方法详细资料

getInstance

public static SyncFileManager getInstance()

getCurrentLocalFiles

public void getCurrentLocalFiles(String dataDir)

从接口复制的说明: ISyncFileManager

Find out all closed and unmodified files, which means there has a .resource file and doesn't have a .mod file and .merge file. For these files, they will eventually generate a new tsfile file as the merge operation is executed and executed in subsequent synchronization tasks.

指定者:

getCurrentLocalFiles 在接口中 ISyncFileManager

参数:

dataDir - data directory

getLastLocalFiles

public void getLastLocalFiles(File lastLocalFileInfo)
                       throws IOException

从接口复制的说明: ISyncFileManager

Load last local files from file which does not contain those tsfiles which are not synced successfully in previous sync tasks.

指定者:

getLastLocalFiles 在接口中 ISyncFileManager

参数:

lastLocalFileInfo - last local file, which may not exist in first sync task.

抛出:

IOException

getValidFiles

public void getValidFiles(String dataDir)
                   throws IOException

从接口复制的说明: ISyncFileManager

Based on current local files and last local files, we can distinguish two kinds of files between them, one is deleted files, the other is new files. These two kinds of files are valid files that need to be synchronized to the receiving end.

指定者:

getValidFiles 在接口中 ISyncFileManager

参数:

dataDir - data directory

抛出:

IOException

getCurrentSealedLocalFilesMap

public Map<String,Map<Long,Map<Long,Set<File>>>> getCurrentSealedLocalFilesMap()

指定者:

getCurrentSealedLocalFilesMap 在接口中 ISyncFileManager

getLastLocalFilesMap

public Map<String,Map<Long,Map<Long,Set<File>>>> getLastLocalFilesMap()

指定者:

getLastLocalFilesMap 在接口中 ISyncFileManager

getDeletedFilesMap

public Map<String,Map<Long,Map<Long,Set<File>>>> getDeletedFilesMap()

指定者:

getDeletedFilesMap 在接口中 ISyncFileManager

getToBeSyncedFilesMap

public Map<String,Map<Long,Map<Long,Set<File>>>> getToBeSyncedFilesMap()

指定者:

getToBeSyncedFilesMap 在接口中 ISyncFileManager

getAllSGs

public Map<String,Map<Long,Set<Long>>> getAllSGs()

指定者:

getAllSGs 在接口中 ISyncFileManager
