Package org.jruby.util

Class JarFileResource

java.lang.Object

org.jruby.util.JarResource

org.jruby.util.JarFileResource

All Implemented Interfaces:

DummyResourceStat.FileResourceExt, FileResource

class JarFileResource
extends JarResource

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.

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 IOException

Throws:

IOException

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
