HarmonyOS ArkUI的自定义装饰器能否实现java那种运行时注解的功能

可以根据传入的字符串动态去掉用对应的方法：

@Entry
@Component
struct DynamicFuntionDemo {
  @State message: string = 'Hello World';

  build() {
    Column() {
      Text(this.message)
        .id('DynamicFuntionDemoHelloWorld')
        .fontSize(50)
        .fontWeight(FontWeight.Bold)
        .alignRules({
          center: { anchor: '__container__', align: VerticalAlign.Center },
          middle: { anchor: '__container__', align: HorizontalAlign.Center }
        })
      Button('动态调用函数')
        .onClick(() => {
          let demo = new dddd()
          demo.fun['ssss']()
          demo.fun['sdss']()
        })
    }
    .height('100%')
    .width('100%')
  }
}

export class dddd {
  fun: Record<string, Function> = {};

  constructor() {
    this.fun = { 'ssss': this.ddd1, 'sdss': this.ccc }
  }

  ddd1() {
    console.log('ddd1')
  }

  ccc() {
    console.log('cccc')
  }
}
