# Enum Class HijrahEra

java.lang.Object
java.lang.Enum<HijrahEra>
java.time.chrono.HijrahEra

All Implemented Interfaces:
  `Serializable`, `Comparable<HijrahEra>`, `Constable`, `Era`, `TemporalAccessor`, `TemporalAdjuster`

public enum HijrahEra extends Enum<HijrahEra> implements Era
An era in the Hijrah calendar system.

The Hijrah calendar system has only one era covering the proleptic years greater than zero.

Do not use `ordinal()` to obtain the numeric representation of `HijrahEra`. Use `getValue()` instead.

Implementation Requirements:
  This is an immutable and thread-safe enum.
Since:
  1.8

## Enum Constant Details

### AH

public static final HijrahEra AH
The singleton instance for the current era, 'Anno Hegirae', which has the numeric value 1.

## Method Details

### values

public static HijrahEra[] values()
Returns 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

### valueOf

public static HijrahEra valueOf(String name)
Returns 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

### of

public static HijrahEra of(int hijrahEra)
Obtains an instance of `HijrahEra` from an `int` value.

The current era, which is the only accepted value, has the value 1

Parameters:
  `hijrahEra` - the era to represent, only 1 supported
Returns:
  the HijrahEra.AH singleton, not null
Throws:
  `DateTimeException` - if the value is invalid

### getValue

public int getValue()
Gets the numeric era `int` value.

The era AH has the value 1.

Specified by:
  `getValue` in interface `Era`
Returns:
  the era value, 1 (AH)

### range

public ValueRange range(TemporalField field)
Gets the range of valid values for the specified field.

The range object expresses the minimum and maximum valid values for a field. This era is used to enhance the accuracy of the returned range. If it is not possible to return the range, because the field is not supported or for some other reason, an exception is thrown.

If the field is a `ChronoField` then the query is implemented here. The `ERA` field returns the range. All other `ChronoField` instances will throw an `UnsupportedTemporalTypeException`.

If the field is not a `ChronoField`, then the result of this method is obtained by invoking `TemporalField.rangeRefinedBy(TemporalAccessor)` passing `this` as the argument. Whether the range can be obtained is determined by the field.

The `ERA` field returns a range for the one valid Hijrah era.

Specified by:
  `range` in interface `Era`
Specified by:
  `range` in interface `TemporalAccessor`
Parameters:
  `field` - the field to query the range for, not null
Returns:
  the range of valid values for the field, not null
Throws:
  `DateTimeException` - if the range for the field cannot be obtained
  `UnsupportedTemporalTypeException` - if the unit is not supported

### getDisplayName

public String getDisplayName(TextStyle style, Locale locale)
Gets the textual representation of this era.

This returns the textual name used to identify the era, suitable for presentation to the user. The parameters control the style of the returned text and the locale.

If no textual mapping is found then the `numeric value` is returned.

Specified by:
  `getDisplayName` in interface `Era`
Parameters:
  `style` - the style of the text required, not null
  `locale` - the locale to use, not null
Returns:
  the text value of the era, not null
