Header: Poco/Zip/ZipStream.h

ZipStreamBuf is used to decompress single files from a Zip file.

Direct Base Classes: Poco::BufferedStreamBuf

All Base Classes: Poco::BufferedStreamBuf

Member Functions: close, crcValid, readFromDevice, writeToDevice

ZipStreamBuf(
    std::istream & istr,
    const ZipLocalFileHeader & fileEntry,
    bool reposition
);

Creates the ZipStreamBuf. Set reposition to false, if you do on-the-fly decompression.

ZipStreamBuf(
    std::ostream & ostr,
    ZipLocalFileHeader & fileEntry,
    bool reposition
);

Creates the ZipStreamBuf. Set reposition to false, if you do on-the-fly compression.

Destroys the ZipStreamBuf.

void close(
Poco::UInt64 & extraDataSize
);

Informs a writing outputstream that writing is done for this stream

bool crcValid() const;

Call this method once all bytes were read from the input stream to determine if the CRC is valid

int readFromDevice(
char * buffer,
std::streamsize length
);

int writeToDevice(
const char * buffer,
std::streamsize length
);
