AbstractEntityLoader

public AbstractEntityLoader(OuterJoinLoadable persister,
                            Type uniqueKeyType,
                            SessionFactoryImplementor factory,

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

                      Object id,
                      Object optionalObject,
                      Serializable optionalId,

getResultColumnOrRow

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

                                      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
