Re: [aspectj-users] pointcut to match a specific object in argument

You're right that you have to enumerate -- first, second.. last: 

  (execution(* *(Order, ..)) && args(order, ..))
  || (execution(* *(*, Order, ..)) && args(*, order, ..))
  || (execution(* *(*, *, Order, ..)) && args(*, *, order, ..))
  ... for as many places as you need, then
  || (execution(* *(.., Order)) && args(.., order))
