Method Detail

createNonNegativeInteger

public static org.apache.jena.graph.Node createNonNegativeInteger(String s)

Create an xsd:nonNegativeInteger literal from a string. Useful when parsing number restrictions.

Parameters:

s - A String of the number to be parsed

Returns:

A literal Node

isOWL2Datatype

public static boolean isOWL2Datatype(org.apache.jena.graph.Node n)

Test if a Node is an OWL 2 datatype.

Parameters:

n - The Node to test

Returns:

true if n matches the URI of an OWL 2 datatype, else false

listToTriples

public static org.apache.jena.graph.Node listToTriples(List<org.apache.jena.graph.Node> nodes,
                                                       Collection<org.apache.jena.graph.Triple> triples)

Construct an RDF container from a List of nodes, preserving the ordering

Parameters:

nodes - The list of Nodes

triples - A mutable container to which the Triples representing the container will be added.

Returns:

The blank node used as the start of the container
