【摘要】 反射是指系统可以感知外界环境变化并随之对自身实现进行相应调整。随着多媒体、实时和移动系统等对环境要求较高的应用的发展,中间件的"黑盒"模式已经不能满足这些新应用的需要,于是反射技术成为研究的热点。本文综述了反射技术的产生背景和研究现状,以及反射技术目前在中间件中的应用,介绍了相关研究项目和产品,最后对反射技术进行了总结和展望。更多还原

【Abstract】 Reflection refers to the capability of a system to reason about and acts upon itself. As for the development of multimedia,real-time and mobile applications,the black-box philosophy of conventional middleware doesn’t provide enough support for dealing with the dynamic aspects of these environment sensitive applications. Reflection becomes a hot research field. This paper first gives a retrospect to the background of reflection,then surveys some important research projects,and finally prospects the trend of this thechnology.更多还原
