Example 1 with EntryUpdatedListener

use of com.hazelcast.map.listener.EntryUpdatedListener in project hazelcast by hazelcast.

the class QueryCacheCoalescingTest method testCoalescingModeWorks.

@Test
public void testCoalescingModeWorks() {
    String mapName = randomString();
    String cacheName = randomString();
    Config config = getConfig(mapName, cacheName);
    HazelcastInstance node = createHazelcastInstance(config);
    IMap<Integer, Integer> map = getMap(node, mapName);
    final CountDownLatch updateEventCount = new CountDownLatch(1);
    final QueryCache<Integer, Integer> cache = map.getQueryCache(cacheName, TRUE_PREDICATE, true);
    cache.addEntryListener(new EntryUpdatedListener() {

        @Override
        public void entryUpdated(EntryEvent event) {
            updateEventCount.countDown();
        }
    }, false);
    for (int i = 0; i < 100; i++) {
        map.put(i, i);
    }
    // update same key to control whether coalescing kicks in.
    for (int i = 0; i < 500; i++) {
        map.put(0, i);
    }
    assertTrueEventually(new AssertTask() {

        @Override
