CORBA24 — value type substitutability

  • Key: CORBA24-47
  • Legacy Issue Number: 3072
  • Status: closed  
  • Source: UBS ( Hans Kneubuehl)
  • Summary:

    Chapter 5.2.5: Value type semantics should not define that an instance of a
    value type can be passed (directly) as a parameter that is declared as an
    interface type. The reason is that this is not true in some of the language
    mappings (e.g. C++) because it contradicts the kind and nature of value types.

    A value type instance IS NOT an object reference even if it is registered with
    the ORB. Therefore, if a construct conceptually is not a subtype of another
    construct, it should not be possible that it substitutes the other. Also, it
    should not be required that there are any shortcuts which automatically convert
    a registered valuetype to it's associated object reference.
