Abstract
In object-oriented languages, multiple inheritance can cause ambiguities when methods of the same name are inherited from more than one superclass of a given class. In C++, qualifiers can be used to explicitly state which method should be inherited. We describe a mathematical foundation for an object-oriented language that uses qualifiers or roles to resolve such ambiguity. Our theory also allows us to model the role “super”. For languages with dynamic overriding [1], it further allows us to model monotonic inheritance of multi-valued methods. Finally, we describe a possible implementation of query evaluation in our language. This work extends that presented in [5].
