Class ManyToOneMapping

java.lang.Object

org.eclipse.persistence.core.mappings.CoreMapping<AttributeAccessor,org.eclipse.persistence.internal.sessions.AbstractSession,org.eclipse.persistence.internal.queries.ContainerPolicy,ClassDescriptor,org.eclipse.persistence.internal.helper.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.
