  • Constructor Details

    • XSDDatatype

      public XSDDatatype(String typeName)
      Constructor.
      Parameters:
      typeName - the name of the XSD type to be instantiated, this is used to lookup a type definition from the Xerces schema factory.

    • XSDDatatype

      public XSDDatatype(String typeName, Class<?> javaClass)
      Constructor.
      Parameters:
      typeName - the name of the XSD type to be instantiated, this is used to lookup a type definition from the Xerces schema factory.
      javaClass - the java class for which this xsd type is to be treated as the canonical representation

  • Method Details

    • parse

      public Object parse(String lexicalForm) throws DatatypeFormatException
      Parse a lexical form of this datatype to a value
      Specified by:
      parse in interface RDFDatatype
      Overrides:
      parse in class BaseDatatype
      Throws:
      DatatypeFormatException - if the lexical form is not legal

    • unparse

      public String unparse(Object value)
      Convert a value of this datatype out to lexical form.
      Specified by:
      unparse in interface RDFDatatype
      Overrides:
      unparse in class BaseDatatype

    • isEqual

      public boolean isEqual(LiteralLabel value1, LiteralLabel value2)
      Compares two instances of values of the given datatype.
      Specified by:
      isEqual in interface RDFDatatype
      Overrides:
      isEqual in class BaseDatatype

    • getJavaClass

      public Class<?> getJavaClass()
      If this datatype is used as the cannonical representation for a particular java datatype then return that java type, otherwise returns null.
      Specified by:
      getJavaClass in interface RDFDatatype
      Overrides:
      getJavaClass in class BaseDatatype

    • extendedTypeDefinition

      public Object extendedTypeDefinition()
      Returns the Xerces datatype representation for this type, this is an XSSimpleType, in fact an XSSimpleTypeDecl.
      Specified by:
      extendedTypeDefinition in interface RDFDatatype
      Overrides:
      extendedTypeDefinition in class BaseDatatype

    • parseValidated

      public Object parseValidated(String lexical)
      Parse a validated lexical form. Subclasses which use the default parse implementation and are not convered by the explicit convertValidatedData cases should override this.

    • isValidLiteral

      public boolean isValidLiteral(LiteralLabel lit)
      Test whether the given LiteralLabel is a valid instance of this datatype. This takes into account typing information as well as lexical form - for example an xsd:string is never considered valid as an xsd:integer (even if it is lexically legal like "1").
      Specified by:
      isValidLiteral in interface RDFDatatype
      Overrides:
      isValidLiteral in class BaseDatatype

    • isBaseTypeCompatible

      public boolean isBaseTypeCompatible(LiteralLabel lit)
      Test if the given typed value is in the right partition of the XSD type space. If this test passes then if the typed value has a legal lexical form for this type then it is a legal instance.

    • trimPlus

      public static String trimPlus(String str)
      Helper function to return the substring of a validated number string omitting any leading + sign.

    • loadXSDSimpleTypes

      public static void loadXSDSimpleTypes(TypeMapper tm)
      Add all of the XSD pre-defined simple types to the given type mapper registry.

    • main

      public static void main(String[] args)
