Constructors
InflatingIOS
InflatingIOS(
std::ostream & ostr,
InflatingStreamBuf::StreamType type = InflatingStreamBuf::STREAM_ZLIB
);
Creates an InflatingIOS for expanding the compressed data passed through and forwarding it to the given output stream.
InflatingIOS
InflatingIOS(
std::ostream & ostr,
int windowBits
);
Creates an InflatingIOS for expanding the compressed data passed through and forwarding it to the given output stream.
Please refer to the zlib documentation of inflateInit2() for a description of the windowBits parameter.
InflatingIOS
InflatingIOS(
std::istream & istr,
InflatingStreamBuf::StreamType type = InflatingStreamBuf::STREAM_ZLIB
);
Creates an InflatingIOS for expanding the compressed data read from the given input stream.
InflatingIOS
InflatingIOS(
std::istream & istr,
int windowBits
);
