org.apache.jena.datatypes.xsd.impl.XSDDouble

All Implemented Interfaces:

RDFDatatype

public class XSDDouble
extends XSDDatatype

Datatype representation for xsd:float. Can't just use XSDBaseNumericType because float, double and decimal are all disjoint in XSD. Can use plain XSDDatatype because the equality function needs overriding.

Constructor Details

XSDDouble

public XSDDouble(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.

XSDDouble

public XSDDouble(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 cannonical representation

Method Details

isValidValue

public boolean isValidValue(Object valueForm)

Test whether the given object is a legal value form of this datatype. Brute force implementation.

Specified by:

isValidValue in interface RDFDatatype

Overrides:

isValidValue in class BaseDatatype

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 XSDDatatype

Throws:

DatatypeFormatException - if the lexical form is not legal

unparse

public String unparse(Object value)

Description copied from class: XSDDatatype

Convert a value of this datatype out to lexical form.

Specified by:

unparse in interface RDFDatatype

Overrides:

unparse in class XSDDatatype

parseValidated

public Object parseValidated(String lex)

Parse a validated lexical form. Subclasses which use the default parse implementation and are not converted by the explicit convertValidatedData cases should override this.

Overrides:

parseValidated in class XSDDatatype

isEqual

public boolean isEqual(LiteralLabel value1,
 LiteralLabel value2)

Compares two instances of values of the given datatype. This ignores lang tags and just uses the java.lang.Number equality.

Specified by:

isEqual in interface RDFDatatype

Overrides:

isEqual in class XSDDatatype
