HarmonyOS除了eventHub还有什么事件机制可以传递WrappedBuilder吗？

export const addInteractive = (model: InteractiveModel) => { 
  emitter.emit(InteractiveEvent.ADD, { data: model }) 
} 
export class InteractiveModel { 
  type: InteractiveType = InteractiveType.NONE 
  stick: boolean = false 
  reachType: ReachType = ReachType.ABOVE 
  builderWrap: WrappedBuilder<[ESObject]> = wrapBuilder(defaultBuilder) 
  param: ParamType = '' 
  constructor(type: InteractiveType, builderWrap: WrappedBuilder<[ESObject]>, param: ParamType = '') { 
    this.type = type 
    this.stick = InteractiveTypeMap[type].stick 
    this.reachType = InteractiveTypeMap[type].reachType 
    this.builderWrap = builderWrap 
    this.param = param 
  } 
}
