Issue 3702:  tagged types mapped from abstract interfaces (ada-rtf)
Source:  (, )
Nature: Revision
Severity: Minor
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)
Resolution: Resolution:
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.”

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 the primitives of CORBA.Object.Ref (Is_A, Is_Equivalent, Hash)



Resolution:

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..
