IsoEra

Page Summary

• IsoEra represents an era in the ISO calendar system, defining 'Current Era' (CE) and 'Before Current Era' (BCE).

• Although ISO-8601 doesn't define eras, IsoEra provides them for years on or after 0001-01-01 (CE) and years before (BCE).

• It's crucial to use getValue() instead of ordinal() to get the numeric representation of an IsoEra.

• IsoEra has two enum values: BCE (value 0) and CE (value 1).

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.

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.

Inherited Method Summary

final Class<?>	getClass() Returns the unique instance of Class that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the wait() methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait(long timeout, int nanos) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
final void	wait(long timeout) Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object or until the specified timeout expires.
final void	wait() Causes the calling thread to wait until another thread calls the notify() or notifyAll() method of this object.
