【摘要】 构件提取是构件化技术中的一个热点问题,采用程序树作为代码构件的一种形式化表示,并使用结构化标记文法来解决构件提取中规则描述的问题,使得提取技术具有跨语言的能力,并给出了基于结构化标记规则的Ada代码构件提取过程实例。更多还原

【Abstract】 Component extracting is a focus in the component technology.In this paper,program-tree is used for formalized presentation of the code component,and structured markup grammar is applied to solve the description of rules in the rule-based component extracting.These denote the multi-language ability on the component extracting technology.An example,the process of Ada code component extracting based on structured markup rules is illustrated.更多还原
