Re: [aspectj-users] aspectj joinpoint *for* Annotation ?

[Andy Clement <andrew.clement@xxxxxxxxx>]

Not sure what kind of matching you want to do (kind of joinpoint, kind
of annotation value). If I understand what you mean, there is already
some support for this, see the "annotation value matching" section in
(this is execution joinpoint, enum annotation value):

http://www.eclipse.org/aspectj/doc/released/README-160.html

optimized binding of values is in:
http://www.eclipse.org/aspectj/doc/released/README-161.html

cheers,
Andy
