use of org.jgroups.util.Table in project JGroups by belaban.

the class TableStressTest method main.

public static void main(String[] args) throws InterruptedException {
    for (int i = 0; i < args.length; i++) {
        if (args[i].startsWith("-h")) {
            System.out.println("TableStressTest [-num numbers] [-adders <number of adder threads>]");
            return;
        }
        if (args[i].equals("-num")) {
            NUM = Integer.parseInt(args[++i]);
            continue;
        }
        if (args[i].equals("-adders")) {
            NUM_THREADS = Integer.parseInt(args[++i]);
        }
    }
    Table<Integer> buf = new Table<>(10000, 10240, 0);
    final CountDownLatch latch = new CountDownLatch(1);
    Remover remover = new Remover(buf, latch);
    remover.start();
    Adder[] adders = new Adder[NUM_THREADS];
    for (int i = 0; i < adders.length; i++) {
        adders[i] = new Adder(buf, latch, added);
        adders[i].start();
    }
    long start = System.currentTimeMillis();
    latch.countDown();
    while (remover.isAlive()) {
        System.out.println("added messages: " + added + ", removed messages: " + removed);
        remover.join(2000);
