Thanks for the pointer -- it looks cool.
I'm not sure this quite addresses the concerns of generating
Feature implementations. As far as I'm can see, it's really
a tool that you use at compile time. We're looking at dynamically
creating implementations of interfaces which aren't necessarily
defined in the core BioJava codebase (anyone can add their own
Feature interfaces). I'm quite keen that this happens without
executing external tools, since those always seem to cause hassle.
I've actually written pretty much all those code to do this
(in process) already, for the feature-projection system.
On the other hand, some of the other uses of AspectJ look
/very/ interesting to me. In particular, pre- and post-conditions
are something which have always appealed to the paranoiac in
me :-). I'll take a proper look at this over the holidays!
Thanks again,
Thomas.
