A UML Precise Specification of Design Patterns Using Decoupling Constraints

Overview UML collaboration templates do not capture the problem part of design patterns. It is then possible to apply a pattern solution in contexts that are not consistent with this solution. Moreover, when the context evolves, it must stay consistent with the patterns that were previously applied. Since design problems can be quite varied, the paper focused on one of the most frequent design goals of design patterns: avoiding unnecessary coupling. This paper adapts the notion of decoupling constraints to UML models and it expresses it using the Object Constraint Language. Adding decoupling constraints to collaboration templates allows checking if a context is consistent with the solution of a pattern and eases the adaptation of this solution to an evolving context.
