Feature-oriented programming with family polymorphism

Abstract

In feature-oriented programming (FOP), code clones are also important issue. Although an approach called a software product line (SPL) enables to implement products efficiently by reusing most of their code, SPLs implemented by FOP contain a lot of code clones. Code clones are often caused by alternative features and we also found clones in derivatives among alternative features. To resolve this problem, we propose a new FOP language named FeatureGluonJ, which supports family polymorphism with revisers. The code clones among alternative features are separated into another feature and can be shared among the alternative features by extending that feature. Furthermore, clones in derivatives can be removed as well.
