Constructors
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.
