## Member Functions

### handleZipEntry

virtual bool handleZipEntry(
std::istream & zipStream,
const ZipLocalFileHeader & hdr
) = 0;

Handles parsing of the data of a single Zip Entry. zipStream is guaranteed to be at the very first data byte. Note that a callback class SHOULD consume all data inside a zip file, ie. after processing the next 4 bytes point the next ZipLocalFileHeader or the ZipDirectory. If it fails to do so, it must return false, otherwise true.
