摘要
程序切片能够提取出程序中影响关注点变量值的所有语句。程序切片分为粗粒度切片和细粒度切片。程序切片用在耦合性度量中能够估算信息流的总量,相比只查看有没有信息流存在的方法更精确。文中对基于切片的耦合度量算法进行了改进。提高了耦合度量算法的准确性。
The program slicing can extract all statements which affect the value of the variable concerned. The program slicing is divided into fine-grained slicing and coarse-grained slicing. The Coupling Metrics based on the program slicing can estimate the total amount of information flow, and therefore are more accurate than those who on- ly check whether the information flow exists or not. The slice-based coupling metric algorithm is improved with better accuracy in this paper.
