## Class GDuration

- java.lang.Object
- - org.apache.xmlbeans.GDuration

All Implemented Interfaces:
  Serializable, GDurationSpecification

    public final class GDuration
    extends Object
    implements GDurationSpecification, Serializable

Represents an XML Schema-compatible duration.

A duration is made up of a number of years, months, days, hours, minutes, seconds, and fractions of seconds. See the XML Schema specification section on xs:duration for details on the rules for comparing durations and adding durations to dates.

### Constructor Summary

Constructors
Constructor and Description
`GDuration()` Constructs an empty GDuration representing zero seconds.
`GDuration(CharSequence str)` Constructs a GDuration from a lexical representation.
`GDuration(GDurationSpecification gDuration)` Constructs a GDuration from another GDurationSpecification.
`GDuration(int sign, int year, int month, int day, int hour, int minute, int second, BigDecimal fraction)` Constructs a GDuration with the specified sign, year, month, day, hours, minutes, seconds, and optional fractional seconds.

### Method Summary

All Methods Instance Methods Concrete Methods
`GDuration` `add(GDurationSpecification duration)` Returns a new GDuration which is the sum of this one and the supplied duration.
`Object` `clone()` Builds another GDate with the same value as this one.
`int` `compareToGDuration(GDurationSpecification duration)` Comparison to another GDuration.
`boolean` `equals(Object obj)` Two GDurations are equal if all their fields are equal.
`int` `getDay()` Gets the day-of-month component.
`BigDecimal` `getFraction()` Gets the fraction-of-second.
`int` `getHour()` Gets the hour-of-day component.
`int` `getMinute()` Gets the minute-of-hour component.
`int` `getMonth()` Gets the month-of-year component.
`int` `getSecond()` Gets the second-of-minute component.
`int` `getSign()` Returns the sign of the duration: +1 is forwards and -1 is backwards in time.
`int` `getYear()` Gets the year component.
`int` `hashCode()`
`boolean` `isImmutable()` All GDuration instances return true.
`boolean` `isValid()` Returns true if all of the individual components of the duration are nonnegative.
`GDuration` `subtract(GDurationSpecification duration)` Returns a new GDuration which is the result of subtracting the supplied duration from this one.
`String` `toString()` The natural string representation of the duration.

### Constructor Detail

#### GDuration

    public GDuration()

Constructs an empty GDuration representing zero seconds.

#### GDuration

    public GDuration(CharSequence str)

Constructs a GDuration from a lexical representation. The lexical space contains the union of the lexical spaces of all the schema date/time types (except for duration).

#### GDuration

    public GDuration(int sign,
                     int year,
                     int month,
                     int day,
                     int hour,
                     int minute,
                     int second,
                     BigDecimal fraction)

Constructs a GDuration with the specified sign, year, month, day, hours, minutes, seconds, and optional fractional seconds.

Parameters:
  `sign` - +1 for a positive duration, -1 for a negative duration
Throws:
  `IllegalArgumentException` - if the sign is not 1 or -1

#### GDuration

    public GDuration(GDurationSpecification gDuration)

Constructs a GDuration from another GDurationSpecification.

### Method Detail

#### clone

    public Object clone()

Builds another GDate with the same value as this one.

Overrides:
  `clone` in class `Object`

#### 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.

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`

#### 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`

#### add

    public GDuration add(GDurationSpecification duration)

Returns a new GDuration which is the sum of this one and the supplied duration. Does a fieldwise addition, with no normalization.

#### subtract

    public GDuration subtract(GDurationSpecification duration)

Returns a new GDuration which is the result of subtracting the supplied duration from this one. Does a fieldwise subtraction, with no normalization.

#### equals

    public boolean equals(Object obj)

Two GDurations are equal if all their fields are equal. The equals function does not apply normalizatin.

Overrides:
  `equals` in class `Object`

#### hashCode

    public int hashCode()

Overrides:
  `hashCode` in class `Object`
