* @功能描述:初始化GTask列表的方法。通过与GTask服务器进行通信,获取任务列表和任务数据,并将其存储在相应的数据结构中。
|
|
|
|
|
|
|
|
* @实现过程:
|
|
|
|
|
|
|
|
*首先,代码从GTaskClient实例中获取任务列表的JSON对象数组。然后,它遍历这个数组,逐个解析每个JSON对象。对于元表(名字以特定前缀开头),代码创建一个TaskList对象,并将其内容从远程JSON对象复制到该对象中。然后,它获取该元表下的任务列表的JSON对象数组,并遍历这个数组。对于每个任务,代码创建一个MetaData对象,并将其内容从远程JSON对象复制到该对象中。如果该任务值得保存(由isWorthSaving()方法决定),则将其添加到元表的子任务列表中,并将其相关的gid作为键,将MetaData对象添加到mMetaHashMap中。
|
|
|
|
|
|
|
|
* 如果元表不存在,则代码创建一个新的元表,并使用GTaskClient实例的createTaskList方法将其发送到服务器。
|
|
|
|
|
|
|
|
* 接下来,代码再次遍历任务列表的JSON对象数组。对于以特定前缀开头但不是元表的任务列表,代码创建一个TaskList对象,并将其内容从远程JSON对象复制到该对象中。然后,它获取该任务列表下的任务的JSON对象数组,并遍历这个数组。对于每个任务,代码创建一个Task对象,并将其内容从远程JSON对象复制到该对象中。如果该任务值得保存,代码将其关联的元数据设置为mMetaHashMap中对应的对象,并将该任务添加到任务列表的子任务列表中,并使用gid作为键,将Task对象添加到mGTaskHashMap中。
|
|
|
|
|
|
|
|
* 最后,如果出现JSON解析异常,代码会打印错误信息并抛出ActionFailureException异常。

|

|
|
|
|
|
|
|
* 接下来,代码查询本地数据库中的已删除笔记,并遍历结果集。对于每个已删除笔记,代码从mGTaskHashMap中根据gid获取对应的Node对象。如果存在该Node对象,说明该笔记在服务器上也存在,需要进行远程删除操作。代码将该Node对象从mGTaskHashMap中移除,并调用doContentSync方法执行同步操作。同时,将该笔记的ID添加到mLocalDeleteIdMap中。
|
|
|
|
|
|
|
|
* 然后,代码调用syncFolder方法同步文件夹信息。
|
|
|
|
|
|
|
|
* 接下来,代码查询本地数据库中的已存在的笔记,并遍历结果集。对于每个已存在的笔记,代码从mGTaskHashMap中根据gid获取对应的Node对象。如果存在该Node对象,说明该笔记在服务器上也存在,需要根据Node对象的同步状态执行相应的同步操作。如果不存在该Node对象,说明该笔记在服务器上不存在,需要执行本地添加操作或远程删除操作。
|
|
|
|
|
|
|
|
* 最后,代码使用Iterator迭代器遍历mGTaskHashMap中剩余的未处理的Node对象,并执行本地添加操作。
|
|
|
|
|
|
|
|
* 在整个同步过程中,代码会检查mCancelled变量是否被设置为true,如果是,则立即返回并结束同步过程。
|
|
|
|
|
|
|
|
* 最后,代码会清空已删除的本地笔记,并更新本地同步ID,以及提交更新到GTask服务器。

|
|
|
|
|
|
|
|
* 如果节点不是 TaskList 类型,则创建一个普通 SqlNote,并将其内容设置为节点的本地 JSON 数据。同时,还需要设置该 SqlNote 的 parentId,即节点的父节点在本地 ContentProvider 中对应的 Id。
|
|
|
|
|
|
|
|
* 设置 SqlNote 的 GTaskId 为节点的 Gid,并将该 SqlNote 提交到本地 ContentProvider 中,创建一个本地节点。
|
|
|
|
|
|
|
|
* 更新 mGidToNid 和 mNidToGid,用于保存 GTask 中的 Gid 和本地 ContentProvider 中的 Id 之间的映射关系。
|
|
|
|
|
|
|
|
* 最后,通过 updateRemoteMeta 方法,将该节点的元数据保存到 MetaData 中,确保 GTask 和本地 ContentProvider 中的节点信息一致。

* @功能名:refreshLocalSyncId()
|
|
|
|
|
|
|
|
* @功能描述:刷新本地节点的同步ID
|
|
|
|
|
|
|
|
* @实现过程:
|
|
|
|
|
|
|
|
* 首先,判断是否已经取消同步(mCancelled),如果已经取消同步,则直接返回。
|
|
|
|
|
|
|
|
* 接着,清空 mGTaskHashMap、mGTaskListHashMap 和 mMetaHashMap,然后初始化 GTaskList。
|
|
|
|
|
|
|
|
* 接下来,使用 ContentResolver 的 query 方法查询本地笔记数据,通过 Notes.CONTENT_NOTE_URI 和 SqlNote.PROJECTION_NOTE 获取到需要更新的笔记列表。
|
|
|
|
|
|
|
|
* 如果查询结果不为 null,则遍历查询结果。对于每个查询结果,获取其对应的 gid,并从 mGTaskHashMap 中获取到对应的节点对象 node。
|
|
|
|
|
|
|
|
* 如果 node 不为 null,表示该节点在远程服务器上存在,需要更新同步ID。首先从 mGTaskHashMap 中移除该节点。然后,创建一个 ContentValues 对象 values,并将需要更新的同步ID存入其中。
|
|
|
|
|
|
|
|
* 接着,使用 ContentResolver 的 update 方法,通过 ContentUris.withAppendedId 将更新的内容应用到对应的本地笔记记录上。
|
|
|
|
|
|
|
|
* 如果 node 为 null,表示该本地笔记在远程服务器上没有对应的节点,抛出 ActionFailureException 异常。
|
|
|
|
|
|
|
|
* 最后,在 finally 块中关闭游标 c。
