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)
void	applySqlSelections(DomainResultCreationState creationState)	Used when this producer is a selection in a sub-query.
boolean	canUseInnerJoins()
DomainResult	createDomainResult(String resultVariable, DomainResultCreationState creationState)	Produce the domain query
TableGroup	getElementTableGroup()
PluralAttributeMapping	getExpressionType()	The type for this expression
String	getGroupAlias()	If we want to use CTE for TableGroup rendering we will need to know the alias we can use for the group
TableGroup	getIndexTableGroup()
PluralAttributeMapping	getModelPart()
NavigablePath	getNavigablePath()
List<TableGroupJoin>	getNestedTableGroupJoins()
TableReference	getPrimaryTableReference()
protected SessionFactoryImplementor	getSessionFactory()
String	getSourceAlias()

TableReference	getTableReference(NavigablePath navigablePath, String tableExpression, boolean resolve)	Returns the table reference for the table expression, or null if not found.
List<TableReferenceJoin>	getTableReferenceJoins()
boolean	isFetched()
boolean	isRealTableGroup()
void	prependTableGroupJoin(NavigablePath navigablePath, TableGroupJoin join)	Adds the given table group join before a join as found via the given navigable path.

public void addTableGroupJoin(TableGroupJoin join)

Specified by:

public void prependTableGroupJoin(NavigablePath navigablePath,
                                  TableGroupJoin join)

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

applySqlSelections

public void applySqlSelections(DomainResultCreationState creationState)
