public class TaiwanCalendar
extends GregorianCalendar

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".

Constructor Details

TaiwanCalendar

public TaiwanCalendar()

Constructs a TaiwanCalendar using the current time in the default time zone with the default locale.

TaiwanCalendar

public TaiwanCalendar(TimeZone zone)

Constructs a TaiwanCalendar based on the current time in the given time zone with the default locale.

Parameters:

zone - the given time zone.

TaiwanCalendar

public TaiwanCalendar(Locale aLocale)

Constructs a TaiwanCalendar based on the current time in the default time zone with the given locale.

Parameters:

aLocale - the given locale.

TaiwanCalendar

public TaiwanCalendar(ULocale locale)

Constructs a TaiwanCalendar based on the current time in the default time zone with the given locale.

Parameters:

locale - the given ulocale.

TaiwanCalendar

public TaiwanCalendar(TimeZone zone,
 Locale aLocale)

Constructs a TaiwanCalendar based on the current time in the given time zone with the given locale.

Parameters:

zone - the given time zone.

TaiwanCalendar

public TaiwanCalendar(TimeZone zone,
 ULocale locale)

Constructs a TaiwanCalendar based on the current time in the given time zone with the given locale.

Parameters:

zone - the given time zone.

locale - the given ulocale.

TaiwanCalendar

public TaiwanCalendar(Date date)

Constructs a TaiwanCalendar with the given date set in the default time zone with the default locale.

Parameters:

date - The date to which the new calendar is set.

TaiwanCalendar

public TaiwanCalendar(int year,
 int month,
 int date)

Constructs a TaiwanCalendar with the given date set in the default time zone with the default locale.

Parameters:

year - The value used to set the calendar's YEAR time field.

month - The value used to set the calendar's MONTH time field. The value is 0-based. e.g., 0 for January.

second - The value used to set the calendar's SECOND time field.

Method Details

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.

Overrides:

handleGetExtendedYear in class GregorianCalendar

Returns:

the extended year

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

Overrides:

handleComputeFields in class GregorianCalendar

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.

Overrides:

handleGetLimit in class GregorianCalendar

Parameters:

field - one of the above field numbers

limitType - one of MINIMUM, GREATEST_MINIMUM, LEAST_MAXIMUM, or MAXIMUM

getType

public String getType()

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

Overrides:

getType in class GregorianCalendar

Returns:

legacy calendar type name string
