IsoEra

public final enum IsoEra
extends Enum<IsoEra> implements Era

java.lang.Object
↳	java.lang.Enum<java.time.chrono.IsoEra>
	↳	java.time.chrono.IsoEra

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.

Summary

Enum values
`IsoEra`	`BCE` The singleton instance for the era before the current one, 'Before Current Era', which has the numeric value 0.
`IsoEra`	`CE` The singleton instance for the current era, 'Current Era', which has the numeric value 1.

Public methods
`int`	`getValue()` Gets the numeric era `int` value.
`static IsoEra`	`of(int isoEra)` Obtains an instance of `IsoEra` from an `int` value.
`static IsoEra`	`valueOf(String name)`
`static final IsoEra[]`	`values()`

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.

public int getValue ()

Gets the numeric era int value.

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

Added in API level 26

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.
