Research on Visitor Design Pattern

Abstract

Abstract: In the light of the object-oriented design principles, Visitor design pattern and its improved pattern are presented and analyzed. Then a new patter——reflect visitor pattern is put forward. The UML class diagrams and Java code fragments for each pattern are given.

摘要： 在面向对象设计理论指导下,通过分析Visitor设计模式及其已有改进模式的组成及其优缺点,提出了基于反射机制的改进方案Reflect Visitor模式。对于文中每一种模式,都给出了UML类图和Java实现的代码片断。

关键词: 设计模式, 面向对象, 软件复用
