| typedef std::vector<DtMessage*> makVrv::DtMessageStream::MessageList |
| typedef std::vector<Byte> makVrv::DtMessageStream::ByteBuffer |
| makVrv::DtMessageStream::DtMessageStream | ( | size_t | initialReserve = 0xFFF | ) |
Create a stream with an initial reserve.
| makVrv::DtMessageStream::~DtMessageStream | ( | ) |
DTOR.
| void makVrv::DtMessageStream::clearStream | ( | ) |
Clears all the data in the stream.
| void makVrv::DtMessageStream::writeMessageToStream | ( | DtMessage * | message | ) |
Methods used to encode messages onto a stream.
Add a message to the stream.
| void makVrv::DtMessageStream::writeMessagesToStream | ( | MessageList & | messages | ) |
Add messages to stream.
| Byte* makVrv::DtMessageStream::streamData | ( | ) | const |
Methods for getting the binary data.
Get a pointer to the stream data (binary).
| size_t makVrv::DtMessageStream::streamDataSize | ( | ) | const |
Get the size of the stream data (binary).
| void makVrv::DtMessageStream::addDataToStream | ( | char * | data, |
| size_t | size | ||
| ) |
Methods for added raw data to a stream.
Add Raw data.
| Byte* makVrv::DtMessageStream::addSpaceToStream | ( | size_t | size | ) |
Add Empty space to stream and return pointer to data (for writing directly into.
| void makVrv::DtMessageStream::trimEnd | ( | size_t | n | ) |
Removes the last 'n' bytes from the end of the stream.
| int makVrv::DtMessageStream::readMessagesFromStream | ( | MessageList & | messages | ) |
Read messages from a stream. The stream data will shrink after each call. Returns the number of messages read. If a corrupted message is detected, this will return -1.
