Public Methods

void PacketWriter ()

Creates a packet writer with an empty packet vector.

Defined at line 12 of file ../../src/connectivity/network/mdns/service/encoding/packet_writer.cc

void PacketWriter (std::vector<uint8_t> packet)

Creates a packet writer that writes to the supplied vector. The intended

pattern here is that a buffer is moved into the writer using a call like

|PacketWriter(std::move(my_buffer))| and moved back out when writing is

complete using |GetPacket|. Call |position| before calling |GetPacket| to

retrieve the size of the written data. In this way, a fixed-length buffer

may be used repeatedly without the allocations implied by creating a new

buffer or resizing an existing one. Note that the buffer *will* be resized

if it's too small to accommodate the written packet.

void ~PacketWriter ()

Defined at line 16 of file ../../src/connectivity/network/mdns/service/encoding/packet_writer.cc

std::vector<uint8_t> GetResizedPacket ()

Gets the packet vector and resets this |PacketWriter| after resizing the

vector to |position()| bytes. If the caller is using the default

constructor, allowing the writer to create its own buffer, this is a

good way to get that buffer out of the writer once writing is complete.

To reuse a fixed-size buffer, use the constructor that takes a packet

parameter, |position| to get the written size and |GetPacket| to take back

the buffer.

std::vector<uint8_t> GetPacket ()

Gets the unresized packet vector and resets this |PacketWriter|. To

get the size of the written packet, call |position()| before calling this

method.

void PutBytes (size_t count, const void * source)

Puts |count| bytes from |source| into the packet.

size_t position ()

Gets the current position.

void SetPosition (size_t position)

Sets the current position.

void CreateBookmark (const std::string & name)

Creates a bookmark for the current position.

Defined at line 47 of file ../../src/connectivity/network/mdns/service/encoding/packet_writer.cc

size_t GetBookmarkPosition (const std::string & name)

Gets the position for a bookmark (established by calling |CreateBookmark|).

Returns |npos| if the bookmark isn't found.
