サマリー
Performs file related operations that are cloud specific.
説明
This class cannot be instantiated directly. An instance of this class is returned by the AIOFile object's cloud property.
方法の概要
| 方法 | 説明 |
| clearcache () | Clears file properties and BLOB region cache. Call this method when an external process updates the file. |
| usebufferedreader () | Caches last read bytes. |
| usecachedfile ({blocksize}, {cachesize}) |
Uses least recently used (LRU) block cache for handling files on cloud. |
方法
