IPvXAddress UDPBasicApp::chooseDestAddr (   )  [protected, virtual]

{ int k = intrand(destAddresses.size()); return destAddresses[k]; }

cMessage * UDPBasicApp::createPacket (   )  [protected, virtual]

Reimplemented in UDPEchoApp. { char msgName[32]; sprintf(msgName,"UDPBasicAppData-%d", counter++); cMessage *payload = new cMessage(msgName); payload->setByteLength(msgByteLength); return payload; }

void UDPBasicApp::handleMessage (  cMessage *  msg  )  [protected, virtual]

{ if (msg->isSelfMessage()) { // send, then reschedule next sending sendPacket(); scheduleAt(simTime()+(double)par("message_freq"), msg); } else { // process incoming packet processPacket(msg); } if (ev.isGUI()) { char buf[40]; sprintf(buf, "rcvd: %d pks\nsent: %d pks", numReceived, numSent); displayString().setTagArg("t",0,buf); } }

void UDPBasicApp::initialize (  int  stage  )  [protected, virtual]

Reimplemented in UDPEchoApp. { // because of IPAddressResolver, we need to wait until interfaces are registered, // address auto-assignment takes place etc. if (stage!=3) return; counter = 0; numSent = 0; numReceived = 0; WATCH(numSent); WATCH(numReceived); localPort = par("local_port"); destPort = par("dest_port"); msgByteLength = par("message_length").longValue() / 8; // FIXME param should be in bytes instead const char *destAddrs = par("dest_addresses"); cStringTokenizer tokenizer(destAddrs); const char *token; while ((token = tokenizer.nextToken())!=NULL) destAddresses.push_back(IPAddressResolver().resolve(token)); if (destAddresses.empty()) return; bindToPort(localPort); cMessage *timer = new cMessage("sendTimer"); scheduleAt((double)par("message_freq"), timer); }

virtual int UDPBasicApp::numInitStages (   )  const [inline, protected, virtual]

{return 4;}

void UDPBasicApp::processPacket (  cMessage *  msg  )  [protected, virtual]

Reimplemented in UDPEchoApp. { EV << "Received packet: "; printPacket(msg); delete msg; numReceived++; }

void UDPBasicApp::sendPacket (   )  [protected, virtual]

{ cMessage *payload = createPacket(); IPvXAddress destAddr = chooseDestAddr(); sendToUDP(payload, localPort, destAddr, destPort); numSent++; }
