Behavioral refinements of UML-statecharts

Szasz, Nora - Vilanova, Pedro

Resumen:

In [SV08] we have proposed a formalism for specifying the behavior of software product lines using UML-statecharts. Using an order relation among statecharts which represents when a statechart has a more complex structure than another one, we de ne how to combine diferent extensions of the same statechart into an integral new one. In this paper, we prove that the proposed extension constitutes a behavioral re nement. That is, whenever we allow the possibility of extending a given statechart, the old behaviour is preserved and new behavior may be added


En [SV08] proponemos un formalismo para especificar el comportamiento de líneas de productos de software utilizando UML-statecharts. Mediante una relación de orden entre statecharts que representa cuando un statechart tiene una estructura más compleja que otro, se define la forma de combinar diferentes extensiones de un mismo statechart en uno nuevo. En este trabajo probamos que la extensión propuesta constituye un refinamiento de comportamiento. Es decir, cada vez que se extiende un statechart, se preserva el comportamiento anterior, con la posibilidad de añadir nuevo comportamiento.
