Class XMLDateTime

java.lang.Object

org.openrdf.model.datatypes.XMLDateTime

All Implemented Interfaces:

Cloneable, Comparable<XMLDateTime>

public class XMLDateTime
extends Object
implements Cloneable, Comparable<XMLDateTime>

This class provides utility functions for comparisons operating on xml:dateTime datatypes as specified in W3C XML Schema Definition Language (XSD) 1.1 Part 2: Datatypes.

Known deviations from the standard: - the range of years in this implementation is limited to Integer.MIN_VALUE to Integer.MAX_VALUE for practical reasons.
