org.gridgain.grid.cache.hibernate.GridHibernateRegion

org.gridgain.grid.cache.hibernate.GridHibernateTransactionalDataRegion

org.gridgain.grid.cache.hibernate.GridHibernateNaturalIdRegion

All Implemented Interfaces:

org.hibernate.cache.spi.NaturalIdRegion, org.hibernate.cache.spi.Region, org.hibernate.cache.spi.TransactionalDataRegion

public class GridHibernateNaturalIdRegion
extends GridHibernateTransactionalDataRegion
implements org.hibernate.cache.spi.NaturalIdRegion

Implementation of NaturalIdRegion. This region is used to store naturalId data.

L2 cache for entity naturalId and target cache region can be set using annotations:

 @javax.persistence.Entity
 @javax.persistence.Cacheable
 @org.hibernate.annotations.Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
 @org.hibernate.annotations.NaturalIdCache
 public class Entity {
     @org.hibernate.annotations.NaturalId
     private String entityCode;

     ...
 }
