Introducing Polymorphic Features into a Scripting Model of Generator

Generative programming is a discipline of Automatic programming which strives to make application and the generator development process flexible and generated program code optimized. Because of the lack of appropriate graphic and aspect based generator models, we developed the Scripting model of generator, as a static generator model based on higher level scripts. This paper gives a formal definition of the Scripting model and describes how basic object model properties, like encapsulation, inheritance, and now, polymorphism are achieved. This offers some advantages in generative application development, such as more precise application specification, better generator reusability, and simpler generator model and its easier implementation. The introduced polymorphic features are presented in an illustrative example of a Java application generator.
