How do I translate this to CORBA-style interfaces. CORBA interfaces
don't have a base type like all COM interfaces have (eg: IUnknown) or
objects have (eg: TObject).
Any ideas on how I should translate the above code? Must I use the
Pointer type again? That just looks ugly, and gives no hint to the
developer that Update() can take any interface type.
I personally would declare my own basic interface class and derive all
other interfaces from that... This of cours only works if anyone adheres
/ can adhere to that rule.
Why couldn't CORBA interfaces also descend from IInterface, but in the
case of CORBA style interfaces that doesn't mean it's a IUnknown
descendant. That way we will have a generic interface type to use in
such generic code situations.
Because IInterface is designated as a COM-interface and you can't
descend a CORBA-interface from a COM-interface or vice-versa. Also it's
not possible to declare IInterface as a CORBA-interface, because another
unit might use COM-interfaces and then the COM-style IInterface is needed.
