Hi all, I'm trying to learn AspectJ at the moment, am going through the documentation and have two questions, which I posted on StackOverflow initially. I'd appreciate if someone could help me.
How do I read pointcuts? === http://stackoverflow.com/q/28969333/2018047 This is basically about the example from https://eclipse.org/aspectj/doc/released/progguide/language-anatomy.html pointcut services(Server s): target(s) && call(public * *(..)) "This pointcut, named services, picks out those points in the execution of the program when Server objects have their public methods called. It also allows anyone using the services pointcut to access the Server object whose method is being called." I'm a bit confused how to read (and build up) pointcuts: the parameter list specifies a parameter s of type Server, yet the "source" for s seems to be the primitive pointcut target(s) - which hasn't executed yet, has it? The question basically boils down to: do you read/define pointcuts outside-in/left to right and execute them inside-out/right to left? Based on that, how do you build them up? (I have illustrated that bit of the question on StackOverflow with examples, to illustrate where my confusion comes from.) What does a return statement do in an AspectJ advice? === http://stackoverflow.com/q/28984838/2018047 I don't quite understand why the following line from a before advice requires a return statement - or what it does to begin with: System.out.println("Illegal value for x"); return; Will it basically "return form setX()" (the "intercepted" method) before the method body is executed? The full example is here: https://eclipse.org/aspectj/doc/released/progguide/language-interType.html#example-pointassertions Kind regards, Christian _______________________________________________ aspectj-users mailing list aspectj-users@eclipse.org To change your delivery options, retrieve your password, or unsubscribe from this list, visit https://dev.eclipse.org/mailman/listinfo/aspectj-users
