Member Function Documentation

◆ deserialize()

const Ptr< Chunk > inet::UdpHeaderSerializer::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.

 {
     auto udpHeader = makeShared<UdpHeader>();
     udpHeader->setSourcePort(stream.readUint16Be());
     udpHeader->setDestinationPort(stream.readUint16Be());
     udpHeader->setTotalLengthField(B(stream.readUint16Be()));
     auto crc = stream.readUint16Be();
     udpHeader->setCrc(crc);
     udpHeader->setCrcMode(crc == 0 ? CRC_DISABLED : CRC_COMPUTED);
     return udpHeader;
 }

◆ serialize()

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

overrideprotectedvirtual

Serializes a chunk into a stream by writing all bytes representing the chunk at the end of the stream.

Implements inet::FieldsChunkSerializer.

     const auto& udpHeader = staticPtrCast<const UdpHeader>(chunk);
     stream.writeUint16Be(udpHeader->getSourcePort());
     stream.writeUint16Be(udpHeader->getDestinationPort());
     stream.writeUint16Be(B(udpHeader->getTotalLengthField()).get());

     if (crcMode != CRC_DISABLED && crcMode != CRC_COMPUTED)
         throw cRuntimeError("Cannot serialize UDP header without turned off or properly computed CRC, try changing the value of crcMode parameter for Udp");
     stream.writeUint16Be(udpHeader->getCrc());
