Re: [ajdt-dev] Getting annotations from AdviceElement

["Andrew Eisenberg" <andrew@xxxxxxxxxxxx>]

AspectJ ASTs do not support the resolving of bindings (see bug
https://bugs.eclipse.org/bugs/show_bug.cgi?id=146528).

So, Raffi's solution may not work (but I may be wrong).

Another possibility would be to subclass AjASTVisitor, which visits an
entire pointcut.  Currently, however, the DefaultPointcut class is
used in place of most of the standard pointcuts such as execution,
calls, etc.  So, you will have to walk the AST, look for pointcut
designators and when you find one you may have to use regular
expressions to tease out any potential annotations.

Let me know if this works or if you need any more specific help.
