Class LocalCacheManager<EK,AK,ISK>

java.lang.Object

org.hibernate.ogm.datastore.ehcache.persistencestrategy.impl.LocalCacheManager<EK,AK,ISK>

Type Parameters:

EK - the entity cache key type

AK - the association cache key type

ISK - the identity source cache key type

Direct Known Subclasses:

OnePerKindCacheManager, PerTableCacheManager

public abstract class LocalCacheManager<EK,AK,ISK>
extends Object

Provides access to the Ehcache caches used for storing entities, associations and id sources. The number of caches used depends on the specific implementation of this contract.

Implementations need to make sure all needed caches are started before state transfer happens. This prevents this node to return undefined cache errors during replication when other nodes join this one.

Implementations must be thread-safe.
