Enum IsoEra

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.

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.

Enum Constants

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.

CE

public static final IsoEra CE

Methods

values

public static IsoEra[] 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 (IsoEra c : IsoEra.values())
    System.out.println(c);

Returns:

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

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.)

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 IsoEra of(int isoEra)

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

getValue

public int getValue()

Specified by:
