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.
