@Test

    String lockName = newName();
    String conditionName = newName();
    final ILock lock = callerInstance.getLock(lockName);
    final ICondition condition = lock.newCondition(conditionName);

Example 17 with ILock

use of com.hazelcast.core.ILock in project hazelcast by hazelcast.

the class ConditionAbstractTest method testAwaitTimeout_whenSuccess.

@Test(timeout = 60000)
public void testAwaitTimeout_whenSuccess() throws InterruptedException {
    final ILock lock = callerInstance.getLock(newName());
    final ICondition condition = lock.newCondition(newName());
    final CountDownLatch locked = new CountDownLatch(1);
    final AtomicBoolean signalledCorrectly = new AtomicBoolean(false);
    new Thread(new Runnable() {

        @Override

                    signalledCorrectly.set(true);
                }
            } catch (InterruptedException e) {
                ignore(e);

        }
    }).start();
    locked.await();
    signal(lock, condition);
    assertAtomicEventually("awaiting thread should have been signalled", true, signalledCorrectly, THIRTY_SECONDS);
}

Example 18 with ILock

use of com.hazelcast.core.ILock in project hazelcast by hazelcast.

the class ConditionAbstractTest method testSignalIsNotStored.

// A signal send to wake up threads is not a flag set on the condition
// Threads calling await() after signal() has been called will hand on waiting.
@Test(timeout = 60000)
public void testSignalIsNotStored() throws InterruptedException {
    ILock lock = callerInstance.getLock(newName());
    ICondition condition = lock.newCondition(newName());
    CountDownLatch signalled = new CountDownLatch(1);
    signal(lock, condition);
    startThreadWaitingOnCondition(lock, condition, new CountDownLatch(0), signalled);
    assertFalse("The time should elapse but the latch reached zero unexpectedly", signalled.await(3000, TimeUnit.MILLISECONDS));
}

use of com.hazelcast.core.ILock in project hazelcast by hazelcast.

the class ConditionAbstractTest method testAwaitUntil_whenFail.

@Test(timeout = 60000)
public void testAwaitUntil_whenFail() throws InterruptedException {
    ILock lock = callerInstance.getLock(newName());
    ICondition condition = lock.newCondition(newName());
    lock.lock();
    assertFalse(condition.awaitUntil(currentTimeAfterGivenMillis(1000)));
}

Example 20 with ILock
