- 3.3. 原型模式的适用环境
1. 简介
- 定义
- 使用原型实例指定待创建对象的类型,并且通过复制这个原型来创建新的对象。
- 使用场景
- 频繁创建"结构复杂的对象"
- 注意,克隆的对象是全新的对象,而且是独立的
2. 示例
using System;using System.Collections.Generic;using System.IO;using System.Linq;using System.Text;using System.Text.RegularExpressions;namespace ConsoleApplication4{ class Program { static void Main(string[] args) { GameSys sys = new GameSys(); sys.Run(new NormalActorA(), new FlyActorA(), new WaterActorA()); } } public class GameSys { public void Run(NormalActor normalActor, FlyActor flyActor, WaterActor waterActor) { NormalActor nActor1 = normalActor.Clone(); NormalActor nActor2 = normalActor.Clone(); NormalActor nActor3 = normalActor.Clone(); FlyActor fActor1 = flyActor.Clone(); FlyActor fActor2 = flyActor.Clone(); WaterActor wActor1 = waterActor.Clone(); } } #region 抽象类 public abstract class NormalActor { public abstract NormalActor Clone(); } public abstract class FlyActor { public abstract FlyActor Clone(); } public abstract class WaterActor { public abstract WaterActor Clone(); }
