Examples with StoreListener org.apache.sis.storage.event.StoreListener used on opensource projects

Example 1 with StoreListener

use of org.apache.sis.storage.event.StoreListener in project geotoolkit by Geomatys.

the class WeakListenerTest method testWeakStorageListener.

/**
 * Test no memory leak in weak style listener
 */
@Test
public void testWeakStorageListener() throws DataStoreException {
    FeatureTypeBuilder ftb = new FeatureTypeBuilder();
    ftb.setName("test1");
    ftb.addAttribute(Integer.class).setName("att");
    final FeatureType type1 = ftb.build();
    ftb = new FeatureTypeBuilder();
    ftb.setName("test2");
    ftb.addAttribute(Integer.class).setName("att2");
    final FeatureType type2 = ftb.build();
    final AtomicInteger count = new AtomicInteger(0);
    final InMemoryAggregate store = new InMemoryAggregate();
    StoreListener listener = new StoreListener() {

        @Override
        public void eventOccured(StoreEvent event) {
            count.incrementAndGet();
        }
    };
    final StorageListener.Weak ref = new StorageListener.Weak(listener);
    ref.registerSource(store);
    store.add(new DefiningFeatureSet(type1, null));
    assertEquals(1, count.get());
    listener = null;
    System.gc();
    store.add(new DefiningFeatureSet(type2, null));
    // listener should have desapear now, so the event should not have been send
    assertEquals(1, count.get());
}
