getInstance

public static ValueFactoryImpl getInstance()

createURI

public URI createURI(String uri)

Description copied from interface: ValueFactory

Creates a new URI from the supplied string-representation.

Parameters:

uri - A string-representation of a URI.

Returns:

An object representing the URI.

createURI

public URI createURI(String namespace,
                     String localName)

Description copied from interface: ValueFactory

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

Parameters:

namespace - The URI's namespace.

localName - The URI's local name.

createBNode

public BNode createBNode(String nodeID)

Description copied from interface: ValueFactory

Creates a new blank node with the given node identifier.

Parameters:

nodeID - The blank node identifier.

Returns:

An object representing the blank node.

createLiteral

public Literal createLiteral(String value)

Description copied from interface: ValueFactory

Creates a new literal with the supplied label.

Parameters:

value - The literal's label.

createLiteral

public Literal createLiteral(String value,
                             String language)

Description copied from interface: ValueFactory

Creates a new literal with the supplied label and language attribute.

Parameters:

value - The literal's label.

language - The literal's language attribute, or null if the literal doesn't have a language.

createLiteral

public Literal createLiteral(String value,
                             URI datatype)

Description copied from interface: ValueFactory

Creates a new literal with the supplied label and datatype.

Parameters:

value - The literal's label.

datatype - The literal's datatype, or null if the literal doesn't have a datatype.

createStatement

public Statement createStatement(Resource subject,
                                 URI predicate,
                                 Value object)

Description copied from interface: ValueFactory

Creates a new statement with the supplied subject, predicate and object.

Parameters:

                                 Resource context)
