          org.eclipse.persistence.mappings.MultitenantPrimaryKeyMapping

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

public class MultitenantPrimaryKeyMapping
extends AbstractColumnMapping

Purpose: Maps a multitenant property to the corresponding database field type. The list of field types that are supported by EclipseLink's direct to field mapping is dependent on the relational database being used.
