deserialize()

const Ptr< Chunk > inet::Ieee8022LlcHeaderSerializer::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.

serialize()

void inet::Ieee8022LlcHeaderSerializer::serialize ( MemoryOutputStream &  stream, const Ptr< const Chunk > &  chunk  ) const

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

Implements inet::FieldsChunkSerializer.
