public class OrderedKeyValueStoreManagerAdapter extends Object implements KeyColumnValueStoreManager
OrderedKeyValueStoreManager and exposes it as a KeyColumnValueStoreManager.
An optional mapping of key-length can be defined if it is known that the KeyColumnValueStore of a given
name has a static key length. See OrderedKeyValueStoreAdapter for more information.| Constructor and Description |
