Re: [aspectj-dev] AspectJ Decompling
|
I understand you completely, this was just the
information I was looking for.
In context, I am attempting to justify a development
that effectively parses an application and attempts to
pull out join points (at this stage only 'call' type,
although I realise this is not black and white) and
rebuild the aspect.aj file. This is carried out as
part of a dissertation that is concerned with AOP.
Thank you for your time, it is most appreciated.
