conn 结构体是Conn 接口的一个具体实现,它使用 netFD 对象来表示底层的文件描述符。 //Conn is a generic stream-oriented network connection.///Multiple goroutines may invoke methods on a Conn simultaneously.typeConninterface{Read(b []byte) (nint, errerror)Write(b []byte) (nint, errerror)Close(...
type NameObj struct { Name string } func(n NameObj) show(){ fmt.Println(n.Name) } struct 和 interface Golang中的interface是一个没有字段的,只有虚方法。interface的设计是为了补充struct。在Golang中 Structs: classes, with fields, ALL NON-VIRTUAL methods Interfaces: classes, with NO fields, AL...

注意:这几个函数非常有用,也是最常用的,由于Go语言泛型的局限性,Go语言方法不支持自己独立的泛型,所以导致用Stream中的方法转换只能用 interface{} 代替,这样会有个非常麻烦的问题就是,转换后用的时候必须得强转才能用,所以我把这些写成转换函数,就不会受制于类(struct) 的泛型了。 API功能说明 Map() 类型转换...

从这一点来看,我们可以把Go中的struct看作是不支持继承行为的轻量级的“类”。 从语法上看,Interface定义了一个或一组method(s),这些method(s)只有函数签名,没有具体的实现代码(有没有联想起C++中的虚函数?)。若某个数据类型实现了Interface中定义的那些被称为"methods"的函数,则称这些数据类型实现(implement)了...
