Implementation

      if (event is AsynchronizedEvent && event.isAsynchronized()) {
        await container.listener(event);
      } else {
        container.listener(event);
      }
      if (container.limit > 0) {
        container.limit--;
      }
      if (container.limit == 0) {

      }
      if (event is CancelledEvent && event.isCancelled()) {
        break;
      }
