| 摘 要： | 内聚度是指模块内各成分之间的联结强度。在面向对象软件系统中,内聚度主要是指类内部的属性和方法之间的联结强度。在类依赖图的基础上,提出了一种基于结构熵类内聚度度量方法,从类的属性与属性、属性与方法和方法与方法之间依赖关系3个方面对类的内聚度进行度量。并综合以上3种内聚度给出了一个类内聚度的度量方法,为评价类的内聚度提供了指南。

| Abstract: | The cohesion represents the tight degree of the components of a software module.In an object-oriented environment,the cohesion means the tight degree among the attributes and methods in a class.Based on the class dependence graph and structure entropy,a new method is proposed to measure the cohesion of a class.This method measures the cohesion between attributes and attributes,attributes and methods,methods and methods of a class.The proposed method provides a guideline for evaluating the cohesion of a class. |
