Package org.apache.jena.datatypes.xsd.impl

Class XSDFloat

java.lang.Object

org.apache.jena.datatypes.BaseDatatype

org.apache.jena.datatypes.xsd.XSDDatatype

org.apache.jena.datatypes.xsd.impl.XSDFloat

All Implemented Interfaces:

RDFDatatype

public class XSDFloat
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 Detail

XSDFloat

public XSDFloat(java.lang.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.

XSDFloat

public XSDFloat(java.lang.String typeName,
                java.lang.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 Detail

isValidValue

public boolean isValidValue(java.lang.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 java.lang.Object parse(java.lang.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 java.lang.String unparse(java.lang.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 java.lang.Object parseValidated(java.lang.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
