Re: [aspectj-users] Local vars and recursion

[Matthew Webster <matthew_webster@xxxxxxxxxx>]

Uli,

There is no pointcut that matches local
variable access because there is no reliable way to identify them: their
names are only included in the class as part of the debug information.
Method parameters can be matched using args() but only based on type and
position. Fields access can be matched using get/set based on both type
and name as well as the defining class.

Hi Eric:

"...But this really defeats the purpose of using AOP..."
Is correct apply AOP to debugging areas to advice local vars? I'd like
to know a little more about this.

About the last question, I mean: If args pcd matches method arguments and
these arguments are local vars implicitly, Can I identfy join points (through
the method) for that local vars using the same or similar refactoring?

Thanks a lot and I apologize for any inconvenient with grammar.
 
Uli.

Hi.
 
Well, you would have to
use a stack in that case, in order to emulate the runtime stack. But this
really defeats the purpose of using AOP in the first place I would say.
Regarding your last question: I don’t understand what you mean.

 Hi,

AspecJ doesn't support local vars pointcuts, instead a way to do it is
refactoring local vars to fields. What happens with recursive programs
wich contain local vars? Not always refactoring works. Any suggestion?

Also, if args pcd matches local vars, how can I apply a pointcut when they
are setting or getting?

Cheers
Uli.
