Class ManyToOneMapping

java.lang.Object

org.eclipse.persistence.core.mappings.CoreMapping<AttributeAccessor,AbstractSession,ContainerPolicy,ClassDescriptor,DatabaseField>

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:

Serializable, 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
