Class Quad

java.lang.Object
  com.hp.hpl.jena.sparql.core.Quad

public class Quad
extends Object

Field Summary

static com.hp.hpl.jena.graph.Node	defaultGraphIRI Name of the default for explict use in GRAPH
static com.hp.hpl.jena.graph.Node	defaultGraphNodeGenerated Name of the default graph as used in quad form of algebra.
static com.hp.hpl.jena.graph.Node	tripleInQuad Name of the non-graph when a quad is really a triple - also parsing of triples formats (and the default graph when parsing N-Quads or TriG) Not for access to the default graph by name - use Quad.defaultGraphIRI.
static com.hp.hpl.jena.graph.Node	unionGraph Name of the merge of all named graphs (use this for the graph of all named graphs)

Constructor Summary

Quad(com.hp.hpl.jena.graph.Node g, com.hp.hpl.jena.graph.Node s, com.hp.hpl.jena.graph.Node p, com.hp.hpl.jena.graph.Node o)

Field Detail

defaultGraphNodeGenerated

public static final com.hp.hpl.jena.graph.Node defaultGraphNodeGenerated

Name of the default graph as used in quad form of algebra. Not for access to the default graph by name - use Quad.defaultGraphIRI.

defaultGraphIRI

public static final com.hp.hpl.jena.graph.Node defaultGraphIRI

Name of the default for explict use in GRAPH

tripleInQuad

public static final com.hp.hpl.jena.graph.Node tripleInQuad

Name of the non-graph when a quad is really a triple - also parsing of triples formats (and the default graph when parsing N-Quads or TriG) Not for access to the default graph by name - use Quad.defaultGraphIRI.

unionGraph

public static final com.hp.hpl.jena.graph.Node unionGraph

Name of the merge of all named graphs (use this for the graph of all named graphs)
