设计模式(Design pattern)是一套被反复使用、多数人知晓的、经过分类编目的、代码设计经验的总结。使用设计模式是为了可重用代码、让代码更容易被他人理解、保证代码可靠性。 毫无疑问,设计模式于己于他人于系统都是多赢的,设计模式使代码编制真正工程化,设计模式是软件工程的基石,如同大厦的一块块砖石一样。项目中合...

建造者模式(Builder Pattern),是创造性模式之一,Builder 模式的目的则是为了将对象的构建与展示分离。Builder 模式是一步一步创建一个复杂对象的创建型模式,它允许用户在不知道内部构建细节的情况下,可以更精细地控制对象的构造流程。 模式的使用场景 1.相同的方法,不同的执行顺序,产生不同的事件结果时; ...
