Exceptions in guide, an object-oriented language for distributed applications

Abstract

This paper describes the design of an exception handling mechanism for Guide, an object-oriented language based on a distributed system. We confront the usual exception techniques to the object formalism, and we propose conformance rules and an original association scheme. A specific tool to maintain the consistency of objects in the face of exceptions is provided. System and hardware exceptions are integrated to the mechanism, and parallelism is handled in an original manner. Some details of the implementation are given.
