getLabel
public java.lang.String getLabel()
Description copied from interface:Literal
Gets the label (the lexical value) of this literal.- Returns:
- The literal's label.
-
getLanguage
public java.util.Optional<java.lang.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 returnrdf:langString
. If no datatype was assigned to this literal by the creator, then this method must returnxsd:string
.- Returns:
- The datatype for this literal.
-
temporalAccessorValue
public java.time.temporal.TemporalAccessor temporalAccessorValue()
Description copied from interface:Literal
Retrieves thetemporal accessor
value of this literal.A temporal accessor representation can be given for literals whose label conforms to the syntax of the following XML Schema 1.1 date/time datatypes:
Temporal accessor representations may be converted to specific
java.time
values likeOffsetDateTime
using target static factory methods, for instanceOffsetDateTime.from(literal.temporalAccessorValue())
.Note however that
java.time
doesn't include dedicated classes for some legal XML Schema date/time values, like offset dates (for instance,2020-11-16+01:00
) andxsd:gDay
(for instance,---16
).- Specified by:
temporalAccessorValue
in interfaceLiteral
- Overrides:
temporalAccessorValue
in classAbstractLiteral
- Returns:
- the temporal accessor value of this literal

getCoreDatatype
public CoreDatatype 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 {@link CoreDatatype#NONE)} is used to represent a datatype that is not one of the supported core datatypes.- Returns:
- The CoreDatatype or {@link CoreDatatype#NONE)} if the datatype matches none of the core datatypes. This method will not return null.
