Class AbstractDateTime

  • All Implemented Interfaces:
    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. All rights reserved.

    • Constructor Detail

      • AbstractDateTime

        public AbstractDateTime​(java.lang.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

      • 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 java.lang.Comparable<AbstractDateTime>

      • equals

        public boolean equals​(java.lang.Object obj)
        Equality function
        Overrides:
        equals in class java.lang.Object

      • hashCode

        public int hashCode()
        Overrides:
        hashCode in class java.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
