public void
addNestedTableGroupJoin(TableGroupJoin join)

Overrides org.hibernate.sql.ast.tree.from.AbstractTableGroup.addNestedTableGroupJoin.

Implements org.hibernate.sql.ast.tree.from.TableGroup.addNestedTableGroupJoin.

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
