Examples with IMap com.hazelcast.map.IMap used on opensource projects

Example 1 with IMap

use of com.hazelcast.map.IMap in project hazelcast by hazelcast.

the class ClientXATest method testParallel.

@Test
public void testParallel() throws Exception {
    Hazelcast.newHazelcastInstance();
    final HazelcastInstance client = HazelcastClient.newHazelcastClient();
    // this is needed due to a racy bug in atomikos
    txn(client);
    int size = 100;
    ExecutorService executorService = Executors.newFixedThreadPool(5);
    final CountDownLatch latch = new CountDownLatch(size);
    for (int i = 0; i < size; i++) {
        executorService.execute(new Runnable() {

            public void run() {
                try {
                    txn(client);
                } catch (Exception e) {
                    logger.severe("Exception during txn", e);
                } finally {
                    latch.countDown();
                }
            }
        });
    }
    assertOpenEventually(latch, 20);
    final IMap m = client.getMap("m");
    for (int i = 0; i < 10; i++) {
        assertFalse(m.isLocked(i));
    }
}
