Example 6 with LazyTableGroup

use of org.hibernate.sql.ast.tree.from.LazyTableGroup in project hibernate-orm by hibernate.

the class EntityCollectionPart method createTableGroupJoin.

@Override
public TableGroupJoin createTableGroupJoin(NavigablePath navigablePath, TableGroup collectionTableGroup, String explicitSourceAlias, SqlAstJoinType requestedJoinType, boolean fetched, boolean addsPredicate, SqlAliasBaseGenerator aliasBaseGenerator, SqlExpressionResolver sqlExpressionResolver, FromClauseAccess fromClauseAccess, SqlAstCreationContext creationContext) {

    }
    if (collectionDescriptor.isOneToMany() && nature == Nature.ELEMENT) {
        // If this is a one-to-many, the element part is already available, so we return a TableGroupJoin "hull"
        return new TableGroupJoin(navigablePath, joinType, ((OneToManyTableGroup) collectionTableGroup).getElementTableGroup(), null);
    }
    final LazyTableGroup lazyTableGroup = createRootTableGroupJoin(navigablePath, collectionTableGroup, explicitSourceAlias, requestedJoinType, fetched, null, aliasBaseGenerator, sqlExpressionResolver, fromClauseAccess, creationContext);
