Hi Eugene, It would be great to have a way to reuse type patterns in AspectJ... that's something I've advocated for a while. That's how I'd improve on redundancy.
But if you are using declare parents you could use the new type in your pointcut, i.e., use this pointcut execution(* *(..)) && within(XyzType+) instead of execution(* *(..)) && within(com.xyz..*) -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Eugene Kuleshov Sent: Friday, September 29, 2006 11:04 AM To: [email protected] Subject: Re: [aspectj-users] declare parents syntax Thanks Ron, I know that. But the thing is that the same pattern is used in pointcuts to apply additional aspects to the very same classes. Hence a duplication that may lead to some unexpected typos. regards, Eugene Ron Bodkin wrote: > Hi Eugene, > > declare parents accepts a type pattern, not a pointcut.
