Re: [aspectj-users] Use aspectj to inject control flow

[Ramnivas Laddad <ramnivas@xxxxxxxxx>]

You can do the following (although, I suspect, your real question
is of more general nature, so this may not help you):

aspect ConitionalExecution {
    pointcut inMethodABody() : withincode(String methodA());

    Object around() : call(* method3()) || call(* method4())) 
         && inMethodABody() {
         if(conditionA) {
              return proceed();
         }
    }

    Object around() : call(* method5()) 
         && inMethodABody() {
         if(!conditionA) {
              return proceed();
         }
    }
}
