Examples with Event io.spine.core.Event used on opensource projects

Example 6 with Event

use of io.spine.core.Event in project core-java by SpineEventEngine.

the class EventBusShould method not_store_an_invalid_event.

@Test
public void not_store_an_invalid_event() {
    final Command command = command(invalidArchiveProject());
    eventBus.register(new EBProjectArchivedSubscriber());
    commandBus.post(command, StreamObservers.<Ack>noOpObserver());
    final List<Event> events = readEvents(eventBus);
    assertSize(0, events);
}

Example 7 with Event

use of io.spine.core.Event in project core-java by SpineEventEngine.

the class EventBusShould method store_filters_regarding_possible_concurrent_modifications.

/**
 * Tests the concurrent access to the {@linkplain io.spine.server.bus.BusFilter bus filters}.
 *
 * <p>The {@linkplain io.spine.server.bus.FilterChain filter chain} is a queue of the filters
 * which are sequentially applied to the posted message. The first {@code Bus.post()} call
 * invokes the filters lazy initialization. In the concurrent environment (which is natural for
 * a {@link io.spine.server.bus.Bus Bus}), the initialization may be performed multiple times.
 * Thus, some unexpected issues may appear when accessing the non-synchronously initialized
 * filter chain.
 *
 * <p>To make sure that the chain works fine (i.e. produces no exceptions), we invoke the
 * initialization multiple times from several threads.
