逆向工程中动态剧情的多重抽象方法研究

THE STUDY ON MULTIPLE METHODS OF DYNAMIC SCENARIO ABSTRACTION IN REVERSE ENGINEERING

动态信息是目标系统运行时行为特征的表现。从对软件的动态行为的可读视图(序列图)中,可以抽取出系统高层的动态模型,展示目标系统的高层体系结构。针对逆向自动生成的序列图,引入了多种对序列图的分割和抽象方法,帮助用户从不同的层次和不同关注点来分析动态信息,理解系统的动态行为。

The dynamic information is representation of the objective system character in system runtime. The dynamic model of system high-level architecture can be abstracted from readable view of software＇s dynamic behavior（ sequence diagram）, which can display the highlevel architecture of objective system. In the paper, sequence diagram that generated automatically should be separated and abstracted in multiple methods ,which helps users to analyze dynamic information from different levels and different points and to understand dynamic behavior of system.
