    23   * <p>A multicaster that implements this interface allows for consumable events.
    24   * This means that the event dispatch is stopped as soon as an event is consumed.

    26   * <p>An event is consumed if a listener's event method returns {@code true}. If it
    27   * returns nothing, {@code null} or {@code undefined} or {@code false} the event
    28   * will further be dispatched.
