Examples of CountDown

EDU.oswego.cs.dl.util.concurrent.CountDown
void main() { CountDown done = new CountDown(N); for (int i = 0; i < N; ++i) new Thread(new Worker(done)).start(); doSomethingElse(); done.acquire(); // wait for all to finish } }
[ Introduction to this package. ]
com.jayway.awaitility.support.CountDown
com.volantis.shared.time.Countdown
An abstraction of a clock that counts down.
org.elasticsearch.common.util.concurrent.CountDown
A simple thread safe count-down class that in contrast to a {@link CountDownLatch}never blocks. This class is useful if a certain action has to wait for N concurrent tasks to return or a timeout to occur in order to proceed.
