[Jode-users] In-memory classes?

[Howard L. S. <hl...@gm...>]

I make use of Javassist to create classes in-memory.  I was thinking
it would be useful and informative to plug JODE into my pipeline, so
that I could de-compile the dynamically generated bytecode.

Couldn't see how to do this with JODE.  It seems organized around the
bytecodes sitting in a file. Is there a way to easily support
decompling a Class object already in memory?  Alternately, I can get
the generated bytecode (into a byte[] array) and would like to
decompile that.

With the latest CVS version or 1.90-pre releases you can write your own
classpath location, which can load classes from any virtual location.

As an example, see ZipLocation, which loads classes from an in memory
zip file.  All you need is to override the getFile() method to return an
ByteArrayInputStream().  Then you can create a new ClassPath with your
location and decompile classes from this classpath.
