getCoreDatatype
Description copied from interface:Literal
CoreDatatype is an interface for natively supported datatypes in RDF4J. This includes, among others, the XML Schema datatypes and rdf:langString. CoreDatatypes are implemented as enums and more performant and convenient to work with than IRI-based datatypes. The constantinvalid @link
{@link CoreDatatype#NONE)
- Returns:
- The CoreDatatype or
invalid @link
{@link CoreDatatype#NONE)
