Abstract

We consider a system with a uniform object space. In a uniform object space, objects are the primary structural elements of the system. Such a system requires a different way of looking at the problem of sharing properties among objects. We describe the requirements on a suitable model of sharing and linguistic elements in the form of views and patterns to meet these requirements. With this model, we show that delegation both on the level of objects and as inheritance on the level of classes should only serve as a basis for implementing some of the linguistic elements of the model but not as such an element by itself. The model described in this paper finds itself in the language ARISTARCH/L which supports the object-based operating system ARISTARCH/OS that is under development in SAMOS, a project undertaken by the Operating Systems Research Group at the University of Karlsruhe.
