-----------------------------------
Summary: Seq "set" and "add" methods yield different results.
Key: JENA-2075
URL: https://issues.apache.org/jira/browse/JENA-2075
Project: Apache Jena
Issue Type: Bug
Components: Core
Affects Versions: Jena 3.17.0
Reporter: Claude Warren
I think the issue is in the Seq.set() method but the if the example below is
executed the results are variously boolean values or strings representing
boolean values.
Code:
{code:java}
import org.apache.jena.rdf.model.Model;
import org.apache.jena.rdf.model.ModelFactory;
import org.apache.jena.rdf.model.Seq;
public class SeqTest {
public static void main(String[] args) {
Model m = ModelFactory.createDefaultModel();
Seq seq = m.createSeq();
seq.add( 1L );
seq.add(2, 2L );
m.write(System.out, "TURTLE");
seq.set(1, 1L);
m.write(System.out, "TURTLE");
}
}
{code}
Result:
{code:java}
[ a <http://www.w3.org/1999/02/22-rdf-syntax-ns#Seq> ;
<http://www.w3.org/1999/02/22-rdf-syntax-ns#_1>
"1" ;
<http://www.w3.org/1999/02/22-rdf-syntax-ns#_2>
"2"
] .
[ a <http://www.w3.org/1999/02/22-rdf-syntax-ns#Seq> ;
<http://www.w3.org/1999/02/22-rdf-syntax-ns#_1>
"1"^^<http://www.w3.org/2001/XMLSchema#long> ;
<http://www.w3.org/1999/02/22-rdf-syntax-ns#_2>
"2"
] .
{code}
The Collection.add() code and the Seq.add() methods both insert string
representations for the long values. The Seq.set() method on the other hand
places a typed literal in the graph.
Personally I would rather see the typed literal but I don't know that the
standard says.
