This paper describes the application of object-orientedprogramming to the design of a multiprocessor ESM testbed. The ESM testbed uses an object-oriented development environment which integrates Smalltalk and C langu...

Visual languages are loosely defined as interactive graphical methods of specifying to a computer some set of actions to perform. They are not just visual presentations nor simply the interactions necessary to operate...

This paper shows how an attempt at a uniform and reflective definition resulted in an open-ended system supporting ObjVlisp, which we use to simulate object-oriented language extensions. We propose to unify Smalltalk ...

Sloop is a parallel language and environment that employs an object-oriented model for explicit parallel programming of MIMD multiprocessors. The Sloop runtime system transforms a network of processors into a virtual ...

If the object-oriented style of programming hopes to live up to its potential as an improved methodology for software programming, a clear understanding of how to use types and inheritance is essential. Our experience...

The problem of developing a concurrency-control mechanism for a distributed object-orientedprogramming environment that allows several users on workstations to share objects in a transparent manner is addressed. An intuitive transaction model is obtained for the object-oriented environment that incorporates operation (method) inheritance with arbitrarily nested transactions. A simple implementation of the concurrency control mechanism, based on method-specific locking, is described. The approach can be applied to existing object-orientedsystems such as Smalltalk.
object-orientedprogramming is well-suited to such data-intensive application domains as CAD/CAM, AI, and OIS (office information systems) with multimedia documents. At MCC we have built a prototype object-oriented da...
