Member Function Documentation

◆ getNumPacketDuplicates()

int inet::StreamSplitter::getNumPacketDuplicates ( Packet * packet )

overrideprotectedvirtual

Returns the number of duplicates to be generated.

Implements inet::queueing::IPacketDuplicator.

 {
     auto streamReq = packet->findTag<StreamReq>();
     auto streamName = streamReq != nullptr ? streamReq->getStreamName() : "";
     if (mapping->containsKey(streamName)) {
         cValueArray *outputStreams = check_and_cast<cValueArray *>(mapping->get(streamName).objectValue());
         return outputStreams->size() - 1;
     }
     else
         return 0;
 }

◆ getRegistrationForwardingGate()

cGate * inet::StreamSplitter::getRegistrationForwardingGate ( cGate * gate )

overrideprotectedvirtual

Reimplemented from inet::TransparentProtocolRegistrationListener.

 {
     if (gate == outputGate)
         return inputGate;
     else if (gate == inputGate)
         return outputGate;
     else
         throw cRuntimeError("Unknown gate");
 }

◆ handleParameterChange()

void inet::StreamSplitter::handleParameterChange ( const char * name )

overrideprotectedvirtual

 {
     if (name != nullptr) {
         if (!strcmp(name, "mapping"))
             mapping = check_and_cast<cValueMap *>(par("mapping").objectValue());
    }
 }

◆ initialize()

void inet::StreamSplitter::initialize ( int stage )

overrideprotectedvirtual

Reimplemented from inet::queueing::PacketDuplicatorBase.

 {
     PacketDuplicatorBase::initialize(stage);
     if (stage == INITSTAGE_LOCAL)
         mapping = check_and_cast<cValueMap *>(par("mapping").objectValue());
 }

◆ pushPacket()

void inet::StreamSplitter::pushPacket	(	Packet *	packet,
		cGate *	gate
	)

overrideprotectedvirtual

Pushes the packet into the packet sink at the given gate.

This operation pushes the packet as a whole. The onwership of the packet is transferred to the sink.

This method is called, for example, when a packet source module pushes a packet into a queue module.

The sink must not be full at the gate. The packet must not be nullptr. The gate must be a valid gate of this module and it must support pushing and passing packets.

Reimplemented from inet::queueing::PacketDuplicatorBase.

 {
     Enter_Method("pushPacket");
     take(packet);
     auto streamReq = packet->findTag<StreamReq>();
     if (streamReq != nullptr) {
         auto streamName = streamReq->getStreamName();
         if (mapping->containsKey(streamName)) {
             cValueArray *outputStreams = check_and_cast<cValueArray *>(mapping->get(streamName).objectValue());
             for (int i = 0; i < outputStreams->size(); i++) {
                 const char *splitStreamName = outputStreams->get(i).stringValue();
                 auto duplicate = packet->dup();
                 duplicate->addTagIfAbsent<StreamReq>()->setStreamName(splitStreamName);
                 pushOrSendPacket(duplicate, outputGate, consumer);
             }
             handlePacketProcessed(packet);
             delete packet;
         }
         else {
             handlePacketProcessed(packet);
             pushOrSendPacket(packet, outputGate, consumer);
         }
     }
     else {
         handlePacketProcessed(packet);
         pushOrSendPacket(packet, outputGate, consumer);
