| 中文摘要: |
| 本文论述用转换方式实现传统程序设计语言的面向对象扩充，给出了一组关键技术以解决由子类型多态和动态定连所引出的问题，其基本思想是将类和对象类型分开处理，从而避免转换过程中的重复工作．这些技术具有适用性强、功效高的特点，并且在ＰＡＳＣＡＬ语言的面向对象扩充ＮＤＯＯＰ和ＭＯＤＵＬＡ－２语言的面向对象扩充ＮＤＯＯＭ的实现中被采用，效果令人满意. |
| 英文摘要: |
| This paper describes a transformation approach to implementing object oriented extensions of traditional programming languages (OOGPLs), which OOGPLs are implemented using a preprocessor that translates from the program in OOGPL to an equivalent one in a traditional programming language. Some techniques are given to overcome difficulties with allowing polymorphism and dynamic binding. By them the authors have implemented NDOOP which is an object oriented extension of Pascal and NDOOM which is an object oriented extension of Modula 2. |
