【摘要】 从软件开发方法学的角度探讨AOP为何成为结构化或者面向对象技术的补充,它怎样提供对横切关注点的标识、分离和封装技术;然后论述AOP的有关概念,支撑结构,优缺点等.并结合开发一个对C语言扩展的AOP系统的具体实践,阐明和总结要实现一个AOP语言所要涉及到的关注点和方面的封装、描述,方面代码的编译,静态或动态织入方面代码等关键技术.更多还原

【Abstract】 This paper tries to discuss why AOP emerges as a complement to structural or object oriented programming and how it provides the means for cross-cutting concerns identification,separation and encapsulation,from software methodology perspective;then describes the related concepts,supporting architectures,benefits and drawbacks of AOP.Moreover,the key technique issues of how to design and implement an AOP language are presented,especially on the crosscutting-concerns encapsulation,aspect-code compilation and static or dynamic weaving techniques.These issues are what we have encountered in the design and implementation of a practical AOP language which can manipulate the internal structure of C programs and can be used for software security engineering.更多还原
