Package cz.cvut.kbss.jopa.model.annotations

Annotation Interface EntityResult

@Target({})
@Retention(RUNTIME)
public @interface EntityResult

Used in conjunction with the SparqlResultSetMapping annotation to map the SELECT clause of a SPARQL query to an entity result.

If this annotation is used, the SPARQL statement should select all of the variables that are mapped to the entity object. This should include attributes of related entities. The results obtained when insufficient data is available are undefined.

Example:

     
 Query q = em.createNativeQuery(
 "SELECT ?uri, ?quantity, ?item, ?label, ?description "+
 "WHERE {
     ?uri a <http://onto.fel.cvut.cz/ontologies/jopa/Order> ;
        <http://onto.fel.cvut.cz/ontologies/ufo/has_part> ?item .
     ?item a <http://onto.fel.cvut.cz/ontologies/jopa/Order> ;
           rdfs:label ?label;
           rdfs:comment ?description .
 }", "OrderItemResults");
 @SparqlResultSetMapping(name="OrderItemResults",
 entities={
 @EntityResult(entityClass=cz.cvut.kbss.jopa.Order.class),
 @EntityResult(entityClass=cz.cvut.kbss.jopa.Item.class)
 })
