Detailed Documentation

The base class for InflatingOutputStream and InflatingInputStream.

This class is needed to ensure the correct initialization order of the stream buffer and base classes.

Construction

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(
    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(
    std::istream& istr,
    InflatingStreamBuf::StreamType type = InflatingStreamBuf::STREAM_ZLIB
    )

Creates an InflatingIOS for expanding the compressed data read from the given input stream.

InflatingIOS(
    std::istream& istr,
    int windowBits
    )

Creates an InflatingIOS 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.

Methods

InflatingStreamBuf*
rdbuf()

Returns a pointer to the underlying stream buffer.
