A class responsible for compressing and decompressing data for the MCCP server option.
In the mccp::codec class, control flow is managed by interleaving certain tags within the data stream.
In particular, the begin_compression tag will cause all data from the next token to be sent in a compressed format. The end_compression tag ends this process.
Additionally, sending a begin_decompression tag will cause all data from the next token to be received in a compressed format, and will be returned in a decompressed format. This can be cancelled by either sending an end_decompression tag, or if the compressed stream is marked as finished.
Actual compression and decompression is handled by the compressor and decompressor objects passed in during construction.
| telnetpp::u8stream telnetpp::options::mccp::codec::receive | ( | telnetpp::u8 | byte | ) |
Receive a byte from the lower layer, decompress it if necessary, and return the result as a stream of bytes.
| std::vector< telnetpp::stream_token > telnetpp::options::mccp::codec::send | ( | std::vector< telnetpp::stream_token > const & | tokens | ) |
In a manner consistent with the rest of the telnetpp library, interprets the stream and returns a similar stream that is either compressed or uncompressed, as appropriate, that can be sent to the next lower layer.
