Dear Ladies and Gentlemen:

I have a few suggestions concerning the Mapping of OMG IDL to 
Ada (chapter 23 of the CORBA V2.2 spec.)

My further suggestion is to adopt a single IDL specification as 
the basis for both the C++ and the Ada language mappings for the
interface Object (and other predefined interfaces). This is in
the interest of compatibility of programming interfaces.

In particular, I find the following methods lacking in the Ada
package CORBA.Object that are present in the C++ class Object:


// IDL               see OMG IDL to C++ Mapping, chapter 20.32.1
interface Object
{
    // [...]

    boolean is_a(in string logical_type_id);
    boolean non_existent();
    boolean is_equivalent(in Object other_object);
    unsigned long hash(in unsigned long maximum);

    Status create_request2(
        in Context ctx,
        in Identifier operation,
        in NVList arg_list,
        in NamedValue result,
        in ExceptionList exclist,
        in ContextList ctxlist,
        out Request request,
        in Flags req_flags
    );
    Policy_ptr get_policy(in PolicyType policy_type);
    DomainManagerList get_domain_managers();
    Object set_policy_override(in PolicyList policies,
                               in SetOverrideType set_or_add);
};



I have so far only looked into the interface Object, but suspect
that further omissions exist in other predefined Ada packages.

Thus, my final suggestion is to review the entire Ada predefined
language environment (chapter 23.8) with respect to updating it
to that defined for C++.
