策略模式(Strategy Pattern) 概念 其思想是针对一组算法,将每一种算法都封装到具有共同接口的独立的类中,从而是它们可以相互替换。策略模式的最大特点是使得算法可以在不影响客户端的情况下发生变化,从而改变不同的功能。 特点 策略模式体现了面向对象程序设计中非常重要的两个原则: 封装变化的概念。 编程中使用...
使用Context来查看当它改变策略Strategy时的行为变化。StrategyPatternDemo.java publicclassStrategyPatternDemo{publicstaticvoidmain(String[] args){Contextcontext=newContext(newOperationAdd()); System.out.println("10 + 5 = "+ context.executeStrategy(10,5)); context =newContext(newOperationSubtract()); S...
策略模式的原理与实现策略模式,英文全称是 Strategy Design Pattern。在 GoF 的《设计模式》一书中,它是这样定义的: Define a family of algorithms, encapsulate each one, and make them interchangeable. Strategy lets the algorithm vary independently from clients that use it. 翻译成中文就是:定义一族算法类...

The main objective of this blog post is to give you an idea about Strategy Pattern to understand why you should use it and how to implement this pattern in Unity. Step 1 Introduction Don't know anything about patterns? Don't know how strategy pattern works? Wondering why you should use ...

I like explaining concepts with code examples and, since we shall see the use of strategy pattern in Angular later, the code examples here are in TypeScript. That being said, JavaScript implementation is quite similar. So, let's check out what the Avengers would look like, if they were re...
