Class AbstractDateTime

java.lang.Object
org.apache.jena.datatypes.xsd.AbstractDateTime
All Implemented Interfaces:
Comparable<AbstractDateTime>
Direct Known Subclasses:
XSDDateTime, XSDDuration
public class AbstractDateTime extends Object implements 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. All rights reserved.

    • LESS_THAN

      public static final short LESS_THAN
      constant to indicate a less than relationship from compare()

  • Constructor Details

    • AbstractDateTime

      public AbstractDateTime(Object value)
      Constructor
      Parameters:
      value - the date/time value returned by the parsing

  • Method Details

    • 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 interface Comparable<AbstractDateTime>

    • equals

      public boolean equals(Object obj)
      Equality function
      Overrides:
      equals in class Object

    • hashCode

      public int hashCode()
      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
