ADA13 — tagged types mapped from abstract interfaces

  • Key: ADA13-9
  • Legacy Issue Number: 3702
  • Status: closed  
  • Source: Anonymous
  • Summary:

    The current Ada mapping specifies that ada Abstract_Ref types
    mapped from IDL abstract interfaces should inherit directly
    from CORBA.AbstractBase.Ref, and not from CORBA.Object.Ref.

    It seems more natural to us to make Abstract_Ref types inherit
    from CORBA.Object.Ref. Otherwise, these Abstract_Ref tagged
    types would not inherit thr primitives of CORBA.Object.Ref
    (Is_A, Is_Equivalent, Hash)

  • Disposition: Resolved — ADA 1.3
  • Disposition Summary:

    Close without change. The intended semantics for abstract interfaces are correctly
    reflected by inheriting from AbstractBase, rather than Object, as evidenced by the
    following section in the CORBA specification:
    “3. Abstract interfaces do not implicitly inherit from CORBA::Object. This is because
    they can represent either value types or CORBA object references, and value types do not
    necessarily support the object reference operations (see Section4.3, “Object Reference
    Operations,” on page4-8). If an IDL abstract interface type can be successfully narrowed
    to an object reference type (a regular IDL interface), then the CORBA::Object operations
    can be invoked on the narrowed object reference.”
    Disposition: Closed, no change
