【摘要】 在程序理解和逆向工程中,对软件设计模式的识别有助于软件技术人员从软件结构上理解系统的设计意图和实现功能。通常,采用UML类图表示的软件设计描述难以从特征上对设计模式进行准确的识别。提出一种基于XML Schema技术定义XML文档结构的设计模式定义语言——DPDLXS。通过运用DPDLXS语言描述特定设计模式的实例表明,该设计模式定义语言能够准确表述设计模式的特征,可以为设计模式的识别提供技术支持。更多还原

【Abstract】 The identification of software design patterns can help software technical personnel understand the system’s design intent and function from the software structural in program comprehension and reverse engineering.Generally, the software design information in the form of UML class diagram representation is hard to identify design patterns accurately from the pattern feature.This paper proposed a design patterns definition language can based on XML Schema—DPDLXS.The representation of specific design patterns instance by using DPDLXS language shows that the language can portray the feature of design patterns accurately,and provide a technical support for the identification of design patterns.更多还原
