Class JarFileResource

org.jruby.util.AbstractFileResource

org.jruby.util.JarResource

org.jruby.util.JarFileResource

All Implemented Interfaces:

FileResource

class JarFileResource

Represents a file in a jar.

Note: while directories can be contained within a jar, they're still represented by JarDirectoryResource, since Ruby expects a directory to exist as long as any files in that directory do, or Dir.glob would break.
