Package org.hibernate.metamodel.mapping.ordering.ast

Class ColumnReference

java.lang.Object

org.hibernate.metamodel.mapping.ordering.ast.ColumnReference

All Implemented Interfaces:

Node, OrderingExpression, SequencePart

public class ColumnReference
extends Object
implements OrderingExpression, SequencePart

Represents a column-reference used in an order-by fragment

API Note:

This is Hibernate-specific feature. For OrderBy (JPA) all path references are expected to be domain paths (attributes).
