//类装饰器
const mylog2: ClassDecorator = (target) => {
  console.log(target, "target")

  target.prototype.one = "一个" //原型写入一些属性

}

//参数装饰器
const paramsLog: ParameterDecorator = (...rest) => {

}

//属性装饰器
const nameLog: PropertyDecorator = (target, propertyKey) => {
  console.log(target, "target-nameLog")
  console.log(propertyKey, "propertyKey-nameLog")
}


@mylog2
class mycbd implements mycbdInterface {
  @nameLog
  myname: string = "abc"

  @myconsole
  alert(@paramsLog name: string) {

  }

}

let tabc: mycbdInterface = new mycbd;

console.log(tabc.one) //打印出一个

console.log(tabc, "tabc")

tabc.alert("我传入的")
