Abstract

Application classes participating as a role in some design patterns often implement both pattern- and application-related concerns. This tangling potentially makes classes more complex, more prone to changes and less reusable. This paper proposes an aspect-oriented solution that makes classes free of pattern-related code, whereas a connecting code concisely maps roles into classes. Developers having to modify the role of a class need only update such a connecting code, thus reducing changes to application code.
