Interface SetJoin<Z,E>

Type Parameters:

Z - the source type of the join

E - the element type of the target Set

All Superinterfaces:

Expression<E>, FetchParent<Z,E>, From<Z,E>, Join<Z,E>, Path<E>, PluralJoin<Z,Set<E>,E>, Selection<E>, TupleElement<E>

All Known Subinterfaces:

SetJoinImplementor<Z,X>

All Known Implementing Classes:

SetAttributeJoin, SetAttributeJoin.TreatedSetAttributeJoin

public interface SetJoin<Z,E>
extends PluralJoin<Z,Set<E>,E>

The SetJoin interface is the type of the result of joining to a collection over an association or element collection that has been specified as a java.util.Set.

Since:

Java Persistence 2.0

on

SetJoin<Z,E> on(Expression<Boolean> restriction)

Modify the join to restrict the result according to the specified ON condition and return the join object. Replaces the previous ON condition, if any.

Specified by:

on in interface Join<Z,E>

Parameters:

restriction - a simple or compound boolean expression

Returns:

the modified join object

Since:

restrictions - zero or more restriction predicates

Returns:

the modified join object

Since:

getModel

SetAttribute<? super Z,E> getModel()

Return the metamodel representation for the set attribute.

Specified by:

getModel in interface Path<E>

Specified by:

getModel in interface PluralJoin<Z,Set<E>,E>

Returns:

metamodel type representing the Set that is the target of the join
