Re: [ajdt-dev] passing context to advices
Ah, thanx Matthew, now i see..
so my code won't work then, because build and getItems have completely different parameters......

so how can i get the arguments of the withincode call? because those are the ones i need......

I assume if i use static JointPOint info to get Arguments,  i will still get argtuments for the pointcut
associated with call...

can you give me some more hints?

regards

Marco,

Yoy can't use call & execution together because that won't match anything. Using call & withincode is fine but to understand why it doesn't match we need to know the signatures of both getItems() and build(). The pointcut you end up with for your around advice is:

        call (* com.Manager.getItems(..)) && withincode(* com.ProcessorBean.build(..,DTO)) && args(demand);

So we are looking for a call to getItems() that takes a single argument of type DTO within a method build() that has at least one argument the last of which is also a DTO (because args goes with call not withincode) e.g.

     private void build (DTO dto) {
         Collection items = bean2.getItems(dto);
             
     }

        public Collection getItems (DTO dto) {
                return null;
        }

Use "call" or "execution" instead of "withincode". Withincode matches join points within the context of the function block, but you want to match on invocations of the function.

hello all,
i have following code which shows, in ajdt, no cross references..

  pointcut getItems() :
       call (* com.Manager.getItems(..));
   
   pointcut build(DTO demand) :
       withincode(* com.ProcessorBean.build(..,DTO))
       && args(demand);
   
   
   
   Object around(DTO demand) :
           (build(demand) && getItems()){
       System.err.println("We are there...");
       return proceed(demand);
   }





if instead i omit the DTO parameter (menaing, i don't pass as argument of my build pointcut, everything
works fine

anyone can tell me what's wrong? more likely i am using wrong syntax.....

thanx and regards
marco
