摘要
通过对业务构件库中相似业务构件的共性部分和差异部分的分析和抽象,提出了一种可重用业务构件模型——元构件。利用设计模式和UML元元模型的扩展,给出了元构件的定义和语法描述,并对其参数进行了详细设计。最后,以一元构件为例证明了该方法的可行性。说明通过设计元构件的编译参数和运行参数可以提高业务构件的可重用性。
Based on the analysis and abstractness of commonness and otherness of similar business components in business component library. Meta-component, a model of reusable business component, is proposed. Firstly, the definition and syntax description of meta-component is presented by extending design pattern and UML meta-model. Secondly, the meta-component parameters are described in detail. Finally, the feasibility is proved by using unitary component as example. The results show that the reusability of business component can be improves by setting meta-component compiling parameters and running parameters.
