Re: [aspectj-users] defining pointcuts in a configuration file ....

[Fabio Fagundes Silveira <ffs@xxxxxx>]

Hi Matthew,

  Yes ... I change it ...
  Let me try to be a little bit more clear ...

  Let's say that I want to trace App1 and pointcut of interest is:

  pointcut logObjectCalls() :  execution(* App1.method1(..))
                               && execution(* App1.method2(..));

  So, I run:
  [ffs@aston ~]$ java -jar TraceApp App1

  So far so good ... But now, I want to trace App2 and pointcut of
interest is: (note that it has changed...)

  pointcut logObjectCalls() :  execution(* App2.met*(..))
                               && execution(* App2.foo*(Object));

  So I run:
  [ffs@aston ~]$ java -jar TraceApp App2

  Currently, I have to change logObjectCall poincut and recompile
TraceApp. What I really would like to do is get the poincuts from a
file, so that I would not need recompile it ... Is there any way?

Thank you,
Fabio
