Abstract: Refactoring is a key technique to acquire software quality. The traditional method of locating refactoring mostly relies on observations and subjective perceptions, which is inefficient. A method of locating refactoring based on slice metrics is proposed. It uses coarse-grained slice to measure the coupling of class and locate the classes which need refactoring. A case demonstrates that the method is efficient, and outperforms the conventional method.

Key words: coarse-grained slice, degree of coupling, refactoring location, Weighted Class Dependent Graph(WCDG)

摘要： 重构是提高代码质量的一项关键技术，传统的定位重构代码依赖开发者的观察和主观意识，效率较低。为此，将切片思想引入到重构定位中，提出一种基于切片度量的重构定位方法。该方法利用粗粒度切片度量软件系统中类和类之间的耦合度，并根据度量结果识别类间的“坏味道”，从而定位需要重构的类。实例研究表明，与其他方法相比，该方法能获得更优的性能。
