public final class DayTimeDurationValue extends DurationValue implements Comparable
A value of type xs:dayTimeDuration
  • Constructor Details

    • DayTimeDurationValue

      public DayTimeDurationValue(int sign, int days, int hours, int minutes, long seconds, int microseconds) throws IllegalArgumentException
      Create a dayTimeDuration given the number of days, hours, minutes, and seconds. This constructor performs no validation. The components (apart from sign) must all be non-negative integers; they need not be normalized (for example, 36 hours is acceptable)
      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:
      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
  • Method Details

    • makeDayTimeDurationValue

      public static ConversionResult makeDayTimeDurationValue(CharSequence s)
      Factory method: create a duration value from a supplied string, in ISO 8601 format [-]PnDTnHnMnS
      Parameters:
      s - the lexical representation of the xs:dayTimeDuration value
      Returns:
      a DayTimeDurationValue if the format is correct, or a ValidationErrorValue if not
    • copyAsSubType

      public AtomicValue copyAsSubType(AtomicType typeLabel)
      Create a copy of this atomic value, with a different type label
      Overrides:
      copyAsSubType in class DurationValue
      Parameters:
      typeLabel - the type label of the new copy. The caller is responsible for checking that the value actually conforms to this type.
      Returns:
      the copied value
    • getPrimitiveType

      public BuiltInAtomicType getPrimitiveType()
      Determine the primitive type of the value. This delivers the same answer as getItemType().getPrimitiveItemType(). The primitive types are the 19 primitive types of XML Schema, plus xs:integer, xs:dayTimeDuration and xs:yearMonthDuration, and xs:untypedAtomic. For external objects, the result is AnyAtomicType.
      Overrides:
      getPrimitiveType in class DurationValue
      Returns:
      the primitive type
    • getPrimitiveStringValue

      public CharSequence getPrimitiveStringValue()
      Convert to string
      Overrides:
      getPrimitiveStringValue in class DurationValue
      Returns:
      ISO 8601 representation.
    • getLengthInSeconds

      public double getLengthInSeconds()
      Get length of duration in seconds
      Overrides:
      getLengthInSeconds in class DurationValue
      Returns:
      the duration in seconds, as a double
    • getLengthInMicroseconds

      public long getLengthInMicroseconds()
      Get length of duration in microseconds, as a long
      Returns:
      the length in microseconds
    • fromSeconds

      public static DayTimeDurationValue fromSeconds(BigDecimal seconds)
      Construct a duration value as a number of seconds.
      Parameters:
      seconds - the number of seconds in the duration. May be negative
      Returns:
      the xs:dayTimeDuration value with the specified length
    • fromMilliseconds

      public static DayTimeDurationValue fromMilliseconds(long milliseconds) throws ValidationException
      Construct a duration value as a number of milliseconds.
      Parameters:
      milliseconds - the number of milliseconds in the duration (may be negative)
      Returns:
      the corresponding xs:dayTimeDuration value
      Throws:
      ValidationException - if implementation-defined limits are exceeded, specifically if the total number of seconds exceeds 2^63.
    • fromMicroseconds

      public static DayTimeDurationValue fromMicroseconds(long microseconds) throws IllegalArgumentException
      Construct a duration value as a number of microseconds.
      Parameters:
      microseconds - the number of microseconds in the duration. The maximum and minimum limits are such that the number of days in the duration must fit in a 32-bit signed integer.
      Returns:
      the xs:dayTimeDuration represented by the given number of microseconds
      Throws:
      IllegalArgumentException - if the value is out of range.
    • multiply

      public DurationValue multiply(double n) throws XPathException
      Multiply duration by a number. This is also used when dividing a duration by a number.
      Overrides:
      multiply in class DurationValue
      Parameters:
      n - the number to multiply by
      Returns:
      the result of the multiplication
      Throws:
      XPathException
    • divide

      public DecimalValue divide(DurationValue other) throws XPathException
      Find the ratio between two durations
      Overrides:
      divide in class DurationValue
      Parameters:
      other - the dividend
      Returns:
      the ratio, as a decimal
      Throws:
      XPathException
    • add

      public DurationValue add(DurationValue other) throws XPathException
      Add two dayTimeDurations
      Overrides:
      add in class DurationValue
      Parameters:
      other - the duration to be added to this one
      Returns:
      the sum of the two durations
      Throws:
      XPathException
    • subtract

      public DurationValue subtract(DurationValue other) throws XPathException
      Subtract two dayTime-durations
      Overrides:
      subtract in class DurationValue
      Parameters:
      other - the duration to be subtracted from this one
      Returns:
      the difference of the two durations
      Throws:
      XPathException
    • negate

      public DurationValue negate() throws IllegalArgumentException
      Negate a duration (same as subtracting from zero, but it preserves the type of the original duration)
      Overrides:
      negate in class DurationValue
      Returns:
      the original duration with its sign reversed, retaining its type
      Throws:
      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)
    • compareTo

      public int compareTo(Object other)
      Compare the value to another duration value
      Specified by:
      compareTo in interface Comparable
      Parameters:
      other - The other dateTime value
      Returns:
      negative value if this one is the earler, 0 if they are chronologically equal, positive value if this one is the later. For this purpose, dateTime values with an unknown timezone are considered to be UTC values (the Comparable interface requires a total ordering).
      Throws:
      ClassCastException - if the other value is not a DateTimeValue (the parameter is declared as Object to satisfy the Comparable interface)
    • getXPathComparable

      public Object getXPathComparable(boolean ordered, StringCollator collator, XPathContext context)
      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:
      getXPathComparable in class DurationValue
      Parameters:
      ordered - true if an ordered comparable is needed
      collator - Collation used for string comparison
      context - 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
