Detailed Description

InflateInputStreambuf is an input stream filter, that inflates the input from the attached input stream.

Deflation/Inflation is a compression/decompression method used in gzip and zip. The zlib library is used to perform the actual inflation, this class only wraps the functionality in an input stream filter.

Constructor & Destructor Documentation

zipios::InflateInputStreambuf::InflateInputStreambuf ( streambuf *  inbuf,
int  s_pos = -1,
bool  del_inbuf = false 
)
explicit

InflateInputStreambuf constructor.

Parameters:
inbufthe streambuf to use for input.
s_posa position to reset the inbuf to before reading. Specify -1 to read from the current position.
del_inbufif true is specified inbuf will be deleted, when the InflateInputStreambuf is destructed.

Member Function Documentation

bool zipios::InflateInputStreambuf::reset ( int  stream_position = -1)

Resets the zlib stream and purges input and output buffers.

repositions the input streambuf at stream_position.

Parameters:
stream_positiona position to reset the inbuf to before reading. Specify -1 to read from the current position.
