CORBA3 — IDL inheritance issue

  • Key: CORBA3-52
  • Legacy Issue Number: 4851
  • Status: closed  
  • Source: AT&T ( Duncan Grisby)
  • Summary:

    The IDL specification is unclear about the names that can be used to
    denote a base interface. Section 3.7.2 says

    "Each <scoped_name> in an <interface_inheritance_spec> must denote a
    previously defined interface."

    but the word "denote" is not defined. In particular, is the following

    interface I { };
    typedef I J;
    interface K : J { };

    There is real IDL in use in the world that assumes that inheriting
    from a typedef is permitted. I therefore suggest re-wording the part
    of section 3.7.2 to be

    "Each <scoped_name> in an <interface_inheritance_spec> must be the
    name of a previously defined interface or an alias to a previously
    defined interface."

    A similar clarification is required in section, regarding
    valuetype inheritance.
