Examples of com.hazelcast.core.ICondition

com.hazelcast.core.ICondition
Distributed implementation of {@link Condition}. An ICondition instance is created using {@link ILock#newCondition(String)}
```
 HazelcastInstance instance = ...; ILock lock = instance.getLock("lock"); ICondition cond = lock.newCondition("condition"); ... 
```
@see Condition @see ILock

        config.setProperty(GroupProperties.PROP_OPERATION_CALL_TIMEOUT_MILLIS, "5000");


        HazelcastInstance instance = createHazelcastInstance(config);


        final ILock lock = instance.getLock(randomString());
        final ICondition condition0 = lock.newCondition(randomString());


        final CountDownLatch latch = new CountDownLatch(1);


        Thread thread = new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    lock.lock();
                    condition0.await();
                } catch (InterruptedException e) {
                    latch.countDown();
                }
            }
