支持软件重用的程序设计语言

A PROGRAMMING LANGUAGE FOR SUPPORTING SOFTWARE REUSE

本文提出一种支持软件重用的程序语言（重用描述语言）并给出了重用描述语言翻译器的工作原理．该语言是在宿主语言Ｃ＋ ＋ 中引入“重用描述”成分和“装配语句”而形成的．该语言以软件重用部件库为依托，重用描述用于表达用户在程序中对部件的要求，重用描述语言翻译器则分析这些需求，自动在库中查找提出部件来适应用户．使用重用语言开发软件，使得程序员可以方便地重用软件重用部件库中的部件来开发新软件。

A programming language for supporting software reuse (Reuse Description Language) and the work principle of the translation system for the programming language are presented in this paper. The language is formed by introducing 'reuse description components' and 'assembly sentences' into C++ language. The language is based on a software reusable component library and reuse descriptions are used to express users' requirements for reusable components stored in the software reusable component library. The translation system for the programming language analyzes the requirements and automatically picks up the components from the library to meet these requirements of the users. By using the reuse description language, programmers can conveniently reuse the components in the library to develop new software, so that the productivity of software can be raised and the quality of software can be improved.
