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.

temporalAccessorValue

public TemporalAccessor temporalAccessorValue()

Description copied from interface: Literal

Retrieves the temporal 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:

• xsd:dateTime,
• xsd:time,
• xsd:date,
• xsd:gYearMonth,
• xsd:gYear,
• xsd:gMonthDay,
• xsd:gDay,
• xsd:gMonth.

Temporal accessor representations may be converted to specific java.time values like OffsetDateTime using target static factory methods, for instance OffsetDateTime.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) and xsd:gDay (for instance, ---16).

Specified by:

temporalAccessorValue in interface Literal

Overrides:

temporalAccessorValue in class AbstractLiteral

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

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.
