一种静态的Java程序函数调用关系图的构建方法

摘要

在程序理解中,函数之间的调用关系是程序理解研究的重要内容.一个函数往往代表了一种具体功能或问题求解的实现,构建出函数调用图有助于对程序的理解.以JAVA语言为研究对象,介绍了几种函数调用图的构建方法,并比较了它们的优劣性,并在此基础上提出了一种函数调用图的构建方法%n program understanding the research of function relationship occupies a very important position. A function often represents a specific performance or problem solving realization. The constructing of function invocation figure is very helpful to the understanding of program. This paper uses Java as research object, introduces several construction methods of function's call graphics and compares with their inferiority and proposed in this foundation a function call figure building methods
