public AbstractValueFactory()

Method Details

createBNode

public BNode createBNode()

Description copied from interface: ValueFactory

Creates a new bNode.

Specified by:

createBNode in interface ValueFactory

Returns:

An object representing the bNode.

createBNode

public BNode createBNode(String nodeID)

Description copied from interface: ValueFactory

Creates a new blank node with the given node identifier.

Specified by:

createBNode in interface ValueFactory

Parameters:

nodeID - The blank node identifier.

Returns:

An object representing the blank node.

createIRI

public IRI createIRI(String iri)

Description copied from interface: ValueFactory

Creates a new IRI from the supplied string-representation.

Specified by:

createIRI in interface ValueFactory

Parameters:

iri - A string-representation of a IRI.

Returns:

An object representing the IRI.

createIRI

public IRI createIRI(String namespace,
 String localName)

Description copied from interface: ValueFactory

Creates a new IRI from the supplied namespace and local name. Calling this method is funtionally equivalent to calling createIRI(namespace+localName), but allows the ValueFactory to reuse supplied namespace and local name strings whenever possible. Note that the values returned by IRI.getNamespace() and IRI.getLocalName() are not necessarily the same as the values that are supplied to this method.

Specified by:

createIRI in interface ValueFactory

Parameters:

namespace - The IRI's namespace.

localName - The IRI's local name.

createLiteral

public Literal createLiteral(String label)

Description copied from interface: ValueFactory

Creates a new literal with the supplied label. The return value of Literal.getDatatype() for the returned object must be xsd:string.

Specified by:

createLiteral in interface ValueFactory

Parameters:

label - The literal's label, must not be null.

datatype - The literal's datatype. If it is null, the datatype xsd:string will be assigned to this literal.

Returns:

A literal for the specified value and type.
