T |
getReference(Object naturalIdValue)
Return the persistent instance with the given natural id value, assuming that the instance exists.

Return the persistent instance with the given natural id value, or
null if there is no such persistent
instance. |
SimpleNaturalIdLoadAccess<T> |
setSynchronizationEnabled(boolean enabled)
For entities with mutable natural ids, should Hibernate perform "synchronization" prior to performing
lookups? The default is to perform "synchronization" (for correctness).

SimpleNaturalIdLoadAccess<T> |
with(LockOptions lockOptions)
Specify the
LockOptions to use when retrieving the entity. |

actual error.naturalIdValue

if there is no such persistent
instance. If the instance is already associated with the session, return that instance, initializing it if
needed. This method never returns an uninitialized instance.naturalIdValue
