Member Function Documentation

◆ deserialize()

const Ptr< Chunk > inet::rtp::RtpPacketSerializer::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()

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

Implements inet::FieldsChunkSerializer.
