一种基于四层结构的构件库模型研究

Research on a Component Library Model Based on Four-Layer Architecture

文章提出了一种基于四层结构的构件库模型,并按照构架层、构件层、叶类层、叶函数(叶方法)层的层次结构管理可复用构件。并且对于各层实体的描述形式作了进一步的研究,说明了构架、构件、类、函数(类方法)的描述属性以及它们之间的关系,促进更有效地组织和管理可复用构件,从而支持构件使用者更好地检索、理解和选取构件。

In this thesis,a component library model based on four-layer architecture is presented.Four-layer architecture includes framework layer,component layer,leaf-class layer and leaf-function(leaf-method)layer.The component library is hierarchically constructed.The component attribute description in different layers and the relationship with other compo-nents are studied and defined.This is helpful for system manager to organize and manage the component library more efficiently.And this is helpful for users to retrieve,comprehend,and reuse components.
