public class CorrelatedTableGroup
extends AbstractTableGroup

A virtual TableReference for correlated roots. Table group joins are pushed into the from clause as roots and join predicates to the where clause.

Method Summary

Modifier and Type	Method	Description
void	addNestedTableGroupJoin(TableGroupJoin join)	A nested table group join is a join against a table group, that is ensured to be joined against the primary table reference and table reference joins in isolation, prior to doing other table group joins e.g.
void	addTableGroupJoin(TableGroupJoin join)
void	applyAffectedTableNames(Consumer<String> nameCollector)
TableGroup	findCompatibleJoinedGroup(TableGroupJoinProducer joinProducer, SqlAstJoinType requestedJoinType)
TableGroup	getCorrelatedTableGroup()
Consumer<Predicate>	getJoinPredicateConsumer()
TableReference	getPrimaryTableReference()
TableReference	getTableReference(NavigablePath navigablePath, String tableExpression, boolean resolve)	Returns the table reference for the table expression, or null if not found.
TableReference	getTableReference(NavigablePath navigablePath, ValuedModelPart modelPart, String tableExpression, boolean resolve)
List<TableReferenceJoin>	getTableReferenceJoins()
void	prependTableGroupJoin(NavigablePath navigablePath, TableGroupJoin join)	Adds the given table group join before a join as found via the given navigable path.

addTableGroupJoin

public void addTableGroupJoin(TableGroupJoin join)

Specified by:

addTableGroupJoin in interface TableGroup

Overrides:

addTableGroupJoin in class AbstractTableGroup

prependTableGroupJoin

public void prependTableGroupJoin(NavigablePath navigablePath,
                                  TableGroupJoin join)

Description copied from interface: TableGroup

Adds the given table group join before a join as found via the given navigable path.

Specified by:

prependTableGroupJoin in interface TableGroup

Overrides:

prependTableGroupJoin in class AbstractTableGroup

addNestedTableGroupJoin

public void addNestedTableGroupJoin(TableGroupJoin join)

Description copied from interface: TableGroup

A nested table group join is a join against a table group, that is ensured to be joined against the primary table reference and table reference joins in isolation, prior to doing other table group joins e.g. select * from entity1 e left join ( collection_table c1 join association a on a.id = c1.target_id ) on c1.entity_id = e.id and c1.key = 1 is modeled as TableGroup( primaryTableReference = TableReference(entity1, e), tableGroupJoins = [ TableGroupJoin( TableGroup( primaryTableReference = TableReference(collection_table, c1), nestedTableGroupJoins = [ TableGroupJoin( TableGroup( primaryTableReference = TableReference(association, a) ) ) ] ) ) ] ) This is necessary to correctly retain the cardinality of an HQL join like e.g. from Entity1 e left join e.collectionAssociation c on key(c) = 1
