Member Summary

Member Functions: createHeader, getCentralDirectoryOffset, getCentralDirectorySize, getDiskNumber, getFirstDiskForDirectoryHeader, getHeaderOffset, getNumberOfEntries, getRequiredVersion, getTotalNumberOfEntries, getVersionMadeBy, setCentralDirectoryOffset, setCentralDirectorySize, setHeaderOffset, setNumberOfEntries, setTotalNumberOfDisks, setTotalNumberOfEntries

Constructors

ZipArchiveInfo64

ZipArchiveInfo64();

Default constructor, everything set to zero or empty

ZipArchiveInfo64

ZipArchiveInfo64(
    std::istream & in,
    bool assumeHeaderRead
);

Creates the ZipArchiveInfo64 by parsing the input stream. If assumeHeaderRead is true we assume that the first 4 bytes were already read outside.

Destructor

~ZipArchiveInfo64

~ZipArchiveInfo64();

Destroys the ZipArchiveInfo64.
