Examples of com.hazelcast.core.MultiExecutionCallback

com.hazelcast.core.MultiExecutionCallback
MultiExecutionCallback allows to get notified when an execution is completed on each member which task is submitted to. After all executions are completed on all submitted members, {@link #onComplete(java.util.Map)} method is called with map of all results. @see IExecutorService @see ExecutionCallback

        final int k = simpleTestNodeCount;
        TestHazelcastInstanceFactory factory = createHazelcastInstanceFactory(k);
        final HazelcastInstance[] instances = factory.newInstances(new Config());
        final AtomicInteger count = new AtomicInteger(0);
        final CountDownLatch latch = new CountDownLatch(k);
        final MultiExecutionCallback callback = new MultiExecutionCallback() {
            public void onResponse(Member member, Object value) {
                count.incrementAndGet();
            }


            public void onComplete(Map<Member, Object> values) {
