"pellucid" is a JAVA library for transparent access to files and ZIP/JAR
archives. All archives will be handles as directories, so it is easy to
browse into them.
Pellucid provides a convenient way of integration into existing JAVA
applications. The main idea is to drill the File class by adding the ability
of transparently handling archives to it. Doing so all the existing code
using File objects may stay the same, but now you are able to browse through
archives just as they were regular directories on the file system. From the
programmer's point of view there's no longer a difference between the regular
file system and the contents of ZIP/JAR archives.
Limitations of the current version:
- archives inside an archive are handled as regular files, i.e. "pellucid"
does not provide archive recursion yet
- write operations to entries inside an archive are not supported yet
These limitations may be resolved in a future version.
