Interface JoinImplementor<Z,X>

All Superinterfaces:

Expression<X>, ExpressionImplementor<X>, Fetch<Z,X>, FetchParent<Z,X>, From<Z,X>, FromImplementor<Z,X>, Join<Z,X>, Path<X>, PathImplementor<X>, PathSource<X>, Renderable, Selection<X>, SelectionImplementor<X>, TupleElement<X>, TupleElementImplementor<X>

All Known Subinterfaces:

CollectionJoinImplementor<Z,X>, ListJoinImplementor<Z,X>, MapJoinImplementor<Z,K,V>, SetJoinImplementor<Z,X>

All Known Implementing Classes:

AbstractJoinImpl, CollectionAttributeJoin, CollectionAttributeJoin.TreatedCollectionAttributeJoin, ListAttributeJoin, ListAttributeJoin.TreatedListAttributeJoin, MapAttributeJoin, MapAttributeJoin.TreatedMapAttributeJoin, PluralAttributeJoinSupport, SetAttributeJoin, SetAttributeJoin.TreatedSetAttributeJoin, SingularAttributeJoin, SingularAttributeJoin.TreatedSingularAttributeJoin

public interface JoinImplementor<Z,X>
extends Join<Z,X>, Fetch<Z,X>, FromImplementor<Z,X>

Consolidates the Join and Fetch hierarchies since that is how we implement them. This allows us to treat them polymorphically.

JoinImplementor<Z,X>	on(Expression<Boolean> restriction) Coordinate return type between Join.on(Expression) and Fetch#on(Expression)
JoinImplementor<Z,X>	on(Predicate... restrictions) Coordinate return type between Join.on(Predicate...) and Fetch#on(Predicate...)
<T extends X> JoinImplementor<Z,T>	treatAs(Class<T> treatAsType) Defines handling for the JPA 2.1 TREAT down-casting feature.

treatAs

<T extends X> JoinImplementor<Z,T> treatAs(Class<T> treatAsType)

Description copied from interface: PathImplementor

Defines handling for the JPA 2.1 TREAT down-casting feature.

Specified by:
