@class IO::ZipArchive
|
|
|
|
Private helper class for ZipFileSystem to hold per-Zip-archive data.
|
|
Uses the zlib and the minizip lib for zip file access.
|
|
|
|
Multithreading: access to zlib archives needs to be serialized. A
|
|
ZipArchive objects contains a critical section which it will hand down
|
|
to ZipFileEntry objects.
