+# 分布式数据对象
+## 简介
+分布式数据对象管理框架是一款面向对象的内存数据管理框架，向应用开发者提供内存对象的创建、查询、删除、修改、订阅等基本数据对象的管理能力，同时具备分布式能力，满足超级终端场景下，相同应用多设备间的数据对象协同需求。
+
+分布式数据对象提供JS接口，让开发者能以使用本地对象的方式使用分布式对象。分布式数据对象支持的数据类型包括数字型、字符型、布尔型等基本类型，同时也支持数组、基本类型嵌套等复杂类型。
+
+## 约束
+
+• 不同设备间只有相同bundleName的应用才能直接同步
+
+• 不建议创建过多分布式对象，每个分布式对象将占用100-150KB内存
+
+• 每个对象大小不超过500KB
+
+• 支持JS接口间的互通，与其他语言不互通
+
+• 如对复杂类型的数据进行修改，仅支持修改根属性，暂不支持下级属性修改
+

+## 接口说明
+
+### 引用分布式对象头文件
+
+```js
+import distributedObject from '@ohos.data.distributedDataObject'
+```
+
+### 接口
+
+| 接口名称 | 描述 |
+| ------------------------------------------------------------ | ------------------------------------------------------------ |
+| function createDistributedObject(source: object): DistributedObject; | 创建分布式对象
source中指定分布式对象中的属性
返回值是创建出的分布式对象，接口见DistrubutedObject |
+| function genSessionId(): string; | 随机创建sessionId
返回值是随机创建的sessionId |
+
+### DistrubutedObject
+
+| 接口名称 | 描述 |
+| ------------------------------------------------------------ | ------------------------------------------------------------ |
+| setSessionId(sessionId?: string): boolean; | 设置同步的sessionId,可信组网中有多个设备时，多个设备间的对象如果设置为同一个sessionId,就能自动同步
sessionId是不同设备间组网的标识，将sessionId设置为" "或不设置均可退出组网
返回值是操作结果，true表示设置sessionId成功 |
+| on(type: 'change', callback: Callback<{ sessionId: string, fields: Array }>): void; | 监听对象数据的变更
type固定为'change'
callback是变更时触发的回调，回调参数sessionId标识变更对象的sessionId,fields标识对象变更的属性名 |
+| off(type: 'change', callback?: Callback<{ sessionId: string, fields: Array } | 删除数据对象变更的监听
type固定为'change'
callback为可选参数，不设置表示删除该对象所有变更监听 |
+| on(type: 'status', callback: Callback<{ sessionId: string, networkId: string, status: 'online' \| 'offline' }>): void | 监听数据对象上下线的变更
type固定为'status'
callback是变更时触发的回调，回调参数sessionId标识变更对象的sessionId，networkId标识对象设备的networkId，status标识对象为'online'(上线)或'offline'(下线)的状态 |
+| off(type: 'status', callback?: Callback<{ sessionId: string, deviceId: string, status: 'online' \| 'offline' }>): void | 删除数据对象上下线变更的监听
type固定为'change'
callback为可选参数，不设置表示删除该数据对象所有上下线监听 |
+| save(deviceId: string, callback: AsyncCallback<SaveSuccessResponse>): void | 持久化保存数据对象
deviceId为设备Id，用户自定义。例如"local"。
|
+| revokeSave(callback: AsyncCallback): void | 撤回已保存的数据对象。
type固定为'change'
callback为撤回已保存的数据对象回调 |
+
+
+
+## 开发实例
+
+针对分布式数据对象，有以下开发实例可供参考：
+
+[备忘录应用](https://gitee.com/openharmony/distributeddatamgr_objectstore/tree/master/samples/distributedNotepad)
+
+分布式数据对象在备忘录应用中，通过分布式数据对象框架，当用户在某一端设备上新增备忘录事件，修改编辑事件标题和内容以及清空事件列表时，产生的数据变更结果均可以同步刷新显现在可信组网内其他设备上。
