基于规则的代码构件提取技术研究

Research on a Rule-based Code Component Extracting Technology

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。

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.
