HarmonyOS关于TS转ArkTS的语法问题

const decoratedClassesInstances: any[] = []; 
function SpecificDecorator(): ClassDecorator { 
  return function(target: Function) {   decoratedClassesInstances.push(Reflect.construct(target, [])); 
  }; 
} 
@SpecificDecorator() 
class MyClass2 { 
  sayHello() { 
    console.log('Hello from MyClass2'); 
  }

// 定义一个全局数组，用于存储被特定装饰器装饰的类的实例 
const decoratedClassesInstances: Object[] = []; 
// 定义一个装饰器 
function SpecificDecorator(o:object): ClassDecorator { 
  return (target: Function) => { 
    // 将被装饰的类的实例化对象添加到数组中 
    console.log(JSON.stringify(o)) 
    decoratedClassesInstances.push(o); 
  }; 
} 
@SpecificDecorator(new MyClass2()) 
class MyClass2 { 
  id:number = 1111 
  sayHello() { 
    console.log('Hello from MyClass2'); 
  } 
} 
@SpecificDecorator(new MyClass3()) 
class MyClass3 { 
  id:number = 2222 
  sayHello() { 
    console.log('Hello from MyClass2'); 
  } 
}
