反射对象的概念、结构和实现

THE CONCEPT STRUCTURE AND IMPLEMENTATION OF REFLECTIVE OBJECTS

本文较系统地介绍了面向对象数据库语言ＲＯＬ中对象的计算反射的思想和实现方法．反射对象的引入是为了解决对象库中复杂的管理问题，并为设计智能化程度更高的对象提供一个良好的基础．本文还讨论了反射结构带来的问题，即封装性间题和效率问题，以及一种解决方法．

Within the paper the idea and some implementation technique of reflective objects in OOPL ROL are introduced systematically. The use of reflective objects is for the complicated management in OODB and for more intelligent behaviours of objects. The problems of encapsulation and efficiency arising from the introduction of reflection are also discussed with possible solutions.
