#### GDurationBuilder

    public GDurationBuilder(GDurationSpecification gDuration)

Constructs a GDurationBuilder from another GDurationBuilderSpecification.

### Method Detail

#### clone

    public Object clone()

Builds another GDurationBuilder with the same value as this one.

Overrides:
  `clone` in class `Object`

#### toGDuration

    public GDuration toGDuration()

Builds a GDuration from this GDurationBuilder.

#### addGDuration

    public void addGDuration(GDurationSpecification duration)

Adds to this duration. Does a fieldwise add, with no normalization.

#### subtractGDuration

    public void subtractGDuration(GDurationSpecification duration)

Subtracts from this duration. Does a fieldwise subtraction, with no normalization.

#### setSign

    public final void setSign(int sign)

Sets the sign.

#### setYear

    public void setYear(int year)

Sets the year component.

#### setMonth

    public void setMonth(int month)

Sets the month component.

#### setDay

    public void setDay(int day)

Sets the day component.

#### setHour

    public void setHour(int hour)

Sets the hour component.

#### setMinute

    public void setMinute(int minute)

Sets the minute component.

#### setSecond

    public void setSecond(int second)

Sets the second component.

#### setFraction

    public void setFraction(BigDecimal fraction)

Sets the fraction-of-second component.

#### isImmutable

    public final boolean isImmutable()

All GDuration instances return true.

Specified by:
  `isImmutable` in interface `GDurationSpecification`

#### getSign

    public final int getSign()

Returns the sign of the duration: +1 is forwards and -1 is backwards in time. This value does not necessarily reflect the true direction of the duration if the duration is not normalized or not normalizable.

Specified by:
  `getSign` in interface `GDurationSpecification`

#### getYear

    public final int getYear()

Gets the year component.

Specified by:
  `getYear` in interface `GDurationSpecification`

#### getMonth

    public final int getMonth()

Gets the month-of-year component.

Specified by:
  `getMonth` in interface `GDurationSpecification`

#### getDay

    public final int getDay()

Gets the day-of-month component.

Specified by:
  `getDay` in interface `GDurationSpecification`

#### getHour

    public final int getHour()

Gets the hour-of-day component.

Specified by:
  `getHour` in interface `GDurationSpecification`

#### getMinute

    public final int getMinute()

Gets the minute-of-hour component.

Specified by:
  `getMinute` in interface `GDurationSpecification`

#### getSecond

    public final int getSecond()

Gets the second-of-minute component.

Specified by:
  `getSecond` in interface `GDurationSpecification`

#### getFraction

    public BigDecimal getFraction()

Gets the fraction-of-second. Range from 0 (inclusive) to 1 (exclusive).

Specified by:
  `getFraction` in interface `GDurationSpecification`

#### isValid

    public boolean isValid()

Returns true if all of the individual components of the duration are nonnegative.

Specified by:
  `isValid` in interface `GDurationSpecification`

#### normalize

    public void normalize()

Normalize a duration value. This ensures that months, hours, minutes, seconds, and fractions are positive and within the ranges 0..11, 0..23, 0..59, etc. Negative durations are indicated by a negative sign rather than negative components.

Most duration specifications can be normalized to valid durations with all positive components, but not all of them can.

The only situations which cannot be normalized are where the year/month and the day/hour/minute/second offsets are of opposite sign. Days cannot be carried into months since the length of a Gregorian month is variable depending on when the duration is applied. In these cases, this method normalizes the components so that "day" is the only negative component.

#### compareToGDuration

    public final int compareToGDuration(GDurationSpecification duration)

Comparison to another GDuration.

- Returns -1 if this < duration. (less-than)
- Returns 0 if this == duration. (equal)
- Returns 1 if this > duration. (greater-than)
- Returns 2 if this <> duration. (incomparable)

Two instances are incomparable if they have different amounts of information.

Specified by:
  `compareToGDuration` in interface `GDurationSpecification`

#### toString

    public String toString()

The natural string representation of the duration.

Any components that are zero are omitted. Note that if the duration is invalid, i.e., it has negative components, those negative components are serialized out here. To check for validity, use the isValid() method; and to normalize most durations to a valid form use the normalize() method.

Overrides:
  `toString` in class `Object`

#### toPlainString

    public static String toPlainString(BigDecimal bd)

#### stripTrailingZeros

    public static String stripTrailingZeros(String s)
