Example 3 with Event

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

the class EventBusShould method store_multiple_messages_passing_filters.

/**
 * Ensures that events are stored when all of them pass the filters.
 *
 * <p> To filter the {@link EBTaskAdded} events the {@linkplain EventBus} has a custom filter.
 * The {@link TaskCreatedFilter} filters out {@link EBTaskAdded} events with
 * {@link Task#getDone()} set to {@code true}.

    assertFalse(second.isDispatchCalled());
}

Example 5 with Event

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

the class EventBusShould method store_only_events_passing_filters.

/**
