Public Member Functions

 Compressor (STREAM_READER reader, void *handle, bool gzip, int level=-1)
 Compressor (const char *input, size_t len, bool gzip, int level=-1)
bool HasOutputData ()
 More data can be read from output stream.
bool IsCompleted ()
 Output stream is completed.
bool HasBufferError ()
 Data cannot be read from input.
bool HasStreamError ()
 Data error occurred from stream.
size_t ReadOutput (char *buf, size_t len)
