Class DayTimeDurationValue

    • Constructor Detail

      • DayTimeDurationValue

        public DayTimeDurationValue​(int sign,
                            int days,
                            int hours,
                            int minutes,
                            long seconds,
                            int microseconds)
                     throws java.lang.IllegalArgumentException
        Create a dayTimeDuration given the number of days, hours, minutes, and seconds. This constructor performs limited validation. The components (apart from sign) must all be non-negative integers; they need not be normalized (for example, 36 hours is acceptable)

        Note: for historic reasons this constructor only supports microsecond precision. For nanosecond precision, use the constructor DayTimeDurationValue(int, int, int, long, int)

        Parameters:
        sign - positive number for positive durations, negative for negative duratoins
        days - number of days
        hours - number of hours
        minutes - number of minutes
        seconds - number of seconds
        microseconds - number of microseconds
        Throws:
        java.lang.IllegalArgumentException - if the value is out of range; specifically, if the total number of seconds exceeds 2^63; or if any of the values is negative

      • DayTimeDurationValue

        public DayTimeDurationValue​(int days,
                            int hours,
                            int minutes,
                            long seconds,
                            int nanoseconds)
                     throws java.lang.IllegalArgumentException
        Create a dayTimeDuration given the number of days, hours, minutes, seconds, and nanoseconds. This constructor performs limited validation. The components need not be normalized (for example, 36 hours is acceptable)

        To construct a positive duration, all the component values should be positive integers (or zero). To construct a negative duration, all the component values should be negative integers (or zero).

        Parameters:
        days - number of days
        hours - number of hours
        minutes - number of minutes
        seconds - number of seconds
        nanoseconds - number of nanoseconds
        Throws:
        java.lang.IllegalArgumentException - if the value is out of range; specifically, if the total number of seconds exceeds 2^63; or if some values are positive and others are negative

        public DurationValue negate()
                     throws java.lang.IllegalArgumentException

        Overrides:
        negate in class DurationValue
        Returns:
        the original duration with its sign reversed, retaining its type
        Throws:
        java.lang.IllegalArgumentException - in the extremely unlikely event that the duration is one that cannot be negated (because the limit for positive durations is one second off from the limit for negative durations)

      • getXPathComparable

        public XPathComparable getXPathComparable​(StringCollator collator,
                                          int implicitTimezone)
        Description copied from class: AtomicValue
        Get an object value that implements the XPath equality and ordering comparison semantics for this value. A collation is supplied for comparing strings, and an implicit timezone for comparing date/time values that have no saved timezone. An atomic value may return itself as the result, provided that its ordering rules are independent of the collation and timezone, and provided that it implements the XPathComparable interface: which means that its compareTo, equals, and hashCode methods must be compatible with the rules for XPath value comparisons.
        Overrides:
        getXPathComparable in class DurationValue
        Parameters:
        collator - the collation to be used when comparing strings
        implicitTimezone - the implicit timezone in the dynamic context, used when comparing dates/times with and without timezone
        Returns:
        an Object that implements the XPath value comparison semantics with respect to this atomic value. For an atomic type that is not ordered (according to XPath rules), return null.

      • getXPathComparable

        public XPathComparable getXPathComparable()
        Description copied from interface: ContextFreeAtomicValue
        Get an XPathComparable object that supports the semantics of context-free eq and lt comparisons between atomic values. Note that in many cases the returned XPathComparable will be the AtomicValue itself; however because of the constraints of the generic Comparable interface, this cannot be assumed.
        Specified by:
        getXPathComparable in interface ContextFreeAtomicValue
        Returns:
        an XPathComparable that can be used in comparisons with other atomic values.

      • compareTo

        public int compareTo​(XPathComparable other)
        Compare the value to another duration value
        Specified by:
        compareTo in interface java.lang.Comparable<XPathComparable>
        Parameters:
        other - The other dateTime value
        Returns:
        negative value if this one is the smaller, 0 if they are equal, positive value if this one is the greater.
        Throws:
        java.lang.ClassCastException - if the other value is not a DayTimeDurationValue

      • getXPathMatchKey

        public AtomicMatchKey getXPathMatchKey​(StringCollator collator,
                                       int implicitTimezone)
        Get a Comparable value that implements the XPath ordering comparison semantics for this value. Returns null if the value is not comparable according to XPath rules. The default implementation returns the value itself. This is modified for types such as xs:duration which allow ordering comparisons in XML Schema, but not in XPath.
        Overrides:
        getXPathMatchKey in class DurationValue
        Parameters:
        collator - Collation used for string comparison
        implicitTimezone - XPath dynamic context
        Returns:
        an Object whose equals() and hashCode() methods implement the XPath comparison semantics with respect to this atomic value. If ordered is specified, the result will either be null if no ordering is defined, or will be a Comparable
