Package cz.cvut.kbss.jopa.model.metamodel

Class PluralQueryAttributeImpl<X,C,E>

java.lang.Object

cz.cvut.kbss.jopa.model.metamodel.AbstractQueryAttribute<X,C>

cz.cvut.kbss.jopa.model.metamodel.PluralQueryAttributeImpl<X,C,E>

Type Parameters:

X - The represented type that contains the attribute

C - The type of the collection

E - The type of the element inside the collection

All Implemented Interfaces:

Bindable<E>, FieldSpecification<X,C>, PluralQueryAttribute<X,C,E>, QueryAttribute<X,C>

public class PluralQueryAttributeImpl<X,C,E>
extends AbstractQueryAttribute<X,C>
implements PluralQueryAttribute<X,C,E>

Plural query attributes can contain multiple values or references, i.e., they must be a collection.
