- All Implemented Interfaces:
- Serializable,- Comparable<IsoEra>,- Constable,- Era,- TemporalAccessor,- TemporalAdjuster
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.
- Implementation Requirements:
- This is an immutable and thread-safe enum.

Method Details- 
valuesReturns an array containing the constants of this enum class, in the order they are declared.- Returns:
- an array containing the constants of this enum class, in the order they are declared
 
- 
valueOfReturns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name
- NullPointerException- if the argument is null
 
- 
ofObtains an instance ofIsoErafrom anintvalue.IsoErais an enum representing the ISO eras of BCE/CE. This factory allows the enum to be obtained from theintvalue.- 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
 
- 
getValuepublic int getValue()Gets the numeric eraintvalue.The era BCE has the value 0, while the era CE has the value 1.
