Abstract: Function Point Analysis（FPA） can only measure the static aspects of systems and can not take the interactions and behaviors of objects into consideration.So，according to the characteristic of object-oriented systems，this paper presents an Object-Oriented Method Function Point（OOMFP） method based on FPA and completes the mapping from the concepts and measurement rules of FPA to object-oriented methods.Finally，the detailed measurement process is given.This method establishes the firm theoretic foundation for Web metrics.

摘要： 功能点分析（FPA）本身只能度量系统静态的方面，不能考虑到对象的交互性和对象的行为。基于FPA，结合面向对象系统的特点，提出了一种面向对象方法的功能点，完成了从FPA方法到面向对象方法概念上的映射和度量规则上的映射，并给出了该方法具体的度量过程，为Web应用的度量奠定了坚实的理论基础。
