Abstract:
As interest in components and composition-related methods is growing
rapidly, it is not always clear what the goals (and the corresponding
difficulties) actually are. If composition is to become central in
the future of software engineering, we need to better identify the
fundamental issues that are related to it, before we attempt to solve
them as they occur in object-oriented systems or in concurrent and
reactive systems. In this paper, we present our formulation of some
of the composition problems in a context of formal methods and program
specification and verification. This formalization is based on
predicate calculus and predicate transformers and aims at remaining as
general as possible. This way, we hope to better understand some of
the fundamental issues of composition and component-based reasoning.
