Constructor Details

CriteriaLoader

public CriteriaLoader(OuterJoinLoadable persister,
                      SessionFactoryImplementor factory,
                      CriteriaImpl criteria,
                      String rootEntityName,
                      Map enabledFilters)
            throws HibernateException

Method Details

applyLocks

protected String applyLocks(String sqlSelectString,
                            Map lockModes,
                            Dialect dialect)
            throws QueryException
Append FOR UPDATE OF clause, if necessary. This empty superclass implementation merely returns its first argument.
Overrides:
applyLocks in interface Loader

getLockModes

protected LockMode[] getLockModes(Map lockModes)
What lock mode does this load entities with?
Overrides:
getLockModes in interface OuterJoinLoader
Parameters:
lockModes - a collection of lock modes specified dynamically via the Query interface

getQuerySpaces

public Set getQuerySpaces()

getResultColumnOrRow

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

getResultList

protected List getResultList(List results,
                             ResultTransformer resultTransformer)
Overrides:
getResultList in interface Loader

isSubselectLoadingEnabled

protected boolean isSubselectLoadingEnabled()
Overrides:
isSubselectLoadingEnabled in interface Loader

list

public List list(SessionImplementor session)
            throws HibernateException

scroll

public ScrollableResults scroll(SessionImplementor session,
                                ScrollMode scrollMode)
            throws HibernateException
