摘要
一种软件对数据标准的支持实际上就是支持对数据的读写,CIS(钢结构集成设计标准)标准作为一种新兴的、但相对稳定的标准数据结构也必然需要一种快速、有效的方法来实现其读写过程,但是目前国内对此研究的还非常少。基于此,在介绍CIS的同时,阐述了EXPRESS语言所对应的文本形式,并描述了其映射为文本文档的规则。着重讲述了如何把EXPRESS语言的文档解析成C++语言能够识别的数据。同时给出了读取CIS数据格式的具体实现方法,并以CIS系统中坐标点元素为例,详细说明了如何读取EXPRESS文档的方法及使用技巧,填补了国内空白,可供参考。
Supporting a data standard by a software actually means that it suppor ts the input/output of its data files.As a new and steady data standard,CIS ne eds a fast and effective method to input/output files.At present,the study is seldom in this field nationally.It is introduced an EXPRESS language of ste p and the file related to EXPRESS language.And the key target is to present the method to parse the EXPRESS file using C＋＋.A method is given to read the CIS data and a node is taken as example to show the skill of reading EXPRES S files,which may be referred by professional visitors.
