Re: [aspectj-users] Updating a returned variable

[Simone Gianni <simoneg@xxxxxxxxxx>]

Hi Breaks,
you can do this, again, with an around advice :

pointcut executionOfMyMethod() : execution(public MyObject TheClass.myMethod());

Object around() : executionOfMyMethod() {
  MyObject ret = proceed();
  ret.setAge(27);
  return ret;
}
