Using AOP to ensure component interactions in component-based software

Component-based software development (CBSD) has been got considerable adoption in software industry, but it is still lack of language support to ensure proper interactions among components, i.e. modularity assurance, which usually causes the software hard to maintain and evolve because of the improper dependencies among the components. In this paper, we propose an AOP approach to ensure that the interactions among components are strictly conformed to the sated API usage policies of the components. Also, by using AOP, we can separate the constraints violation checking code from the normal functional code via the so called aspects, thus improving the software quality by separation of concern. Experiment using AspectJ as the AOP implementation technique shows that the performance is comparable to the non embedded code.
