Parallel Composition of Aspect Mechanisms: Design and Evaluation

Abstract: There is a growing interest in the composition of aspect mechanisms. All extant works, however, avoid an important question: what should the semantics of the composed multi-extension language be? The problem is that the semantics for the composition is nowhere specified. Therefore, even if third-party composition of aspect mechanisms were successful, it is difficult to evaluate the correctness of the composition. In this paper, we propose the use of AspectJ 5 as a benchmark for evaluating and comparing composition techniques for integrating pointcut-and-advice mechanisms. If an aspect mechanism X implements the semantics of AspectJ and another mechanism Y implements the semantics of AspectWerkz, then the semantics of the composition X+Y can be checked against the semantics of AspectJ 5. We present a novel parallel composition technique, and illustrate that it passes the AspectJ 5 benchmark.
