Enum MinguoEra

java.lang.Object
- java.lang.Enum<MinguoEra>
- - java.time.chrono.MinguoEra

All Implemented Interfaces:: Serializable, Comparable<MinguoEra>, Era, TemporalAccessor, TemporalAdjuster

public enum MinguoEra
extends Enum<MinguoEra>
implements Era

An era in the Minguo calendar system.

The Minguo calendar system has two eras. The current era, for years from 1 onwards, is known as the 'Republic of China' era. All previous years, zero or earlier in the proleptic count or one and greater in the year-of-era count, are part of the 'Before Republic of China' era.

year-of-era	era	proleptic-year	ISO proleptic-year
2	ROC	2	1913
1	ROC	1	1912
1	BEFORE_ROC	0	1911
2	BEFORE_ROC	-1	1910

Do not use ordinal() to obtain the numeric representation of MinguoEra. Use getValue() instead.

Implementation Requirements:: This is an immutable and thread-safe enum.
Since:: 1.8

Enum Constants

Enum Constant	Description
`BEFORE_ROC`	The singleton instance for the era before the current one, 'Before Republic of China Era', which has the numeric value 0.
`ROC`	The singleton instance for the current era, 'Republic of China Era', which has the numeric value 1.

Methods

Modifier and Type	Method	Description
`String`	`getDisplayName(TextStyle style, Locale locale)`	Gets the textual representation of this era.
`int`	`getValue()`	Gets the numeric era `int` value.
`static MinguoEra`	`of(int minguoEra)`	Obtains an instance of `MinguoEra` from an `int` value.
`static MinguoEra`	`valueOf(String name)`	Returns the enum constant of this type with the specified name.

Enum Constants

BEFORE_ROC

public static final MinguoEra BEFORE_ROC

The singleton instance for the era before the current one, 'Before Republic of China Era', which has the numeric value 0.

ROC

public static final MinguoEra ROC

The singleton instance for the current era, 'Republic of China Era', which has the numeric value 1.

Methods

values

public static MinguoEra[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (MinguoEra c : MinguoEra.values())
    System.out.println(c);

Returns:: an array containing the constants of this enum type, in the order they are declared

valueOf

public static MinguoEra valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:: name - the name of the enum constant to be returned.
Returns:: the enum constant with the specified name
Throws:: IllegalArgumentException - if this enum type has no constant with the specified name; NullPointerException - if the argument is null

of

public static MinguoEra of(int minguoEra)

Obtains an instance of MinguoEra from an int value.

MinguoEra is an enum representing the Minguo eras of BEFORE_ROC/ROC. This factory allows the enum to be obtained from the int value.

Parameters:: minguoEra - the BEFORE_ROC/ROC value to represent, from 0 (BEFORE_ROC) to 1 (ROC)
Returns:: the era singleton, not null
Throws:: DateTimeException - if the value is invalid

getValue

public int getValue()

Gets the numeric era int value.

The era BEFORE_ROC has the value 0, while the era ROC has the value 1.

Specified by:: getValue in interface Era
Returns:: the era value, from 0 (BEFORE_ROC) to 1 (ROC)

getDisplayName

public String getDisplayName(TextStyle style,
                             Locale locale)

Gets the textual representation of this era.

This returns the textual name used to identify the era, suitable for presentation to the user. The parameters control the style of the returned text and the locale.

If no textual mapping is found then the numeric value is returned.

Specified by:: getDisplayName in interface Era
Parameters:: style - the style of the text required, not null; locale - the locale to use, not null
Returns:: the text value of the era, not null
