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.
-
byteValue
public byte byteValue()
Description copied from interface:LiteralReturns the byte value of this literal.- Specified by:
byteValuein interfaceLiteral- Overrides:
byteValuein classAbstractLiteral- Returns:
- The byte value of the literal.
-
shortValue
public short shortValue()
Description copied from interface:LiteralReturns the short value of this literal.- Specified by:
shortValuein interfaceLiteral- Overrides:
shortValuein classAbstractLiteral- Returns:
- The short value of the literal.
-
intValue
public int intValue()
Description copied from interface:LiteralReturns the int value of this literal.- Specified by:
intValuein interfaceLiteral- Overrides:
intValuein classAbstractLiteral- Returns:
- The int value of the literal.
-
longValue
public long longValue()
Description copied from interface:LiteralReturns the long value of this literal.- Specified by:
longValuein interfaceLiteral- Overrides:
longValuein classAbstractLiteral- Returns:
- The long value of the literal.
-
floatValue
public float floatValue()
Description copied from interface:LiteralReturns the float value of this literal.- Specified by:
floatValuein interfaceLiteral- Overrides:
floatValuein classAbstractLiteral- Returns:
- The float value of the literal.
-
doubleValue
public double doubleValue()
Description copied from interface:LiteralReturns the double value of this literal.- Specified by:
doubleValuein interfaceLiteral- Overrides:
doubleValuein classAbstractLiteral- Returns:
- The double value of the literal.
-
getCoreDatatype
public CoreDatatype 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.
