Constructor Detail

AliasResolutionContextImpl

public AliasResolutionContextImpl(SessionFactoryImplementor sessionFactory)

Constructs a AliasResolutionContextImpl without any source aliases. This form is used in non-query (HQL, criteria, etc) contexts.

Parameters:

sessionFactory - The session factory

AliasResolutionContextImpl

public AliasResolutionContextImpl(SessionFactoryImplementor sessionFactory,
                          int suffixSeed)

Constructs a AliasResolutionContextImpl without any source aliases. This form is used in non-query (HQL, criteria, etc) contexts.

See the notes on org.hibernate.loader.plan2.exec.spi.AliasResolutionContext#getSourceAlias for discussion of "source aliases". They are not implemented here yet.

Parameters:

sessionFactory - The session factory

suffixSeed - The seed value to use for generating the suffix used when generating SQL aliases.

generateEntityReferenceAliases

public EntityReferenceAliases generateEntityReferenceAliases(String uid,
                                                    EntityPersister entityPersister)

generateCollectionReferenceAliases

public CollectionReferenceAliases generateCollectionReferenceAliases(String uid,
                                                            CollectionPersister persister)

registerQuerySpaceAliases

public void registerQuerySpaceAliases(String querySpaceUid,
                             EntityReferenceAliases entityReferenceAliases)

registerSqlTableAliasMapping

public void registerSqlTableAliasMapping(String querySpaceUid,
                                String sqlTableAlias)

resolveSqlTableAliasFromQuerySpaceUid

public String resolveSqlTableAliasFromQuerySpaceUid(String querySpaceUid)

Specified by:

resolveSqlTableAliasFromQuerySpaceUid in interface AliasResolutionContext

resolveEntityReferenceAliases

public EntityReferenceAliases resolveEntityReferenceAliases(String querySpaceUid)

Description copied from interface: AliasResolutionContext

Resolve the given QuerySpace UID to the EntityReferenceAliases representing the SQL aliases used in building the SQL query.

Assumes that a QuerySpace has already been registered. As such this method simply returns null if no QuerySpace with that UID has yet been resolved in the context.

Specified by:

resolveEntityReferenceAliases in interface AliasResolutionContext

Parameters:

querySpaceUid - The QuerySpace UID whose EntityReferenceAliases we want to look up.

Returns:

The corresponding QuerySpace UID, or null.

registerQuerySpaceAliases

public void registerQuerySpaceAliases(String querySpaceUid,
                             CollectionReferenceAliases collectionReferenceAliases)

resolveCollectionReferenceAliases

public CollectionReferenceAliases resolveCollectionReferenceAliases(String querySpaceUid)

Description copied from interface: AliasResolutionContext

Resolve the given QuerySpace UID to the CollectionReferenceAliases representing the SQL aliases used in building the SQL query.

Assumes that a QuerySpace has already been registered. As such this method simply returns null if no QuerySpace with that UID has yet been resolved in the context.

Specified by:

resolveCollectionReferenceAliases in interface AliasResolutionContext

Parameters:

querySpaceUid - The QuerySpace UID whose CollectionReferenceAliases we want to look up.

Returns:

The corresponding QuerySpace UID, or null.

registerCompositeQuerySpaceUidResolution

public void registerCompositeQuerySpaceUidResolution(String rightHandSideUid,
                                            String leftHandSideTableAlias)

dumpResolutions

public void dumpResolutions(LoadPlan loadPlan)

USes its defined logger to generate a resolution report.

Parameters:

loadPlan - The loadplan that was processed.
