Method Detail

### getStringValue

    public java.lang.String getStringValue()

  Convert to string

  Specified by:
    `getStringValue` in interface `Item`
  Overrides:
    `getStringValue` in class `DurationValue`
  Returns:
    ISO 8601 representation.

### normalize

    public void normalize()

  Normalize the value, for example 90M becomes 1H30M

### getLengthInMonths

    public int getLengthInMonths()

  Get the number of months in the duration

### fromMonths

    public static MonthDurationValue fromMonths(int months)

  Construct a duration value as a number of months.

### multiply

    public DurationValue multiply(double n,
                                  XPathContext context)

  Multiply duration by a number

  Overrides:
    `multiply` in class `DurationValue`

### divide

    public DoubleValue divide(DurationValue other,
                              XPathContext context)
                       throws XPathException

  Overrides:
    `divide` in class `DurationValue`
  Parameters:
    `other` - the dividend
  Returns:
    the ratio, as a double
  Throws:
    `XPathException`

### add

    public DurationValue add(DurationValue other,
                             XPathContext context)
                      throws XPathException

  Add two year-month-durations

  Overrides:
    `add` in class `DurationValue`
  Throws:
    `XPathException`

### subtract

    public DurationValue subtract(DurationValue other,
                                  XPathContext context)
                           throws XPathException

  Subtract two year-month-durations

  Overrides:
    `subtract` in class `DurationValue`
  Throws:
    `XPathException`

### getItemType

    public ItemType getItemType()

  Determine the data type of the exprssion

  Specified by:
    `getItemType` in interface `Expression`
  Overrides:
    `getItemType` in class `DurationValue`
  Returns:
    Type.YEAR_MONTH_DURATION,

### convertToJava

    public java.lang.Object convertToJava(java.lang.Class target,
                                          XPathContext context)
                                   throws XPathException

  Overrides:
    `convertToJava` in class `DurationValue`
  Throws:
    `XPathException`

### compareTo

    public int compareTo(java.lang.Object other)

  Compare the value to another duration value

  Specified by:
    `compareTo` in interface `java.lang.Comparable`
  Overrides:
    `compareTo` in class `DurationValue`
  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:
    `java.lang.ClassCastException` - if the other value is not a DateTimeValue (the parameter is declared as Object to satisfy the Comparable interface)
