Class RDFLangString

java.lang.Object

org.apache.jena.datatypes.BaseDatatype

org.apache.jena.datatypes.xsd.impl.RDFLangString

All Implemented Interfaces:

RDFDatatype

public class RDFLangString
extends BaseDatatype
implements RDFDatatype

rdf:dirLangString - a literal with language and initial text direction.

This covers the unusual case of "foo"^^rdf:langString. When there is a language tag, there is a lexical form but it is in two parts lex@lang. This is not rdf:plainLiteral!
