Method Detail

asTypedValue

public static org.apache.jena.rdf.model.RDFNode asTypedValue(String value)

Return a typed RDFNode based on a guess of the type from the syntax. Handles numbers, date/dateTimes and URIs. Defaults to a plain literal.

asTypedValue

public static org.apache.jena.rdf.model.RDFNode asTypedValue(String value,
                                                             String typeURI,
                                                             String lang)

Return a typed RDFNode using the given type URI. If the type URI is null then the typed is guessed, if it is empty string then a plain literal is used, if it is rdfs:Resource then a returns a resource.

asTypedValue

public static org.apache.jena.rdf.model.RDFNode asTypedValue(String value,
                                                             String typeURI)

Return a typed RDFNode using the given type URI. If the type URI is null then the typed is guessed, if it is empty string then a plain literal is used, if it is rdfs:Resource then a returns a resource.
