Abstract. This paper presents FeatureC++, a novel language extension to C++ that supports Feature-Oriented Programming (FOP) and Aspect-Oriented Programming (AOP). Besides well-known concepts of FOP languages, FeatureC++ contributes several novel FOP language features, in particular multiple inheritance and templates for generic programming. Furthermore, FeatureC++ solves several problems regarding incremental software development by adopting AOP concepts. Starting our considerations on solving these problems, we give a summary of drawbacks and weaknesses of current FOP languages in expressing incremental refinements. Specifically, we outline five key problems and present three approaches to solve them: Multi Mixins, Aspectual Mixin Layers, and Aspectual Mixins that adopt AOP concepts in different ways. We use FeatureC++ as a representative FOP language to explain these three approaches. Finally, we present a case study to clarify the benefits of FeatureC++ and its AOP extensions.

Collaborations are a frequently occurring class of crosscutting concerns. Prior work has argued that collaborations are better implemented using Collaboration Languages (CLs) rather than AspectJ-like Languages (ALs). The main argument is that aspects flatten the objectoriented structure of a collaboration, and introduce more complexity rather than benefits -in other words, CLs and ALs differ with regard to program comprehension. To explore the effects of CL and AL modularization mechanisms on program comprehension, we propose to conduct a series of experiments. We present ideas on how to arrange such experiments that should serve as a starting point and foster a discussion with other researchers.

“…The LoD states, "Only talk to your immediate friends," which implies that each unit of source code should only have limited knowledge about other units, and only about their so called friends. The LoD is an application of the low coupling principle by making the notion of bad coupling explicit and checkable by tools [4]. The LoD comes in two forms: The object form and the class form.…”

“…While the importance of these principles is beyond controversy, many different heuristics have been formulated that break down the difficult task of writing "good" code to a simple set of rules which developers can follow. One of those rules-of-thumb is the Law of Demeter (LoD), formulated by Lieberherr and Holland in 1989 [2], [3], [4]. Its intent is to achieve loose coupling by limiting the knowledge that one unit of source code has about other units in the system.…”

Abstract-The Law of Demeter formulates the rule-of-thumb that modules in object-oriented program code should "only talk to their immediate friends". While it is said to foster information hiding for object-oriented software, solid empirical evidence confirming the positive effects of following the Law of Demeter is still lacking. In this paper, we conduct an empirical study to confirm that violating the Law of Demeter has a negative impact on software quality, in particular that it leads to more bugs. We implement an Eclipse plugin to calculate the amount of violations of both the strong and the weak form of the law in five Eclipse sub-projects. Then we discover the correlation between violations of the law and the bug-proneness and perform a logistic regression analysis of three sub-projects. We also combine the violations with other OO metrics to build up a model for predicting the bug-proneness for a given class. Empirical results show that violations of the Law of Demeter indeed highly correlate with the number of bugs and are early predictor of the software quality. Based on this evidence, we conclude that obeying the Law of Demeter is a straight-forward approach for developers to reduce the number of bugs in their software.
