Evaluation For The Reusability Of Aspect Oriented And Object Oriented Software Using Aspectj Programming Tools

Some concerns, such as debugging or logging functionality, can not be captured cleanly,and must be tangled and scattered throughout the code base. These concerns are calledcrosscutting concerns. Aspect-Oriented Programming (AOP) is a paradigm that enablesdevelopers to capture crosscutting concerns in separate aspect modules. The use ofaspects has been shown to improve understandability and maintainability of systems.It has been shown that real-time concerns, such as memory management and threadscheduling, are crosscutting concerns [4, 5, 7, 10]. However it is unclear whetherencapsulating these concerns provides benefits. We were interested in determiningwhether using AOP to encapsulate real-time crosscutting concerns afforded benefits insystem properties such as understandability and maintainability. This paper presentsresearch comparing the system properties of two systems: a real-time sentient trafficsimulator and its Aspect-Oriented equivalent. An evaluation of AOP is presentedindicating both benefits and drawbacks with this approach.
