Constructor Detail

AbstractEntityLoader

public AbstractEntityLoader(OuterJoinLoadable persister,
                    Type uniqueKeyType,
                    SessionFactoryImplementor factory,
                    LoadQueryInfluencers loadQueryInfluencers)

Method Detail

load

public Object load(Serializable id,
          Object optionalObject,
          SessionImplementor session)

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

Specified by:

load in interface UniqueEntityLoader

load

public Object load(Serializable id,
          Object optionalObject,
          SessionImplementor session,
          LockOptions lockOptions)

Load an entity instance by id. If optionalObject is supplied (non-null, the entity state is loaded into that object instance instead of instantiating a new one.

Specified by:

load in interface UniqueEntityLoader

Parameters:

id - The id to be loaded

optionalObject - The (optional) entity instance in to which to load the state

session - The session from which the request originated

lockOptions - The lock options.

Returns:

The loaded entity

load

          Object id,
          Object optionalObject,
          Serializable optionalId,

getResultColumnOrRow

protected Object getResultColumnOrRow(Object[] row,
                          ResultTransformer transformer,
                          ResultSet rs,
                          SessionImplementor session)
                               throws SQLException,
                                      HibernateException

Description copied from class: Loader

Get the actual object that is returned in the user-visible result list. This empty implementation merely returns its first argument. This is overridden by some subclasses.

Overrides:

getResultColumnOrRow in class Loader

Throws:

SQLException

HibernateException

isSingleRowLoader

protected boolean isSingleRowLoader()

Description copied from class: Loader

Return false is this loader is a batch entity loader

Overrides:

isSingleRowLoader in class Loader
