Examples with MapLoader com.hazelcast.core.MapLoader used on opensource projects

Example 1 with MapLoader

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

the class MapLoaderTest method testMapCanBeLoaded_whenLoadAllKeysThrowsExceptionFirstTime.

@Test(timeout = MINUTE)
public void testMapCanBeLoaded_whenLoadAllKeysThrowsExceptionFirstTime() throws InterruptedException {
    Config config = getConfig();
    MapLoader failingMapLoader = new FailingMapLoader();
    MapStoreConfig mapStoreConfig = new MapStoreConfig().setImplementation(failingMapLoader);
    MapConfig mapConfig = config.getMapConfig(getClass().getName()).setMapStoreConfig(mapStoreConfig);
    HazelcastInstance[] hz = createHazelcastInstanceFactory(2).newInstances(config, 2);
    IMap map = hz[0].getMap(mapConfig.getName());
    Throwable exception = null;
    try {
        map.get(generateKeyNotOwnedBy(hz[0]));
    } catch (Throwable e) {
        exception = e;
    }
    assertNotNull("Exception wasn't propagated", exception);
    map.loadAll(true);
    assertEquals(1, map.size());
}

Example 2 with MapLoader

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

the class MapLoaderTest method test1770.

// https://github.com/hazelcast/hazelcast/issues/1770
@Test
public void test1770() throws InterruptedException {
    Config config = getConfig();
    config.getManagementCenterConfig().setEnabled(true);
    config.getManagementCenterConfig().setUrl("http://127.0.0.1:8090/mancenter");
    MapConfig mapConfig = config.getMapConfig("foo");
    final AtomicBoolean loadAllCalled = new AtomicBoolean();
    MapLoader<Object, Object> mapLoader = new MapLoader<Object, Object>() {

        @Override
        public Object load(Object key) {
            return null;
        }

        @Override
        public Map<Object, Object> loadAll(Collection keys) {
            loadAllCalled.set(true);
            return new HashMap<Object, Object>();
        }

        @Override
        public Set<Object> loadAllKeys() {
            return new HashSet<Object>(Collections.singletonList(1));
        }
    };
    MapStoreConfig mapStoreConfig = new MapStoreConfig();
    mapStoreConfig.setEnabled(true);
    mapStoreConfig.setImplementation(mapLoader);
    mapConfig.setMapStoreConfig(mapStoreConfig);
    HazelcastInstance hz = createHazelcastInstance(config);
    hz.getMap(mapConfig.getName());
    assertTrueAllTheTime(new AssertTask() {

        @Override
        public void run() {
            assertFalse("LoadAll should not have been called", loadAllCalled.get());
        }
    }, 10);
