Enabling Expressive Aspect Oriented Modular Reasoning by Translucid Contracts

摘要

Making assertions about the program's control flow is important for reasoning purposes, e.g. ensuring that an advice proceeds to the original join point. Obliviousness of the base modules to the aspects in aspect oriented languages, like As-pectJ, makes it difficult to make such assertions in a modular manner. Base-aspect interfaces like crosscutting interfaces (XPIs), augmented with blackbox behavioral contracts save modularity of the reasoning process to some extent, but are not expressive enough to specify base-aspect control interactions in their full generality. Translucid contracts are proposed to specify and enforce typical control flow properties.
