9508 :: How to check if an object is a child (Similar behavior of instance of from Java)

• tmiwata (orginal) [2022-10-06T10:24:30+02:00] view original

  For example I have 3 object.

  1. Parent Obj
  2. Child Obj = ref object of Parent Obj
  3. secondChild Obj

  proc getProcess*(): Parent Obj =

  if process1

  return Child Obj

  if process2

  return secondChild Obj

  and so on..

  Question: I want to check if the getProcess returned object is Child Obj, Because when I'm trying to check in unit testing it always says its Parent Obj. I just want to know if there is same as instance of from Java, to check its reference.

  FYI: I am using Testament.

  Use the of operator to check if something is an instance of a runtime type.
