IsoEra
public final 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.
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. |
Inherited methods |
|---|
From class java.lang.Enum final Object | clone() Throws CloneNotSupportedException. | final int | compareTo(IsoEra o) Compares this enum with the specified object for order. | final boolean | equals(Object other) Returns true if the specified object is equal to this enum constant. | final void | finalize() enum classes cannot have finalize methods. | final Class<IsoEra> | getDeclaringClass() Returns the Class object corresponding to this enum constant's enum type. | final int | hashCode() Returns a hash code for this enum constant. | final String | name() Returns the name of this enum constant, exactly as declared in its enum declaration. | final int | ordinal() Returns the ordinal of this enumeration constant (its position in its enum declaration, where the initial constant is assigned an ordinal of zero). | String | toString() Returns the name of this enum constant, as contained in the declaration. | static <T extends Enum<T>> T | valueOf(Class<T> enumClass, String name) Returns the enum constant of the specified enum class with the specified name. | |
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. | void | finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. | final Class<?> | getClass() Returns the runtime class of this Object. | int | hashCode() Returns a hash code value for the object. | final void | notify() Wakes up a single thread that is waiting on this object's monitor. | final void | notifyAll() Wakes up all threads that are waiting on this object's monitor. | String | toString() Returns a string representation of the object. | final void | wait(long timeoutMillis, int nanos) Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed. | final void | wait(long timeoutMillis) Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed. | final void | wait() Causes the current thread to wait until it is awakened, typically by being notified or interrupted. | |

Enum values
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
The singleton instance for the current era, 'Current Era', which has the numeric value 1.
Public methods
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.
| Returns |
|---|
int | the era value, from 0 (BCE) to 1 (CE) |
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 | int: the BCE/CE value to represent, from 0 (BCE) to 1 (CE) |
| Returns |
|---|
IsoEra | the era singleton, not null |
