Example 26 with ListChangeEventTracker

use of org.eclipse.jface.databinding.conformance.util.ListChangeEventTracker in project eclipse.platform.ui by eclipse-platform.

the class JavaBeanObservableArrayBasedListTest method testSetBeanProperty_CorrectForNullOldAndNewValues.

@Test
public void testSetBeanProperty_CorrectForNullOldAndNewValues() {
    // The java bean spec allows the old and new values in a
    // PropertyChangeEvent to be null, which indicates that an unknown
    // change occured.
    // This test ensures that JavaBeanObservableValue fires the correct
    // value diff even if the bean implementor is lazy :-P
    Bean bean = new AnnoyingBean();
    bean.setArray(new Object[] { "old" });
    IObservableList observable = BeansObservables.observeList(new CurrentRealm(true), bean, "array");
    ListChangeEventTracker tracker = ListChangeEventTracker.observe(observable);
    bean.setArray(new Object[] { "new" });
    assertEquals(1, tracker.count);
    List list = new ArrayList();
    list.add("old");
    tracker.event.diff.applyTo(list);
    assertEquals(Collections.singletonList("new"), list);
}
