Detailed Description

Partial implementation of the zip file format according to http://www.pkware.com/business_and_developers/developer/popups/appnote.txt http://www.pkware.com/documents/casestudies/APPNOTE.TXT 99% of zip files on my system can be read with this class.

Exceptions are files that are (at least)

• files generated by writing to stdout
• files using other compression as deflated
• encrypted files

[virtual]

Get the next substream.

This function should return a stream representing the next substream that can be read from the input stream, or 0 if there are no more substreams.

For example, if the input stream were a tar archive, it would return a stream representing the next file or directory in the archive.

It should also load the substream (the same one that was returned) into entrystream, and set entryinfo to an EntryInfo giving information about the substream.

If there may be more substreams, but an error occurred, 0 should be returned, the status should be set to Error and an error message should be set.

Returns:

the next substream, or 0 if there are no more substreams or an error occurred

Implements Strigi::SubStreamProvider.
