Member Function Documentation

void QueueBase::initialize (  )  [protected, virtual]

Reimplemented from AbstractQueue.

Reimplemented in IP, and IPv6.

Referenced by IPv6::initialize(), and IP::initialize().

00023 {
00024     AbstractQueue::initialize();
00025     delay = par("procDelay");
00026 }

void QueueBase::arrival ( cPacket *  msg  )  [protected, virtual]

Functions to (re)define behaviour Called when a message arrives at the module. The method should either enqueue this message (usual behaviour), or discard it. It may also wrap the it into another message, and insert that one in the queue.

Most straightforward implementation: queue.insert(msg);

Implements AbstractQueue.

00029 {
00030     queue.insert(msg);
00031 }

cPacket * QueueBase::arrivalWhenIdle ( cPacket *  msg  )  [protected, virtual]

Called when a message arrives at the module when the queue is empty. The message doesn't need to be enqueued in this case, it can start service immmediately. This method may:

  1. simply return the the same pointer (usual behaviour), or
  2. discard the message and return NULL pointer (the effect being this message being ignored)
  3. or modify the message, wrap in into another message etc, and return the (new) message's pointer.

Most straightforward implementation: return msg;

Implements AbstractQueue.

00034 {
00035     return msg;
00036 }

simtime_t QueueBase::startService ( cPacket *  msg  )  [protected, virtual]

Called when a message starts service, and should return the service time.

Example implementation: return 1.0;

Implements AbstractQueue.

00039 {
00040     return delay;
00041 }
