Abstract: Design pattern plays a very important role in objectoriented software design, development and maintenance. In order to overcome the drawbacks and weaknesses of the previous methods for design patterns notation, SBPN，a stereotypebased pattern notation method was proposed. Based on the stereotype mechanism in Unified Modeling Language （UML）, SBPN provides some rules for labeling patternrelated information. It can not only identify precisely the role of a modeling element, such as a class, a method or an attribute in structural diagrams, but also label the information in interaction diagrams. Whats more SBPN provides a solution for labeling patternrelated information in source codes. Some cases were given to describe how to label patternrelated information in class diagrams, interaction diagrams and source codes, and a complex design diagram of sort system was also labeled by SBPN.

Key words: design pattern, Unified Modeling Language (UML), role, stereotype, pattern notation

摘要： 设计模式在面向对象软件设计、开发和维护中发挥着非常重要的作用。为了克服现有设计模式标注方法的缺陷与不足，提出一种基于衍型的模式标注方法SBPN。基于UML衍型机制，SBPN不仅提供了一套规则用于精确标注结构图中类、方法或属性等模型元素的模式角色相关信息，还可以标注交互图中的模式信息。此外，SBPN为源代码中模式信息的标注也提供了相应的解决方案。给出了使用SBPN方法标注类图、交互图和源代码中的模式信息的实例，最后还将SBPN应用于一个较为复杂的排序系统。
