# TaiwanCalendar

`public class TaiwanCalendar`
`` `` `extends GregorianCalendar` ``

java.lang.Object
↳ | android.icu.util.Calendar
| ↳ | android.icu.util.GregorianCalendar
|  | ↳ | android.icu.util.TaiwanCalendar

`TaiwanCalendar` is a subclass of `GregorianCalendar` that numbers years since 1912.

The Taiwan calendar is identical to the Gregorian calendar in all respects except for the year and era. Years are numbered since 1912 AD (Gregorian).

The Taiwan Calendar has one era: `MINGUO`.

This class should not be subclassed.

TaiwanCalendar usually should be instantiated using `Calendar.getInstance(ULocale)` passing in a `ULocale` with the tag `"@calendar=roc"`.

- `Calendar`
- `GregorianCalendar`

## Public methods

### getType

    public String getType ()

[icu] Returns the calendar type name string for this Calendar object. The returned string is the legacy ICU calendar attribute value, for example, "gregorian" or "japanese".

See type="old type name" for the calendar attribute of locale IDs at http://www.unicode.org/reports/tr35/#Key_Type_Definitions

Returns
`String` | legacy calendar type name string

## Protected methods

### handleComputeFields

    protected void handleComputeFields (int julianDay)

Override Calendar to compute several fields specific to the hybrid Gregorian-Julian calendar system. These are:

- ERA
- YEAR
- MONTH
- DAY_OF_MONTH
- DAY_OF_YEAR
- EXTENDED_YEAR

Parameters
`julianDay` | `int`

### handleGetExtendedYear

    protected int handleGetExtendedYear ()

Returns the extended year defined by the current fields. This will use the EXTENDED_YEAR field or the YEAR and supra-year fields (such as ERA) specific to the calendar system, depending on which set of fields is newer.

Returns
`int` | the extended year

### handleGetLimit

    protected int handleGetLimit (int field,
                    int limitType)

Override GregorianCalendar. There is only one Taiwan ERA. We should really handle YEAR, YEAR_WOY, and EXTENDED_YEAR here too to implement the 1..5000000 range, but it's not critical.

Parameters
`field` | `int`: one of the above field numbers
`limitType` | `int`: one of `MINIMUM`, `GREATEST_MINIMUM`, `LEAST_MAXIMUM`, or `MAXIMUM`

Returns
`int` |
