方法封装& C' s0 z# d! c3 y$ G
上述是对文档操作的基本方法,在实际项目开发中,该类操作使用比较频繁,通常只需要获取相应的指针即可,如对本地模型的特征操作,我们需要加载本地模型文档——获取其文档指针——获取其容器——获取其根节点。每次操作都是这关键的几个步骤,不同之处在于模型的本地路径,以及相应的模型在模型树上的根节点。因此,我们可以对文档加载方法进行封装,即输入设置为文档路径,输出为该模型在模型树上的根节点指针。如“打开文件”操作,封装成OpenCATFile方法如下. ~. a0 Q1 B7 t' r, s8 E
输入:* E- C! K# N( }0 O! u
CATUnicodeString PathName //文档(模型)的路径/ X v2 G3 c& n& T
