Causes the current thread to wait until the latch has counted down to zero, unless the thread is Thread#interrupt interrupted , or the specified waiting time elapses.

Usage

From source file:io.fabric8.msg.jnatsd.JNatsd.java

public void stop() throws Exception {
    if (started.compareAndSet(true, false)) {
        pingPong.stop();/* ww  w .java  2 s  .  com*/
