Redefined from PassiveQueueBase. Implements PassiveQueueBase. { if (queue.empty()) return NULL; cMessage *pk = (cMessage *)queue.pop(); // statistics qlenVec.record(queue.length()); return pk; }

bool DropTailQueue::enqueue (  cMessage *  msg  )  [protected, virtual]

Redefined from PassiveQueueBase. Implements PassiveQueueBase. { if (frameCapacity && queue.length() >= frameCapacity) { EV << "Queue full, dropping packet.\n"; delete msg; dropVec.record(1); return true; } else { queue.insert(msg); qlenVec.record(queue.length()); return false; } }
