动态图编辑器框架设计与实现

DESIGN AND REALIZATION OF DYNAMICAL GRAPH EDITOR FRAMEWORK

从具体的应用中抽象出适用于动态处理的图编辑器框架 ,并在此基础上利用 JAVA技术构造动态图编辑器API.它的开放结构允许应用程序在运行时动态扩展 ,使其一方面能够独立于应用程序 ,维护其自身的稳定性 ,另一方面又能够和应用程序有机地结合在一起 .它的模块化结构为应用程序提供了不同层次的切入点 .动态图编辑器框架作为可重用的设计 ,能够对相关领域图应用软件的研制起指导作用 ,在此基础上建立的图应用软件不但具有易扩展与维护的特点 。

This paper proposes a object oriented framework for dynamical graph editor. The framework is abstracted from different kinds of related applications. Its open environment can dynamically plug in different applications, which not only separate the dynamic graph editor from the applications, but also combine the dynamic graph editor with the applications. Its modular environment provides applications with different hotspots. As a reusable design, it can be used to designate many graph applications. Graph applications based on the framework are modular, flexible and maintainable, and can be completed in shorter time.
