【摘要】 系统的某些关注点横切整个系统,无法很好地封装在单个模块里,造成代码混乱和弥散,用面向方面编程AOP可以解决这些问题。首先介绍了现代软件开发方法及其产生的问题;其次,阐述了AOP的基本概念,并结合AspectC++演示了如何进行面向方面的编程;再次,描述了如何对UML扩展以支持对方面建模;然后介绍了面向方面软件开发在实时系统中的应用;最后给出了结论和未来的主要工作。更多还原

【Abstract】 Some concerns crosscut all the system, which cannot be encapsulated in a module in a modular way, result in code tangling and scattering. Aspect-Oriented Programming(AOP) can modularize crosscutting concerns. Presents modern software development methodology and its shortage. Secondly this paper presents basic concepts of AOP, and demonstrates aspect- oriented programming using Aspect C++ . Thirdly UML extensions to model aspects are described. Fourthly this paper overviews application of AOSD in real-time systems. Finally conclusion and future focus are given.更多还原
