RE: [Jython-dev] invoking __getattr__()/__setattr__() on java objects

[brian z. <bz...@zi...>]

Ype,

I'm on board with the custom wrapping though I have a different suggestion.
In the past I made the static method Py.java2py(Object) delegate to a custom
handler (the default being the current if/else statements in Py.java2py) to
decide how to wrap a Java instance.  I controlled which handler by checking
an option in the jython registry.  I don't have the code any more but I can
code it up again and submit a patch if you or anyone else is interested in
seeing my idea.
