accessing members of object implmentation

[Bernd Daum]

Hi everybody,

i am trying to build a wrapper for an object
storing in an object oriented database.

I added (comparing with the IDL-interface) data members
to the object implementation, which are not visible for
the Corba-Client.

My problem now is, that the server should access
and manipulate the data members (in my case a reference
to a persistent database object) of the object
implementation.

The server has a reference (from type _ptr) to the actual
object but this is the parent class, which doesn't know
about the added data members.

Is there anybody, who know a CORBA-like solution.

Thank you in advance.

Example:

**** IDL  ***

interface A;

interface A_Factory {
	A newA();
	manipulate(in A aref);
}


**** C++ ***

class A_i:public virtual _sk_A {
public:
	Flout added_data;        //added member

}


class B_Factory: public virtual _sk_B_Factory {
           .
           .
manipulate(A_ptr aref) {
  aref->added_data++;     // making  something with added_data:


// this doesn't work, because 'added_data'
// is no visible member of A.
