Using Jaza to Animate RoZ Specifications of UML Class Diagrams

One of the goals of the integration of formal and graphical methods is to reuse tool support associated with formal methods. This paper reports on a combination of the Jaza Z animator with the RoZ tool. RoZ produces a Z specification from an annotated UML class diagram. It also generates the specification of basic operations associated to the diagram. The paper recalls the principles of the RoZ tool, gives a typical animation session, and discusses how RoZ and class diagrams must be adapted to support animation
