定义：

将一个类的接口转换成客户希望的另一个接口。adapter模式使得原本由于接口不兼容而不能在一起的那些类可以一起工作。

 

示例代码：

1、类适配器

/*Class Adapter:类适配器，这里简写为CA通过适配器PowerAdapter_CA类，将两孔插头TwoHole_CA类进行封装，从而得到我们想要的三孔插头ITargetThreeHole_CA类，*/public interface ITargetThreeHole_CA  {    void Request();}

 

using UnityEngine;public class TwoHole_CA {    public void SpecificRequest()    {        Debug.Log ("我是两孔的插头");    }}

 

using UnityEngine;public class PowerAdapter_CA : TwoHole_CA,ITargetThreeHole_CA {        public void Request ()    {        Debug.Log ("将");        SpecificRequest ();        Debug.Log ("转换为三孔插头了");    }}

 

using System.Collections;using System.Collections.Generic;using UnityEngine;public class Client_CA : MonoBehaviour {    void Start () {        ITargetThreeHole_CA threeHole = new PowerAdapter_CA ();        threeHole.Request ();    }}

 

2、对象适配器

/*Object Adapter:对象适配器，这里简写为OA通过适配器ITargetThreeHole_OA类，将两孔插头TwoHole_OA类进行封装，从而得到我们想要的三孔插头PowerAdapter_OA类，*/public interface ITargetThreeHole_OA  {    void Request();}

 

using UnityEngine;public class TwoHole_OA {    public void SpecificRequest()    {        Debug.Log ("我是两孔的插头");    }}

 

using UnityEngine;public class PowerAdapter_OA : ITargetThreeHole_OA {        TwoHole_OA twoHoleAdaptee=new TwoHole_OA();    public void Request ()    {        Debug.Log ("将");        twoHoleAdaptee.SpecificRequest ();        Debug.Log ("转换为三孔插头了");    }}

 

using UnityEngine;public class Client_OA : MonoBehaviour {    void Start () {        ITargetThreeHole_OA threeHole = new PowerAdapter_OA ();        threeHole.Request ();    }}
