HarmonyOS 如何获取一个对象内的所有变量

参考js的实现:

function getClassProperties(obj) {
  return Object.getOwnPropertyNames(obj);
}

// 示例用法
class MyClass {
  constructor() {
    this.property1 = "value1";
    this.property2 = "value2";
  }

  method1() {
  }

  method2() {
  }
}

const instance = new MyClass();
const properties = getClassProperties(instance);
console.log(properties); // ["property1", "property2", "method1", "method2"]
