    • parseBoolean

      static Boolean parseBoolean(String label)

    • 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.XSD 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.

    • booleanValue

      public boolean booleanValue()
      Description copied from interface: Literal
      Returns the boolean value of this literal.
      Specified by:
      booleanValue in interface Literal
      Overrides:
      booleanValue in class AbstractLiteral
      Returns:
      The boolean value of the literal.
