Implementation mechanisms and application of AOP

AOP (Aspect-Oriented Programming) is a technique for separation of crosscutting concerns which expresses higher abstraction level. AOP does for crosscutting concerns what OOP has done for object encapsulation and inheritance-it provides language mechanisms that explicitly capture crosscutting structure. A well-modularized crosscutting concern is called an aspect. This paper introduces the fundamental ideas of AOP, discusses the features, advantages and disadvantages of several typical implementation mechanisms of AOP according to the weaving of aspect code and component code. The prospect of the application and development direction of AOP is presented. This paper means to provide some references for further research on AOP.
