Refactoring Aspect - Oriented Programs

Iwamoto Masanori, Jianjun Zhao

Abstract

Refactoring is the process of changing a program to improve its internal structure and reusability, without altering the external behavior of the program. It is a disciplined way to clean up code that minimizes the chances of introducing bugs. In this paper, we propose a systemic approach to refactoring aspect-oriented programs. To this end, we rst investigate the impact of existing object-oriented refactorings such as those proposed by Fowler [4] on aspect-oriented programs. Then we propose some new aspect-oriented refactorings that are unique to aspect-oriented programs. Finally, we discuss tool support for automatic refactoring of aspect-oriented programs. We use AspectJ, a general-purpose AOP language to demonstrate our approach, but our approach is general enough to be applicable to other AOP languages.
