原先的struct A1变成了在A1文件里面的function harBuilder，这时我原先的A1要怎么处理？

@Component 
export struct CommunityBasePage { 
@State currentIndex : number = 0; 
//... 
}

@Builder 
export function harBuilder(value: object) { 
//。。。 
}

const builderName = BuilderNameConstants.HARA_A1; 
if (!RouterModule.getBuilder(builderName)) { 
  const builder: WrappedBuilder<[object]> = wrapBuilder(harBuilder); 
  RouterModule.registerBuilder(builderName, builder); 
}
