Example 27 with LifecycleListener

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

the class NodeQueryCacheContext method flushPublishersOnNodeShutdown.

/**
     * This is a best effort approach; there is no guarantee that events in publishers internal buffers will be fired,
     * {@link com.hazelcast.spi.EventService} can drop them.
     */
private void flushPublishersOnNodeShutdown() {
    Node node = ((NodeEngineImpl) this.nodeEngine).getNode();
    LifecycleServiceImpl lifecycleService = node.hazelcastInstance.getLifecycleService();
    lifecycleService.addLifecycleListener(new LifecycleListener() {

        @Override
        public void stateChanged(LifecycleEvent event) {
            if (SHUTTING_DOWN == event.getState()) {
                publisherContext.flush();
            }
        }
    });
