Abstract:
The diverse inheritance mechanisms provided by Smalltalk, Beta, and CLOS are interpreted as different uses of a single underlying construct. Smalltalk and Beta differ primarily in the direction of class hierarchy growth. These inheritance mechanisms are subsumed in a new inheritance model based on composition of mixins, or abstract subclasses. This form of inheritance can also encode a CLOS multiple-inheritance hierarchy, although changes to the encoded hierarchy that would violate encapsulation are difficult. Practical application of mixin-based inheritance is illustrated in a sketch of an extension to Modula-3. 1 Introduction A variety of inheritance mechanisms have been developed for object-oriented programming languages. These systems range from classical Smalltalk single inheritance [8], through the safer prefixing of Beta [12, 10], to the complex and powerful multiple inheritance combinations of CLOS [6, 9]. These languages have similar object models, and also share the view tha...
