鸿蒙Next数据同步艺术：分布式数据对象的创建与管理 原创

import distributedObject from '@ohos.data.distributedDataObject';
// 定义分布式数据对象的类
class MyDistributedObject extends distributedObject.DistributedObject {
  constructor() {
    super();
    this.textData = '';
    this.numberData = 0;
  }
}
// 创建分布式数据对象实例
let myDistributedObject = new MyDistributedObject();

// 加入分布式网络
myDistributedObject.joinNetwork();
// 配置同步策略
myDistributedObject.setSyncPolicy({

  conflictResolution: (local, remote) => {
    // 自定义冲突解决逻辑
    return remote; // 以远程数据为准
