Member Function Documentation

◆ finish()

void inet::queueing::PcapFilePacketProducer::finish ( )

overrideprotectedvirtual

 {
     if (pcapReader.isOpen())
         pcapReader.closePcap();
 }

◆ handleCanPushPacketChanged()

void inet::queueing::PcapFilePacketProducer::handleCanPushPacketChanged ( cGate * gate )

overridevirtual

Notifies about a change in the possibility of pushing some packet into the passive packet sink at the given gate.

This method is called, for example, when a new packet can be inserted into a queue. It allows the source to push a new packet into the queue.

The gate parameter must be a valid gate of this module.

Implements inet::queueing::IActivePacketSource.

 {
     Enter_Method("handleCanPushPacketChanged");
     if (gate == outputGate)
         schedulePacket();
 }

◆ handleMessage()

◆ handlePushPacketProcessed()

virtual void inet::queueing::PcapFilePacketProducer::handlePushPacketProcessed	(	Packet *	packet,
		cGate *	gate,
		bool	successful
	)

inlineoverridevirtual

Notifies about the completion of the packet processing for a packet that was pushed earlier independently whether the packet is passed or streamed.

This method is called, for example, when a previously pushed packet is failed to be processed successfully. It allows the source to retry the operation.

The gate parameter must be a valid gate of this module. The packet must not be nullptr.

Implements inet::queueing::IActivePacketSource.
