Abstract

Standard class-based inheritance mechanisms, which are often used to implement distributed systems, do not seem to scale well to a distributed context with mobility. In this paper, a mixin-based approach is proposed for structuring mobile object-oriented code and it is shown to fit in the dynamic and open nature of a mobile code scenario. We introduce MoMi (Mobile Mixins), a coordination language for mobile processes that communicate and exchange object-oriented code in a distributed context. MoMi is equipped with a type system, based on polymorphism by subtyping, in order to guarantee safe code communications.
