Examples with ObserverCreatedEvent arez.spy.ObserverCreatedEvent used on opensource projects

Example 1 with ObserverCreatedEvent

use of arez.spy.ObserverCreatedEvent in project arez by arez.

the class SpyEventProcessorTest method maintainNesting.

@Test
public void maintainNesting() throws Throwable {
    final TestSpyEventProcessor processor = new TestSpyEventProcessor();
    final ObserverCreatedEvent event = new ObserverCreatedEvent(new NullObserverInfo());
    final AtomicInteger handleCallCount = new AtomicInteger();
    final BiConsumer<SpyUtil.NestingDelta, ObserverCreatedEvent> handler = (delta, e) -> {
        handleCallCount.incrementAndGet();
        assertEquals(delta, SpyUtil.NestingDelta.NONE);
        assertEquals(e, event);
    };
    processor.on(ObserverCreatedEvent.class, handler);
    assertEquals(processor.getNestingDelta(event), SpyUtil.NestingDelta.NONE);
    assertEquals(handleCallCount.get(), 0);
    assertEquals(processor.getNestingLevel(), 0);
    assertEquals(processor._handleUnhandledEventCallCount, 0);
    processor.onSpyEvent(event);
    assertEquals(handleCallCount.get(), 1);
    assertEquals(processor.getNestingLevel(), 0);
    assertEquals(processor._handleUnhandledEventCallCount, 0);
}

Example 2 with ObserverCreatedEvent

use of arez.spy.ObserverCreatedEvent in project arez by arez.

the class ArezContext method createObserver.

/**
 * Create an observer with specified parameters.
 *
 * @param component    the component containing observer if any. Should be null if {@link Arez#areNativeComponentsEnabled()} returns false.
 * @param name         the name of the observer.
 * @param mutation     true if the reaction may modify state, false otherwise.
 * @param reaction     the reaction defining observer.
 * @param highPriority true if the observer is a high priority observer.
 * @return the new Observer.
