Modélisation par aspects et transformation vers AspectJ et Hyper/J

The use of the aspect-oriented concepts and mechanisms can improve the object-oriented design patterns implementation. However a certain lack of consensus on the basic aspect-oriented concepts and relations and the diversity of the suggested programming languages related to the Aspect approach, make it uneasy to express new pattern structures in a way that is not dependent from a specific programming language. We propose to avoid this difficulty by relying on a general meta-model for the aspect-oriented modeling that we worked out by identifying the common concepts and relations of both AspectJ and Hyper/J, two of the principal today aspect-oriented programming languages. This paper introduces this meta-model along with two meta-models that are respectively specific to AspectJ and Hyper/J. Transformation rules from a general model that is an instance of the general meta-model to the instance of one of the specific meta-model are also proposed. We illustrate this approach with the GoF Strategy pattern.
