Method Detail

createTriple

Triple createTriple(Node subject,
                    Node predicate,
                    Node object)

createQuad

Quad createQuad(Node graph,
                Node subject,
                Node predicate,
                Node object)

createURI

Node createURI(java.lang.String uriStr)

createTypedLiteral

Node createTypedLiteral(java.lang.String lexical,
                        RDFDatatype datatype)

createLangLiteral

Node createLangLiteral(java.lang.String lexical,
                       java.lang.String langTag)

createStringLiteral

Node createStringLiteral(java.lang.String lexical)

createBlankNode

Node createBlankNode()

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

createBlankNode

Node createBlankNode(java.lang.String label)

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

createBlankNode

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).
