* @ProjectName: MiNote
|

* @Package: net.micode.notes.gtask.data
|
|
|
* @ClassName: Node
|
|
|
* @Description: 同步操作的基础数据类型，定义了相关指示同步操作的常量.该类包含以下属性：
|
|
|
* mGid：表示同步对象在云端服务器上的唯一标识符。
|
|
|
* mName：表示同步对象的名称。
|
|
|
* mLastModified：表示同步对象的最后修改时间。
|
|
|
* mDeleted：表示同步对象是否被删除。
|
|
|
* 该类提供了一些方法来操作同步对象：
|
|
|
* getCreateAction(int actionId)：根据指定的同步操作 ID（actionId）返回创建同步操作的 JSON 数据。
|
|
|
* getUpdateAction(int actionId)：根据指定的同步操作 ID（actionId）返回更新同步操作的 JSON 数据。
|
|
|
* setContentByRemoteJSON(JSONObject js)：从远程同步数据（js）中设置同步对象的内容。
|
|
|
* setContentByLocalJSON(JSONObject js)：从本地同步数据（js）中设置同步对象的内容。
|
|
|
* getLocalJSONFromContent()：将同步对象的内容转换为本地同步数据的 JSON 格式。
|
|
|
* getSyncAction(Cursor c)：根据同步对象在本地的状态（Cursor c），返回同步操作的 ID。
|
|
|
* 此外，该类还提供了一些 getter 和 setter 方法，用于访问同步对象的属性。
|
|
|
* 该类是一个抽象类，需要子类实现其中的抽象方法来完成特定同步对象的同步操作。
