【摘要】 论述了面向方面的编程(AOP)概念及其在处理横切关注点方面的优势,研究了其在程序状态可视化方面的应用,并利用AOP技术实现了一个表达式求值时的程序状态可视化的实例。程序状态可视化功能常常表现为一种横切关注点,相比利用面向对象的编程(OOP)来实现程序状态可视化功能,AOP技术提供了一种更加松耦合且更具模块性的实现方式。更多还原

【Abstract】 This paper described the concept of Aspect Oriented Programming(AOP) and its advantages of solving crosscutting concerns, discussed its application in the field of program condition visualization and presented an example of program condition visualization in the program of Evaluation of Expression by using AOP technology. The function of program condition visualization usually appears as crosscutting concern. Compared with Object Oriented Programming(OOP)technology, AOP technology provides a more loose-couple approach to modularize crosscutting concerns.更多还原
