class:IsoEra [NONE]

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

public enum IsoEra
extends Enum<IsoEra>
implements Era

An era in the ISO calendar system.

The ISO-8601 standard does not define eras. A definition has therefore been created with two eras - 'Current era' (CE) for years on or after 0001-01-01 (ISO), and 'Before current era' (BCE) for years before that.
ISO years and eras

year-of-era era proleptic-year

2 CE 2

1 CE 1

1 BCE 0

2 BCE -1

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

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

field:BCE [NONE]

BCE

public static final IsoEra BCE

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

field:CE [NONE]

CE

public static final IsoEra CE

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

method:values() [NONE]

values

public static IsoEra[] values()

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

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

method:valueOf(java.lang.String) [NONE]

valueOf

public static IsoEra 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

method:of(int) [NONE]

of

public static IsoEra of(int isoEra)

Obtains an instance of IsoEra from an int value.

IsoEra is an enum representing the ISO eras of BCE/CE. This factory allows the enum to be obtained from the int value.

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

method:getValue() [NONE]

getValue

public int getValue()

Gets the numeric era int value.

The era BCE has the value 0, while the era CE has the value 1.

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