```
- Method Detail
  - 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
    
    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 interface KeyStrategy
    
    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:
