[06]Go设计模式:适配器模式（Adapter Pattern）

阅读更多关于 [06]Go设计模式:适配器模式（Adapter Pattern）

目录适配器模式一、简介二、代码三、参考资料适配器模式一、简介适配器模式（Adapter Pattern）是作为两个不兼容的接口之间的桥梁。这种类型的设计模式属于结构型模式，它结合了两个独立接口的功能。这种模式涉及到一个单一的类，该类负责加入独立的或不兼容的接口功能。例如：在现实生活中，我们的笔记本电脑的工作电压大多数都是20V，而我国的家庭用电是220V，如何让20V的笔记本电脑能够工作在220V的电压下工作？答案：引入一个电源适配器，俗称变压器，有了这个电源适配器，生活用电和笔记本电脑即可兼容。二、代码 package main import "fmt" // 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 // 不兼容而不能一起工作的那些类可以一起工作 // 定义一个新的接口 type Target interface { Process() } // 定义一个老的接口 type Adaptee interface { Foo() Bar() } // 定一个Adapter接口 type Adapter struct { adaptee Adaptee } func (a *Adapter) Process(){ fmt.Println("在Adapter中执行process()") a.adaptee.Bar() a

问题 From this I asked about controlling and highlighting a row. One of the answers was based on a custom adapter and I was given a series of links on how to do this. As I am trying to get my head around doing this, I first hit a problem getting a null pointer exception as listed in my linked post.
