Uses of Join in javax.persistence.criteria

Subinterfaces of Join in javax.persistence.criteria

Modifier and Type	Interface and Description
interface	CollectionJoin<Z,E> The CollectionJoin 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.Collection.
interface	ListJoin<Z,E> The ListJoin 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.List.
interface	MapJoin<Z,K,V> The MapJoin 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.Map.
interface	PluralJoin<Z,C,E> The PluralJoin interface defines functionality that is common to joins to all collection types.
interface	SetJoin<Z,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.

Methods in javax.persistence.criteria that return Join

Modifier and Type	Method and Description
<X,Y> Join<X,Y>	Subquery.correlate(Join<X,Y> parentJoin) Create a subquery join object correlated to a join object of the enclosing query.
<Y> Join<X,Y>	From.join(SingularAttribute<? super X,Y> attribute) Create an inner join to the specified single-valued attribute.
<Y> Join<X,Y>	From.join(SingularAttribute<? super X,Y> attribute, JoinType jt) Create a join to the specified single-valued attribute using the given join type.
<X,Y> Join<X,Y>	From.join(String attributeName) Create an inner join to the specified attribute.
<X,Y> Join<X,Y>	From.join(String attributeName, JoinType jt) Create a join to the specified attribute using the given join type.
Join<Z,X>	Join.on(Expression<Boolean> restriction) Modify the join to restrict the result according to the specified ON condition.
Join<Z,X>	Join.on(Predicate... restrictions) Modify the join to restrict the result according to the specified ON condition.
<X,T,V extends T> Join<X,V>	CriteriaBuilder.treat(Join<X,T> join, Class<V> type) Downcast Join object to the specified type.

Methods in javax.persistence.criteria that return types with arguments of type Join

Modifier and Type	Method and Description
Set<Join<?,?>>	Subquery.getCorrelatedJoins() Return the correlated joins of the subquery.
Set<Join<X,?>>	From.getJoins() Return the joins that have been made from this bound type.

Methods in javax.persistence.criteria with parameters of type Join

Modifier and Type	Method and Description
<X,Y> Join<X,Y>	Subquery.correlate(Join<X,Y> parentJoin) Create a subquery join object correlated to a join object of the enclosing query.
<X,T,V extends T> Join<X,V>	CriteriaBuilder.treat(Join<X,T> join, Class<V> type) Downcast Join object to the specified type.

Uses of Join in org.hibernate.jpa.criteria.path

Classes in org.hibernate.jpa.criteria.path that implement Join

Modifier and Type	Class and Description
class	AbstractJoinImpl<Z,X> Convenience base class for various Join implementations.
class	CollectionAttributeJoin<O,E> Models a join based on a plural association attribute.
static class	CollectionAttributeJoin.TreatedCollectionAttributeJoin<O,T>
class	ListAttributeJoin<O,E> Models a join based on a list-style plural association attribute.
static class	ListAttributeJoin.TreatedListAttributeJoin<O,T>
class	MapAttributeJoin<O,K,V> Models a join based on a map-style plural association attribute.
