Re: [aspectj-users] Pointcut for "where any parameters are annotated by"

[Andy Clement <andrew.clement@xxxxxxxxx>]

Hi Matthew,

This is discussed in here:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=233718

but there are still issues around agreeing a syntax (and a reasonable
implementation).

At the moment the best you can do is what you have, support annotation
of argument 'n' by having variants for each.

Maybe add your proposed syntax to that bugzilla as a suggestion, I
don't think we have something like that.

cheers,
Andy
