Enum HijrahEra

  • All Implemented Interfaces:
    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.

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

    • Enum Constant Detail

      • AH

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

    • Method Detail

      • values

        public static HijrahEra[] values​()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (HijrahEra c : HijrahEra.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static HijrahEra valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type 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
