通用文档浏览器的设计——WordViewer

Design of universal wordviewer

为了设计通用的文档浏览器,利用Java语言的平台无关和动态下载等特性,设计了对文档进行管理和操作的两个基本构件Document类和View类,并以Word文档为例,实现了Word文档和txt文档的电子浏览器——WordViewer。在不同的操作系统下进行了测试。测试结果证明,由Document/View类派生实现的WordViewer与运行平台无关。

In order to design an universal wordviewer, two basic components, document class and view class, were designed using two Java features of platform-independent and dynamic-download. Based on these two classes, wordviewer--an E-reader was developed for management and operation of word and text document. By extending the document/view class, it is proved that the wordviewer is platform-independent of operating systems.
