Member Function Documentation
[explicit protected] Encoder::Encoder(KCodecs::Codec::NewlineType newline = Codec::NewlineLF)
Protected constructor. Use KCodecs::Codec::makeEncoder if you want one.
newline whether make new lines using CRLF, or LF (default is LF).
[pure virtual] bool Encoder::encode(const char *&scursor, const char *const send, char *&dcursor, const char *const dend)
Encodes a chunk of data, maintaining state information between calls. See KCodecs::Codec for calling conventions.
scursor is a pointer to the start of the input buffer.
send is a pointer to the end of the input buffer.
dcursor is a pointer to the start of the output buffer.
dend is a pointer to the end of the output buffer.
Returns true on success
[pure virtual] bool Encoder::finish(char *&dcursor, const char *const dend)
Call this method to finalize the output stream. Writes all remaining data and resets the encoder. See KCodecs::Codec for calling conventions.
dcursor is a pointer to the start of the output buffer.
dend is a pointer to the end of the output buffer.
Returns true on success.
[protected] bool Encoder::flushOutputBuffer(char *&dcursor, const char *const dend)
Writes characters from the output buffer to the output stream. Implementations of encode and finish should call this at the very beginning and for each iteration of the while loop.
dcursor is a pointer to the start of the output buffer.
dend is a pointer to the end of the output buffer.
Returns true if all chars could be written, false otherwise
[protected] bool Encoder::write(char ch, char *&dcursor, const char *const dend)
Writes character ch to the output stream or the output buffer, depending on whether or not the output stream has space left.
ch is the character to write.
dcursor is a pointer to the start of the output buffer.
dend is a pointer to the end of the output buffer.
Returns true if written to the output stream; else false if buffered.
[protected] bool Encoder::writeCRLF(char *&dcursor, const char *const dend)
Convenience function. Outputs LF or CRLF, based on the state of mWithCRLF.
dcursor is a pointer to the start of the output buffer.
dend is a pointer to the end of the output buffer.
Returns true on success
