public KeyStrategyManaged(KeyStrategy strategy)

Method Details

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 interface KeyStrategy

getDigestFromKey

public String getDigestFromKey(String key)

Description copied from interface: KeyStrategy

Specified by:

getDigestFromKey in interface KeyStrategy

Parameters:

key - the key

Returns:

a digest, or null

Description copied from interface: KeyStrategy

Gets the write context for the given blob.

Specified by:

getBlobWriteContext in interface KeyStrategy

equals
