[aspectj-users] identifying a call within a method and harvest the param

[robert kuzelj <robert_kuzelj@xxxxxxxxx>]

hi,

i want to weave something around a call to a
method where the result of the around advice is dependent
on a paramater value given to the calling method.

<code>
public class Processor
{
  public Result process(Parameter _param)
  {
    ...
    Value val = createValue();
    ...
  }

  public Value createValue()
  {
    return null;
  }
}
</code>

now i want to do something like this

<code>
public aspect ProcessCreation
{
   pointcut creation(Parameter _param):
      withincode(public Result Processor.process(Parameter))
   && args(_param)
   && call(public Value Processor.createValue());

   Value around(Parameter _param): creation(_param)
   {
      Value result = null;
      if (_param.getValue() == 0)
      {
         result = new Value("OK");
      }
      else
      {
         result = new Value("FAILED");
      }
      return result;
   }
}
</code>

the problem is that as soon as i try to harvest the parameter
from the surrounding method the advice gets not executed anymore
(meaning the pointcut is not matched of course).

anybody any idea?

ciao robertj
