CarShop Example

This project can be self-instantiated (i.e., instantiation into the project, without driving a new project) or can be instantiated into a derived project (default usage scenario for product lines). This project demonstrates several modelling and instantiation concepts:

IVML Modelling Capabilities

Custom Data Type Definition: Definition of a positive Integer and an enumeration.
Abstract Compounds: Comparable with abstract classes.
Refined Compounds: Comparable with inherited classes.
Default Values: May be overwritten.

VIL Instantiation Capabilities

Advices: VIL script imports structure and data types defined in IVML model.
Dynamic Dispatch: Different instantiation functions are defined for the refined compounds. Correct function is automatically selected without need of instance checks and cast operations.
Syntax-based Modifications of Java-Code: Changes constant values via AST-operations.
Syntax-based Operations on XML-files: Selection of appropriate XML-files based on their content.

Scenario

The user may configure an engine specification and a window (title and dimensions). EASy-Producer will select car descriptions that match the selected criteria and configure an demonstrator that displays the selected cars.
