Controllers f reusable wrappers to adapt software components

摘要

This paper discusses the modular development of software applications in Open Systems using reusable components and controllers. In this work a component model for open system is proposed, in which components encapsulate computation, systems deal with the creation and communication of components, and the rest of the context-specific requirements and concerns are implemented by first--class, reflective. reusable entities, called controllers. Controllers are thought to be the natural evolution of the traditional object wrappers or filters to the realm of component-oriented programming, that can be added to components in a modular way, modifying their behavior according to the requirements they implement
