反省的对象中间件——理论与方法研究

Reflective Object-Oriented Middleware——Research on Theories and Methods

1 引言 现代软件系统必须能快速灵活地适应需求变化,换言之,系统要有灵活性和可重构性.同样,对中间件也如此.以往的研究表明,反省(Reflection)己被公认为是增加语言或系统灵活性与开放性的一种重要技术.近年来它开始向分布系统延伸,一些成果已初步证明了反省对提高分布系统,特别是中间件的灵活性是行之有效的.

Reflective computation is widely used in the field of programming language and operating system,and recognized as an important technology. To distributed system,especially middleware,reflection computation is however just a beginning. Considering our works during recent years. this paper shows the research on reflective object-oriented middleware, and firstly provides a collection of the methods on reflection based on the theoretical analysis.
