Patterns for re-usable aspects in object teams

Abstract

Aspect-oriented software development still lacks practical evidence. While aspects are claimed to be useful in adapting existing applications there is also first evidence that they might themselves be re-usable. We present results from two case studies with the aspect-oriented programming language ObjectTeams/Java that investigate the re-usability of aspects in developing a security framework. During the development of the framework we have identified patterns for re-usable aspects that increase the flexibility when applying a framework to a given application.
