面向对象程序可视化类图的逆向自动生成

Reversed Automatic Generation of Visualized Class Diagram of Object Oriented Program

研究了逆向构造程序类模型的基本规则，并且提出了一种可以自动绘制的、基于继承关系的层次型类图结构（ｉｎｈｅｒｉｔａｎｃｅｌａｙｅｒｅｄｃｌａｓｄｉａｇｒａｍ）．在这种层次型类图上，可以清晰地展示程序中的对象类及其相互之间的继承关系、组成关系和关联关系等，并可以直观方便地对程序中定义的对象类进行各种相关性或依赖性分析．文中还介绍了一个根据上述规则和方案实现的实用工具ＳａｆｅＰｒｏ／ＲｅＯＭ．

Reversed modeling is the critical technique in analyzing and understanding object oriented software, which is also the basis of its testing and maintenance.A set of basic rules for reversedly constructing program's class models are studied, and an inheritance layered class diagram is proposed, which can be drawn automatically. Kinds of relationship, such as inheritance, composition and association, can be shown in the layered class diagram. By the diagram, relativity and dependency among classes can be simply highlighted. In the end, the revised modeling tool, SafePro/Re OM, based on the set of rules, is presented.
