Class java.util.concurrent.ThreadPoolExecutor

Examples of java.util.concurrent.ThreadPoolExecutor.shutdown()

java.util.concurrent.ThreadPoolExecutor.shutdown()
Initiates an orderly shutdown in which previously submitted tasks are executed, but no new tasks will be accepted. Invocation has no additional effect if already shut down.
This method does not wait for previously submitted tasks to complete execution. Use {@link #awaitTermination awaitTermination}to do that. @throws SecurityException {@inheritDoc}

        throws InterruptedException {
        FutureTask<?> client = new FutureTask<Object>(clientImpl, null);
        ThreadPoolExecutor tpe = new ThreadPoolExecutor(1, 1, 10000L, TimeUnit.MILLISECONDS,
                new LinkedBlockingQueue<Runnable>());
        tpe.execute(client);
        tpe.shutdown();
        tpe.awaitTermination(timeOut, timeUnit);
        if (!client.isDone()) {
            return false;
        }
        return true;
