Header: Poco/InflatingStream.h
Description
This stream decompresses all data passing through it using zlib's inflate algorithm. Example:
std::ifstream istr("data.gz", std::ios::binary);
InflatingInputStream inflater(istr, InflatingStreamBuf::STREAM_GZIP);
std::string data;
inflater >> data;
The underlying input stream can contain more than one gzip/deflate stream. After a gzip/deflate stream has been processed, reset() can be called to inflate the next stream.

Constructors
InflatingInputStream
InflatingInputStream(
std::istream & istr,
InflatingStreamBuf::StreamType type = InflatingStreamBuf::STREAM_ZLIB
);
Creates an InflatingInputStream for expanding the compressed data read from the given input stream.
InflatingInputStream
InflatingInputStream(
std::istream & istr,
int windowBits
);
Creates an InflatingInputStream for expanding the compressed data read from the given input stream.
Please refer to the zlib documentation of inflateInit2() for a description of the windowBits parameter.
Destructor
~InflatingInputStream
Destroys the InflatingInputStream.
Member Functions
reset
void reset();
Resets the zlib machinery so that another zlib stream can be read from the same underlying input stream.
