枚举 HijrahEra

java.lang.Object

java.lang.Enum<HijrahEra>

java.time.chrono.HijrahEra

所有已实现的接口:

Serializable, Comparable<HijrahEra>, 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.

从以下版本开始:

1.8

枚举常量概要

枚举常量

枚举常量	说明
AH	The singleton instance for the current era, 'Anno Hegirae', which has the numeric value 1.

方法概要

限定符和类型	方法	说明
int	getValue()	Gets the numeric era int value.
static HijrahEra	of(int hijrahEra)	Obtains an instance of HijrahEra from an int value.
ValueRange	range(TemporalField field)	Gets the range of valid values for the specified field.
static HijrahEra	valueOf(String name)	返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)
static HijrahEra[]	values()	按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示: for (HijrahEra c : HijrahEra.values()) System.out.println(c);

枚举常量详细资料

AH

public static final HijrahEra AH

The singleton instance for the current era, 'Anno Hegirae', which has the numeric value 1.

方法详细资料

values

public static HijrahEra[] values()

按照声明该枚举类型的常量的顺序, 返回 包含这些常量的数组。该方法可用于迭代 常量, 如下所示:

for (HijrahEra c : HijrahEra.values())
    System.out.println(c);

返回:

按照声明该枚举类型的常量的顺序返回的包含这些常量的数组

valueOf

public static HijrahEra valueOf(String name)

返回带有指定名称的该类型的枚举常量。 字符串必须与用于声明该类型的枚举常量的 标识符完全匹配。(不允许有多余 的空格字符。)

参数:

name - 要返回的枚举常量的名称。

返回:

返回带有指定名称的枚举常量

抛出:

IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量

NullPointerException - 如果参数为空值

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

参数:

hijrahEra - the era to represent, only 1 supported

返回:

the HijrahEra.AH singleton, not null

抛出:

DateTimeException - if the value is invalid

getValue

public int getValue()

Gets the numeric era int value.

The era AH has the value 1.

指定者:

getValue 在接口中 Era

返回:

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.

指定者:

range 在接口中 Era

指定者:

range 在接口中 TemporalAccessor

参数:

field - the field to query the range for, not null

返回:

the range of valid values for the field, not null

抛出:

DateTimeException - if the range for the field cannot be obtained

UnsupportedTemporalTypeException - if the unit is not supported
