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)
boolean	canUseInnerJoins()
ModelPart	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
ModelPartContainer	getModelPart()
NavigablePath	getNavigablePath()
List<TableGroupJoin>	getNestedTableGroupJoins()
protected SessionFactoryImplementor	getSessionFactory()
String	getSourceAlias()
SqlAliasBase	getSqlAliasBase()
List<TableGroupJoin>	getTableGroupJoins()
boolean	isRealTableGroup()
void	prependTableGroupJoin(NavigablePath navigablePath, TableGroupJoin join)	Adds the given table group join before a join as found via the given navigable path.
void	removeTableGroupJoin(TableGroupJoin join)	Removes the given table group join from this group's joins.

public void prependTableGroupJoin(NavigablePath navigablePath,
 TableGroupJoin join)

Description copied from interface: TableGroup

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
