Re: [aspectj-users] Modifying only least-derived class

[Joel Shellman <joel@xxxxxxxxxxxx>]

Thanks for the response. It looks like that way isn't going to work for me
anyway.

As I mentioned, I'm trying to write aspects for an open source JDO
implementation. The problem is that it seems there is very little
flexibility regarding where you can introduce methods/fields (inter-type
declarations). The reference says:

Modifiers ReturnType OnType . Id(Formals) { Body }

Which means that you have to specify the OnType explicitly--you can't even
do a TypeMapping for it.

My next step will be to try to see about selective application of the
enhancement aspect at class loading time. I'm probably going to need that
anyway. I saw something in the FAQ about there being an example either
already out or forthcoming, so I'll try to take a look at that.
