public class JCacheStore<K,T extends org.apache.gora.persistency.impl.PersistentBase>
extends org.apache.gora.store.impl.DataStoreBase<K,T>

JCacheStore is the primary class responsible for GORA CRUD operations on Hazelcast Caches. This class can be think of as caching layer that can is wrapped over any persistency dataStore implementations which extends DataStore. This class delegates most operations to it s persistency dataStore. Hazelcast cache implementation is based on JCache JSR 107 specification.
