Design patterns and pspects : modular designs with seamless run-time integration

textabstractSome solutions proposed in the original design pattern literature were shaped by techniques as well as language deficiencies from object-oriented software development. However, new modularity constructs, composition and transformation mechanisms offered by aspect-oriented programming address deficiencies of object-oriented modeling. This suggests classical design pattern solutions to be revisited. In our paper we point out that aspect-oriented programming not only allows for alternative representations of proposed solutions, but also for better solutions in the first place. We advocate a native aspect-oriented approach to design patterns that emphasizes on improving design pattern solutions both during development and at run-time. We use a simple yet effective method to analyze and describe different solutions on the basis of variation points, fixed parts, variable parts, and optional glue, employing dynamic run-time weaving
