public class OrderedManyToManyMapping

extends ManyToManyMapping

implements Ordered

Represents an ordered M-M mapping with a persistent object type. Ordered M-M mappings are stored in a separate table from the primary values of the owning class. Each row of the table holds three values: a single PK value of the related object collection in the data column, the PK value of the owning object in the ref column, and the order of the value in the order column. All ordered M-M mappings are one-sided.
