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)
boolean	canUseInnerJoins()
ModelPartContainer	getExpressionType()	The type for this expression
TableReference	getPrimaryTableReference()
String	getSourceAlias()
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()
TableGroup	getUnderlyingTableGroup()
boolean	isFetched()
void	prependTableGroupJoin(NavigablePath navigablePath, TableGroupJoin join)	Adds the given table group join before a join as found via the given navigable path.

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

Overrides:

addNestedTableGroupJoin in class AbstractTableGroup

getTableReference

public TableReference getTableReference(NavigablePath navigablePath,
                                        String tableExpression,
                                        boolean resolve)

getTableReference in interface ColumnReferenceQualifier

Overrides:

getTableReference in class AbstractColumnReferenceQualifier

Parameters:

navigablePath - The path for which to look up the table reference, may be null

tableExpression - The table expression for which to look up the table reference

resolve - Whether to potentially create table reference joins for this table group
