org.eclipse.persistence.mappings
Class ManyToOneMapping

java.lang.Object
org.eclipse.persistence.mappings.DatabaseMapping
org.eclipse.persistence.mappings.ForeignReferenceMapping
org.eclipse.persistence.mappings.ObjectReferenceMapping
org.eclipse.persistence.mappings.OneToOneMapping
org.eclipse.persistence.mappings.ManyToOneMapping

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, MapComponentMapping, MapKeyMapping, RelationalMapping

public class ManyToOneMapping

extends OneToOneMapping

Purpose: Define the relationship to be a ManyToOne. This is mainly functionally the same as OneToOneMapping.

Since:

EclipseLink 2.1
