useDeDuplication
public boolean useDeDuplication()
Description copied from interface:KeyStrategy
Checks whether this key strategy uses de-duplication. When de-duplication is used, two blobs with identical contents have identical keys.- Specified by:
useDeDuplication
in interfaceKeyStrategy
-
getDigestFromKey
public String getDigestFromKey(String key)
Description copied from interface:KeyStrategy
Gets, if possible, a digest from the key. This is not possible if the key is not derived from a digest.- Specified by:
getDigestFromKey
in interfaceKeyStrategy
- Parameters:
key
- the key- Returns:
- a digest, or
null
-
getBlobWriteContext
public BlobWriteContext getBlobWriteContext(BlobContext blobContext)
Description copied from interface:KeyStrategy
Gets the write context for the given blob.- Specified by:
