一、引言 “结构型”的设计模式已经写完了,从今天我们开始讲“行为型”设计模式。现在我们开始讲【行为型】设计模式的第一个模式,该模式是【模板方法】,英文名称是:Template Method Pattern。还是老套路,先从名字上来看看。“模板方法”我第一次看到这个名称,我的理解
模板方法(Template Method) 模板方法是一种行为设计模式,它在超类中定义了一个算法的框架,允许子类在不修改结构的情况下重写算法的特定步骤。 模板是对多种事物的结构、形式、行为的模式化总结,而模板方法模式(Template Method)则是对一系列类行为(方法)的模式化。我们将总结出来的行为规律固化在基类中,对具体的行为...
