> By default, incoming (local) queue will be reset in every superstep. It means
> that unconsumed messages will be lost. If this is persistent queue,
> unconsumed messages will be persisted in incoming queue.
> {code}
> public final void clearOutgoingQueues() {
> if (localQueue != null) {
> localQueue.close();
> }
> localQueue = localQueueForNextIteration.getMessageQueue();
> localQueue.prepareRead();
> localQueueForNextIteration = getSynchronizedReceiverQueue();
> notifyInit();
> }
> {code}
> Simply we can add unconsumed messages to localQueueForNextIteration before
> switching local queue.
