Example 21 with Node

use of org.apache.jena.graph.Node in project jena by apache.

the class T_TransSystem method genQuad.

static Quad genQuad(int value) {
    Node g1 = q.getGraph();
    int n1 = (int) Math.round(Math.random() * 10000);
    int n2 = (int) Math.round(Math.random() * 10000);
    // urn:x-arq:DefaultGraphNode
    Node g = Quad.defaultGraphNodeGenerated;
    Node s = NodeFactory.createURI("S");
    Node p = NodeFactory.createURI("P" + value);
    // Integer - that gets inlined.
    Node o = NodeFactory.createLiteral(Integer.toString(value), XSDDatatype.XSDinteger);
    return new Quad(g, s, p, o);
}
