Software variation by means of first-class change objects

By Peter Ebraert and Leonel Merino

Abstract

Abstract—A growing trend in software construction advocates the encapsulation of software building blocks as features which better match the language of requirements. As a result, programmers find it easier to design and compose different variations of their systems. Feature oriented programming (FOP) is the study domain that targets this trend. We argue that the state-of-the-art techniques for FOP have shortcomings because they specify a feature as a set of building blocks rather than a transition that has to be applied on a software system in order to add that feature’s functionality to the system. We propose to specify features as sets of first-class change objects which can add, modify or delete building blocks to or from a software system. We present ChEOPS, a proof-of-concept implementation of this approach and use it to show how our approach contributes to FOP on three levels: expressiveness, composition verification and bottom-up development. 1 SOFTWARE PRODUCT LINING CUSTOMERS are becoming more and more demanding and cost-conscious. They want specific products that exactly cope with their needs at the lowest cost possible. From the producers point of view, these two requirements are usually conflicting. The development of a specific product for one client takes a lot of time an
