Class JarDirectoryResource

java.lang.Object

org.jruby.util.JarResource

org.jruby.util.JarDirectoryResource

All Implemented Interfaces:

DummyResourceStat.FileResourceExt, FileResource

class JarDirectoryResource
extends JarResource

Represents a directory in a jar.

Jars do not necessarily have to contain entries for a directory. However, from ruby's point of view, if a jar contains entry /foo/bar, it already contains /foo directory. This resource permits just that.

openInputStream

public InputStream openInputStream()
                            throws IOException

Description copied from interface: FileResource

Opens a new input stream to read the contents of a resource and returns it. Note that implementations may be allocating native memory for the stream, so callers need to close this when they are done with it. users of this method should follow the pattern: close the stream where you open it.

Returns:

InputStream

Throws:

IOException

openChannel

public Channel openChannel(int flags,
 int perm)
                    throws ResourceException

Throws:

ResourceException

unwrap

public <T> T unwrap(Class<T> type)

Description copied from interface: FileResource

Unwrap the resource backend (replacement for FileResource.hackyGetJRubyFile()).

Returns:

backend if supported
