java.lang.Comparable<AbstractDateTime>
- Direct Known Subclasses:
XSDDateTime
,XSDDuration
public class AbstractDateTime extends java.lang.Object implements java.lang.Comparable<AbstractDateTime>
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 includes code derived from Xerces 2.6.0 Copyright (c) 1999-2002 The Apache Software Foundation.

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
-
compareTo
public int compareTo(AbstractDateTime o)
Normal java comparison function. Treats INDETERMINATE as the same as equals. This is not strictly correct but seems like an appropriate way to handle partially ordered objects.- Specified by:
compareTo
in interfacejava.lang.Comparable<AbstractDateTime>
-
equals
public boolean equals(java.lang.Object obj)
Equality function- Overrides:
equals
in classjava.lang.Object
-
hashCode
public int hashCode()
- Overrides:
hashCode
in classjava.lang.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
