Example 1 with Registration

use of com.vaadin.flow.shared.Registration in project flow by vaadin.

    final BootstrapContext context = bootstrapHandler.createAndInitUI(TestUI.class, createVaadinRequest(), response, session);
    Assert.assertEquals("Event UI didn't match initialized UI instance.", context.getUI(), uiReference.get());
    // unregister listener
    registration.remove();
    AtomicReference<UI> secondListenerReference = new AtomicReference<>();
    service.addUIInitListener(event -> Assert.assertTrue("Atomic reference did not contain previous UI.", uiReference.compareAndSet(context.getUI(), event.getUI())));
    service.addUIInitListener(event -> Assert.assertTrue("Atomic reference was not empty.", secondListenerReference.compareAndSet(null, event.getUI())));
    final BootstrapContext secondInit = bootstrapHandler.createAndInitUI(TestUI.class, createVaadinRequest(), response, session);
    Assert.assertEquals("Event UI didn't match initialized UI instance.", secondInit.getUI(), uiReference.get());

}

    Assert.assertFalse("Detach listener was triggered even though handler was removed.", triggered.get());
}

Example 4 with Registration

use of com.vaadin.flow.shared.Registration in project flow by vaadin.

    PropertyChangeListener listener = ev -> {
        Assert.fail();
    };
    Registration registration = map.addPropertyChangeListener("foo", listener);
    registration.remove();
    // listener is not called. Otherwise its assertion fails.
    map.setProperty("foo", "bar", true);
