软件连接件的分类及其应用研究

On the Classification of Software Connectors and their Applications

1引言 连接件在软件体系结构中占有重要的地位.绝大部分的软件体系结构分析方法,均把连接件作为一个单独的实体进行分析.把原本分散在系统各个部分的连接成分,组成一个单独可见的实体,并把它提到与组件相同的重要程度,这是软件体系结构分析的重要成果之一[1,2].

That a connector's structure should consist of an implementation structure and a protocol structure is suggested in this article. For the practice purposes,all connections are divided into six styles in the view of implementation structure. For control connection styles,they consist of synchronous.and asynchronous connections by time.and soft-connection and hard-connection by space. And for data connection styles, they only consist of soft and hard connections. Specially,the difference between soft connection and hard connection,though it could not be obviously distinguished by some formal ADL(Architecture Description Language) .could influences the software architecture intensely. From it ,a new method of metricating the complexion of software architecture is proposed.
