Direct Known Subclasses:

CollectionAttributeJoin, ListAttributeJoin, MapAttributeJoin, SetAttributeJoin

public abstract class PluralAttributeJoinSupport<O,C,E>
extends AbstractJoinImpl<O,E>
implements javax.persistence.criteria.PluralJoin<O,C,E>

Support for defining joins to plural attributes (JPA requires typing based on the specific collection type so we cannot really implement all support in a single class)
