设计模式在基于组件的框架设计中的应用

框架是一种面向对象的软件重用技术。组件是一种比对象类的粒度更大的软件重用模块。基于组件的框架建筑在面向对象技术之上,但更具有抽象性和重用性。设计模式有助于获得无需重新设计就可适用于多种应用的框架体系结构。该文结合一个实例详细描述设计模式在组件框架建模中的作用,并给出了所得应用框架的逻辑结构。

Application of the Design Pattern in Designing Component-based Frameworks

Frameworks are an object-oriented reuse technique.Components are bigger scale reusable module than ob-jects.Component-based frameworks build on OO technologies,creating a better case of potential reuse and abstraction.In general,a mature framework includes many patterns.The frameworks using pattern can suit many applications,and don't need to rebuild.Using an example,this paper discusses how to use patterns in designing Component-based frameworks,and the structure of framework is illustrated.
