Detailed Description

ChunckPacket is a packet consisting of several memory chunks.

ChunkPacket is the preferred packet type when it is getting assembled step by step. Each layer can easily add further bytes without caring about other layers at all.

Member Function Documentation

extract()

ChunkPacket vanetza::ChunkPacket::extract	(	OsiLayer	from,
		OsiLayer	to
	)

Extract a range of layers from this packet to a new one. The respective layers of this ChunkPacket are empty afterwards.

Parameters

from	start at this layer (inclusive)
to	stop at this layer (inclusive)

Returns

new packet containing layers of specified range

Definition at line 67 of file chunk_packet.cpp.

layer() [1/2]

ByteBufferConvertible & vanetza::ChunkPacket::layer

(

OsiLayer

ol

)

Access ByteBufferConvertible of specific layer

Parameters

layer

ol Access this layer's data

Returns

ByteBufferConvertible, might be empty

Definition at line 28 of file chunk_packet.cpp.

layer() [2/2]

const ByteBufferConvertible & vanetza::ChunkPacket::layer

(

OsiLayer

ol

)

const

Access ByteBufferConvertible of specific layer

Parameters

layer

merge()

ChunkPacket & vanetza::ChunkPacket::merge	(	ChunkPacket &	packet,
		OsiLayer	from,
		OsiLayer	to
	)

Merge layers from another packet

Parameters

packet	source packet (layers will be moved from there)
from	start at this layer (inclusive)
to	stop at this layer (inclusive)

Returns

reference to this packet

operator[]() [1/2]

ByteBufferConvertible & vanetza::ChunkPacket::operator[] ( OsiLayer  ol )

inline

Access ByteBufferConvertible of specific layer

Parameters

layer

ol Access this layer's data

Returns

ByteBufferConvertible, might be empty

Definition at line 41 of file chunk_packet.hpp.

operator[]() [2/2]

const ByteBufferConvertible & vanetza::ChunkPacket::operator[] ( OsiLayer  ol ) const

inline

Access ByteBufferConvertible of specific layer

Parameters

layer

ol Access this layer's data

Returns

ByteBufferConvertible, might be empty

size() [1/2]

std::size_t vanetza::ChunkPacket::size

(

)

const

Get size of whole payload

Returns

payload size in bytes

Definition at line 44 of file chunk_packet.cpp.

size() [2/2]

std::size_t vanetza::ChunkPacket::size	(	OsiLayer	from,
		OsiLayer	to
	)		const
