K - the key typeV - the value typepublic interface CachingTier<K,V> extends ConfigurationChangeSupport
AuthoritativeTier.
 
 As soon as there is more than one tier in a Store, one will be the AuthoritativeTier while others
 will be regrouped under the CachingTier

| void | invalidateAllWithHash(long hash)Remove all mappings whose key have the specified hash code from the  CachingTier, triggering theCachingTier.InvalidationListenerif registered. | 
| void | setInvalidationListener(CachingTier.InvalidationListener<K,V> invalidationListener)Set the caching tier's  CachingTier.InvalidationListener. |
