                   SessionImplementor session)
            throws HibernateException

Description copied from interface: UniqueEntityLoader

Load an entity instance. If optionalObject is supplied, load the entity state into the given (uninitialized) object.

Specified by:

load in interface UniqueEntityLoader

Throws:

HibernateException
