Constructor Detail

### 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 Detail

### 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

### getLengthInMilliseconds

    public long getLengthInMilliseconds()

  Get length of duration in milliseconds, as a long

  Returns:
    the length of the duration rounded to milliseconds (may be negative)

### 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
