Method Detail

literalValues

public static List<String> literalValues(org.apache.jena.graph.Node root,
                                         org.apache.jena.graph.Node[] props,
                                         org.apache.jena.graph.Graph g)

Scans the properties in props testing if root has a value for that property. For the first such property it returns a list of all the lexical forms of that property.

getPropertyValue

public static org.apache.jena.graph.Node getPropertyValue(org.apache.jena.graph.Node root,
                                                          org.apache.jena.graph.Node prop,
                                                          org.apache.jena.graph.Graph g)

Find the first value of the given property of the root node. Return null if there's no such property.

getLocalName

public static String getLocalName(org.apache.jena.graph.Node root)

Find the local name of the URI of a node. This is for labelling purposes rather than XML serialization so splits at last # or /, may not return an NC name
