Class AbstractDateTime

java.lang.Object
  extended by com.hp.hpl.jena.datatypes.xsd.AbstractDateTime
Direct Known Subclasses:
XSDDateTime, XSDDuration

public class AbstractDateTime
extends Object

Base class for representation of XSD duration, time, date/time and related datatype instances. We are using the Xerces internal packages for the all heavy lifting which represent date/times using an int array. These wrapper classes just provide more convenient access to the date values.

This class includees code derived from Xerces 2.6.0 Copyright (c) 1999-2002 The Apache Software Foundation. All rights reserved.

Constructor Detail

AbstractDateTime

public AbstractDateTime(Object value)
Constructor

Parameters:
value - the date/time value returned by the parsing
Method Detail

compare

public int compare(AbstractDateTime other)
Comparison function. Not quite the same as normal java compare because XSD date/times are not always comparable.

Parameters:
other - the time/date to compare to
Returns:
an order flag - one of LESS_THAN, EQUAL, GREATER_THEN, INDETERMINATE

equals

public boolean equals(Object obj)
Equality function

Overrides:
equals in class Object

hashCode

public int hashCode()
hash function

Overrides:
hashCode in class Object

normalize

public static void normalize(int[] date,
                             int[] timeZone)
If timezone present - normalize dateTime [E Adding durations to dateTimes] Public to allow reuse with type objects.

Parameters:
date - CCYY-MM-DDThh:mm:ss+03
