Example 1 with DelayedQueue

use of com.firenio.collection.DelayedQueue in project baseio by generallycloud.

the class NioEventLoop method run.

@Override
public void run() {
    // does it useful to set variables locally ?
    final long idle = group.getIdleTime();
    final AtomicInteger selecting = this.selecting;
    final BlockingQueue<Runnable> events = this.events;
    final DelayedQueue dq = this.delayed_queue;
    long last_idle_time = Util.now();
    long next_idle_time = last_idle_time + idle;
    long select_time = idle;
    for (; ; ) {
        // restart will create a new event loop instead.
        if (!isRunning()) {
            shutdown();
            return;
        }
        try {
            // the method selector.wakeup is a weight operator, so we use flag "has_task"
            // and race flag "selecting" to reduce execution times of wake up
            // I am not sure events.size if a better way to instead of has_task?
            // example method selector.select(...) may throw an io exception
            // and if we need to try with the method to do something when exception caught?
            int selected;
            if (!has_task() && selecting.compareAndSet(0, 1)) {
                if (has_task()) {
                    selected = select_now();
                } else {
                    selected = select(select_time);

            } else {
                select_time = next_idle_time - Util.now();

    q.offer(new TestDelayTask(10));
    q.offer(new TestDelayTask(5));
