target - Metadata object on which version might be applied

Returns:

either, the target Metadata instance as it was when it was called, or a brand new target Metadata instance with version from source metadata applied.

updateMetadata

public static void updateMetadata(CacheEntry entry,
                                  Metadata providedMetadata)

Set the providedMetadata on the cache entry. If the entry already has a version, copy the version in the new metadata.
