Code generation in VUML profile: A model driven approach

VUML is a view-based analysis/design method offering a formalism (UML profile) and a process to model software systems through objects and views. The main extension to UML is the multiview class whose goal is to store and deliver information according to the user´s viewpoint. VUML supports the dynamic change of viewpoints and offers mechanisms to describe view dependencies. On the semantics side, the VUML meta-model extends the UML one with OCL rules. VUML proposes also a generic implementation pattern to generate the object code corresponding to a VUML class diagram. The proposed pattern uses delegation, handle technique and polymorphism to implement views. In this paper, we present a model driven implementation of this pattern, which integrates the multi-user aspect and supports Java language. We propose a code generation technique that respects the pattern and uses the MDA approach. We specify transformations as a collection of rules implemented in ATL. The proposal is illustrated by a simple example.
