TaggedLiteral(String label,
 String language)

Method Details

getLabel

public String getLabel()

Description copied from interface: Literal

Gets the label (the lexical value) of this literal.

Returns:

The literal's label.

getLanguage

public Optional<String> getLanguage()

Description copied from interface: Literal

Gets the language tag for this literal, normalized to lower case.

Returns:

The language tag for this literal, or Optional.empty() if it doesn't have one.

getDatatype

public IRI getDatatype()

Description copied from interface: Literal

Gets the datatype for this literal.

If Literal.getLanguage() returns a non-empty value than this must return rdf:langString. If no datatype was assigned to this literal by the creator, then this method must return xsd:string.

Returns:

The datatype for this literal.

getCoreDatatype

public CoreDatatype.RDF 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 constant

invalid @link

{@link CoreDatatype#NONE)

} is used to represent a datatype that is not one of the supported core datatypes.

Returns:

The CoreDatatype or

invalid @link

{@link CoreDatatype#NONE)

} if the datatype matches none of the core datatypes. This method will not return null.
