HarmonyOS 是否支持自定义装饰器，如何实现？

//MyDescriptor.ets  
import { applyFunc } from './utils'  
  
export function MyDescriptor(target: Object, key: string, descriptor: PropertyDescriptor) {  
  const originalMethod: Function = descriptor.value  
  descriptor.value = (...args: Object[]) => {  
    console.log(`Calling ${target.constructor.name} method ${key} with argument: ${args}`)  
    const result: Object = applyFunc(originalMethod, MyDescriptor, ...args)  
    console.log(`Method ${key} returned: ${result}`)  
    return result  
  }  
  return descriptor  
}  
//utils.ts  
export function applyFunc(q: Function, w: any, ...args: any[]) {  
  return q.apply(w, ...args)  
}
