruptibly in interface WaitQueue.Signal

      • await

        public void await()
           throws java.lang.InterruptedException
        Description copied from interface: WaitQueue.Signal
        Wait until signalled, or throw an InterruptedException if interrupted before this happens. On normal exit isSignalled() must be true; however if InterruptedException is thrown isCancelled() will be true.
        Specified by:
        await in interface WaitQueue.Signal
        Throws:
        java.lang.InterruptedException

      • awaitUntil

        public boolean awaitUntil​(long until)
                   throws java.lang.InterruptedException
        Description copied from interface: WaitQueue.Signal
        Wait until signalled, or the provided time is reached, or the thread is interrupted. If signalled, isSignalled() will be true on exit, and the method will return true; if timedout, the method will return false and isCancelled() will be true; if interrupted an InterruptedException will be thrown and isCancelled() will be true.
        Specified by:
        awaitUntil in interface WaitQueue.Signal
        Parameters:
        until - System.nanoTime() to wait until
        Returns:
        true if signalled, false if timed out
        Throws:
        java.lang.InterruptedException

      • awaitUntilUninterruptibly

        public boolean awaitUntilUninterruptibly​(long until)
        Description copied from interface: WaitQueue.Signal
        Wait until signalled, or the provided time is reached, or the thread is interrupted. If signalled, isSignalled() will be true on exit, and the method will return true; if timedout, the method will return false and isCancelled() will be true
        Specified by:
        awaitUntilUninterruptibly in interface WaitQueue.Signal
        Parameters:
        until - System.nanoTime() to wait until
        Returns:
        true if signalled, false if timed out
