我们来看看lua vm在解析下面源码并生成bytecode时的整个过程: foo = "bar" local a, b = "a", "b" foo = a 首先我们先使用ChunkySpy这个工具来看看vm最终会具体生成什么样的vm instructions 在这里,开头为[数字]的行是vm真正生成的字节码,我们看到一共生成了六行字节码.首先loadk将常量表中下标为1的常量即"bar"赋给寄存器0:然后setglobal将
package main import "fmt" type user struct { name string age int sex string } type admin struct { person user level string } func main() { u := user{name: "zhangsan", age: 12, sex: "女"} u.userReciver("里默默") //Go在代码背
继承会发生在子类和父类中,如图所示,是一系列类的继承关系类图,Person是类层次结构中的根类,Student是Person的直接子类,Worker是Person的直接子类.这个继承关系类图的具体实现代码如下: class Person { var name : String var age : Int func description() -> String { return "\(name) 年龄是: \(age)" } convenience init () { self.
