Examples with MembershipAwareService com.hazelcast.spi.MembershipAwareService used on opensource projects

Example 1 with MembershipAwareService

use of com.hazelcast.spi.MembershipAwareService in project hazelcast by hazelcast.

the class QuorumTest method testQuorumIgnoresMemberAttributeEvents.

@Test
public void testQuorumIgnoresMemberAttributeEvents() {
    final RecordingQuorumFunction function = new RecordingQuorumFunction();
    QuorumConfig quorumConfig = new QuorumConfig().setName(randomString()).setEnabled(true).setQuorumFunctionImplementation(function);
    Config config = new Config().addQuorumConfig(quorumConfig);
    HazelcastInstance hazelcastInstance = createHazelcastInstance(config);
    NodeEngineImpl nodeEngine = getNodeEngineImpl(hazelcastInstance);
    MembershipAwareService service = nodeEngine.getService(QuorumServiceImpl.SERVICE_NAME);
    assertTrueEventually(new AssertTask() {

        @Override
        public void run() throws Exception {
            assertTrue(function.wasCalled);
        }
    });
    function.wasCalled = false;
    MemberAttributeServiceEvent event = mock(MemberAttributeServiceEvent.class);
    service.memberAttributeChanged(event);
    assertFalse(function.wasCalled);
}

Example 2 with MembershipAwareService

    final MemberAttributeServiceEvent event = new MemberAttributeServiceEvent(this, member, operationType, key, value);
    MemberAttributeEvent attributeEvent = new MemberAttributeEvent(this, member, operationType, key, value);

    if (membershipAwareServices != null && !membershipAwareServices.isEmpty()) {
        for (final MembershipAwareService service : membershipAwareServices) {
            // service events should not block each other
            nodeEngine.getExecutionService().execute(ExecutionService.SYSTEM_EXECUTOR, new Runnable() {

                public void run() {
                    service.memberAttributeChanged(event);

    for (EventRegistration reg : registrations) {
        eventService.publishEvent(SERVICE_NAME, reg, attributeEvent, reg.getId().hashCode());
    }
}
