摘要
介绍设计模式的概念以及封装变化的思想,结合铁路调度指挥系统的特点,详细说明了工厂方法、观察者和单件模式的典型应用场景,以及设计模式的综合应用。
The authors firstly introduced the concept of design patterns and the thought of change of encapsulation.Based on the features of railway dispatching command systems,the model scenario of three design patterns,namely factory method,observer,and singleton were illustrated and the synthetic application of design patterns were dealt with.
