HarmonyOS如何获取一个类的父类名称

class Person { 
  name: string = ""; 
  constructor() { 
  } 
} 
export class HPerson extends Person { 
  constructor() { 
    super(); 
  } 
} 
export function log(): void { 
  let person = new HPerson(); 
  console.log(Object.getPrototypeOf(person).__proto__.constructor.name + "xxxxxxxxxxxxxxxx") 
}

class Parent {
  name: string;
  // 获取自身类名称
  currentClassName: string = this.constructor.name
  constructor(name: string) {
    this.name = name;
  }
}

class Child extends Parent {
  age: number;
  parentName: string = '';

  constructor(name: string, age: number) {
    super(name);
    this.age = age;
    // 获取父类名称
    this.parentName = super.constructor.name
  }
}


@Entry
@Component
struct Index {
  @State currentIndex: number = 2;
  childInfo: Child = new Child("小林", 24);

 build() {
    Column() {
      Text() {
        Span(`你好，我叫${this.childInfo.name}\r\n`)
        Span(`今年嘛，${this.childInfo.age}岁了\r\n`)
        Span(`本次测试，如下\r\n`)
        Span('子类获取父类的名称 super 实现实现类名获取 ' + this.childInfo.parentName + '\r\n')
        Span('父类获取自身名称 this.constructor 实现类名获取 ' + this.childInfo.parentName + '\r\n')
      }
    }
  }

class Parent {
    // 父类定义
}

class Child extends Parent {
    // 子类定义
}

// 获取父类的元组
let parentClasses = Child.__bases__;

// 遍历父类元组并打印每个父类的名称
for (let parent of parentClasses) {
    console.log(parent.__name__); // 打印父类的名称
}
