Method Detail

parseTemporalAmount
static java.time.temporal.TemporalAmount parseTemporalAmount(java.lang.CharSequence label)
-
toString
private static java.lang.String toString(java.time.temporal.TemporalAmount value)
-
getLabel
public java.lang.String getLabel()
Description copied from interface:LiteralGets 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:LiteralGets 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:LiteralGets 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.
-
temporalAmountValue
public java.time.temporal.TemporalAmount temporalAmountValue() throws java.time.DateTimeExceptionDescription copied from interface:LiteralRetrieves thetemporal amountvalue of this literal.A temporal amount representation can be given for literals whose label conforms to the syntax of the XML Schema 2 xsd:duration datatype.
The adoption of the XML Schema 2 definition is a known deviation from the RDF 1.1 standard; well-formedness rules are relaxed to consider all duration components as optional and freely mixable.
Temporal amount representations may be converted to specific
java.timevalues likeDurationusing target static factory methods, for instanceDuration.from(literal.temporalAmountValue()).Note however that
java.timedoesn't include dedicated classes for legal XML Schema duration values including both date and time components (for instance,P1YT23H).- Specified by:
temporalAmountValuein interfaceLiteral- Overrides:
temporalAmountValuein classAbstractLiteral- Returns:
- the temporal amount value of this literal
- Throws:
java.time.DateTimeException- if this literal cannot be represented by aTemporalAmountvalue- See Also:
- The Java™ Tutorials – Trail: Date Time
-
getCoreDatatype
public CoreDatatype.XSD getCoreDatatype()
Description copied from interface:LiteralCoreDatatype 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.
