deserialize()

const Ptr< Chunk > inet::EthernetControlFrameSerializer::deserialize ( MemoryInputStream &  stream ) const

overrideprotectedvirtual

Deserializes a chunk from a stream by reading the bytes at the current position of the stream.

The current stream position is updated according to the length of the returned chunk.

Implements inet::FieldsChunkSerializer.

{
    Ptr<EthernetControlFrameBase> controlFrame = nullptr;
    uint16_t opCode = stream.readUint16Be();
    if (opCode == ETHERNET_CONTROL_PAUSE) {
        auto pauseFrame = makeShared<EthernetPauseFrame>();
        pauseFrame->setOpCode(opCode);
        pauseFrame->setPauseTime(stream.readUint16Be());
        controlFrame = pauseFrame;
    }

serialize()

void inet::EthernetControlFrameSerializer::serialize ( MemoryOutputStream &  stream, const Ptr< const Chunk > &  chunk  ) const
