摘要
详细论述了组合(Composite)、桥接(Bridge)、观察者(Observer)、命令(Command)、外观(Facade)、装饰(Decora-tor)六种设计模式在GIS软件开发中的应用。旨在促使GIS开发中注重设计模式,努力发现、归纳并应用设计模式,实现软件设计的重用,提高GIS软件的质量和开发效率。
The application of Composite,Bridge,Observer,Command,Facade and Decorator patterns on the development of GIS Software is particularly analyzed in this article.The purpose of this article is to let us pay much attention to Design Patterns,and trying to find,summing up and making use of Design Patterns.As a result,the design experiences of GIS are reused,and then the quality and production efficiency of GIS software is improved greatly.
