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

    public interface ListJoin<Z,E>
extends PluralJoin<Z,List<E>,E>

        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:
        restrictions - zero or more restriction predicates
        Returns:
        the modified join object
        Since:

      • getModel

        ListAttribute<? super Z,E> getModel()
        Return the metamodel representation for the list attribute.
        Specified by:
        getModel in interface Path<E>
        Specified by:
        getModel in interface PluralJoin<Z,List<E>,E>
        Returns:
        metamodel type representing the List that is the target of the join

      • index

        Expression<Integer> index()
        Create an expression that corresponds to the index of the object in the referenced association or element collection. This method must only be invoked upon an object that represents an association or element collection for which an order column has been defined.
        Returns:
