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

Class SingularQueryAttributeImpl<X,Y>

java.lang.Object

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

cz.cvut.kbss.jopa.model.metamodel.SingularQueryAttributeImpl<X,Y>

Type Parameters:

X - The represented type that contains the attribute

Y - The type of the represented attribute

All Implemented Interfaces:

FieldSpecification<X,Y>, QueryAttribute<X,Y>, SingularQueryAttribute<X,Y>

public class SingularQueryAttributeImpl<X,Y>
extends AbstractQueryAttribute<X,Y>
implements SingularQueryAttribute<X,Y>

Singular query attributes contain a single value or reference, ie. they are not collections.
