is used, it is expected
that implementations of EntityPersister define a constructor accepting the following arguments:PersistentClass
- describes the metadata about the entity
to be handled by the persister
EntityRegionAccessStrategy
- the second level caching strategy for this entity

- the second level caching strategy for the natural-id
defined for this entity, if one
PersisterCreationContext
- access to additional
information useful while constructing the persister.
