A Static Extension of DynAMiT
(Softwaretechnik-Trends Band 25, Heft 2, 2005) Breu, Silvia; Dörre, Jens
Recently, Aspect-oriented programming (AOP) has been used for reengineering. The major task here is to find and isolate crosscutting concerns, which is called aspect mining. Detected concerns can be re-implemented as aspects, which reduces complexity and improves maintainability and extensibility of software systems. Several techniques have been proposed for aspect mining, including our DynAMiT approach. It mines aspects in program traces that are generated during program execution. These traces are investigated for recurring patterns of execution relations. The dynamic analysis approach has been chosen because it monitors actual program (i.e., run-time) behaviour instead of potential behaviour, as static program analysis approaches do. However, DynAMiT’s dynamic analysis has limitations that are partly due to dynamic binding at run-time. These can lead to the identification of aspect candidates that have already been encapsulated properly following object-oriented design principles. This paper describes a static extension of the approach that mitigates this problem.
