Vue d’ensemble des méthodes
Méthode | Explication |
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. |
Méthodes
clearcache ()
cloud_io = AIO(r"C:\data\datacloud.acs")
rcsfile = cloud_io.open(r'testfile.txt', 'r')
rcsfile.cloud.clearcache()
usebufferedreader ()
cloud_io = AIO(r"C:\data\datacloud.acs")
rcsfile = cloud_io.open(r'testfile.txt', 'r')
rcsfile.cloud.usebufferedreader()
usecachedfile ({blocksize}, {cachesize})
Paramètre | Explication | Type de données |
blocksize | The block size. (La valeur par défaut est 32768) | Integer |
cachesize | The cache size. (La valeur par défaut est 0) | Integer |
cloud_io = AIO(r"C:\data\datacloud.acs")
rcsfile = cloud_io.open(r'testfile.txt', 'r')
