Method Details

createTriple

org.apache.jena.graph.Triple createTriple(org.apache.jena.graph.Node subject,
 org.apache.jena.graph.Node predicate,
 org.apache.jena.graph.Node object)

createQuad

Quad createQuad(org.apache.jena.graph.Node graph,
 org.apache.jena.graph.Node subject,
 org.apache.jena.graph.Node predicate,
 org.apache.jena.graph.Node object)

createURI

org.apache.jena.graph.Node createURI(String uriStr)

createTypedLiteral

org.apache.jena.graph.Node createTypedLiteral(String lexical,
 org.apache.jena.datatypes.RDFDatatype datatype)

createLangLiteral

org.apache.jena.graph.Node createLangLiteral(String lexical,
 String langTag)

createLangDirLiteral

org.apache.jena.graph.Node createLangDirLiteral(String lexical,
 String langTag,
 String direction)

createStringLiteral

org.apache.jena.graph.Node createStringLiteral(String lexical)

createBlankNode

org.apache.jena.graph.Node createBlankNode()

Create a blank node which is completely new and used nowhere else.

createBlankNode

org.apache.jena.graph.Node createBlankNode(String label)

Create a blank node with the given string as internal system id

createBlankNode

org.apache.jena.graph.Node createBlankNode(long mostSigBits,
 long leastSigBits)

Create a blank with the internal system id taken from 128 bit number provided. This must be compatible with UUID so the variant and version bits must agree with RFC 4122.

• UUID
• RFC 4122: A Universally Unique IDentifier (UUID) URN Namespace

reset

void reset()

Reset any internal state that should not be carried across parse runs (e.g. blank node labels).
