Towards Improved Class Parameterization and Class Generation in Modelica

Abstract

Class parameterization and class generation enhance the object-oriented means of Modelica, either by making them better accessible for the user or more powerful to apply for the library designer. Nevertheless, the current solution in Modelica does not properly distinguish between these two concepts, and hence it does not represent a fully satisfying solution. This paper presents a proposal or vision for a partial redesign of the language by separating class parameterization and class generation. In this way, the language becomes simpler and yet more powerful. The derived concepts may serve as guideline for future considerations of the Modelica language design.
