Writing Adaptable Software - Mechanisms for Implementing Variabilities in Code and Models
Today, a software system is often a member of a system family. Members have many things in common and differ in a set of well-defined respects. These differences are called variabilities and must be implemented in the software system. This tutorial provides an overview over techniques available for implementing such variabilities. Various alternatives exist in programming languages such as preprocessors (as in C/C++), static metaprogramming (e.g. C++ templates), aspect-oriented programming (e.g. AspectJ and CaesarJ), polymorhpism and design patterns (such as Bridge, Strategy or Interceptor), reflection and dynamic metaprogramming (as in Ruby). In addition, variabilities can also be handled in models in the context of model-driven development, for example by connecting structural models with varability models, model weaving and AO techniques for model-to-model and model-to-code transformations. The first part of the tutorial is a discussion of the different kinds of variability as well as notations for describing each form.
The second part part will take a look at the different implementation techniques for variabilities in code and in models.
