Enum PaxEra

  • All Implemented Interfaces:
    Serializable, Comparable<PaxEra>, Era, TemporalAccessor, TemporalAdjuster

    public enum PaxEra
    extends Enum<PaxEra>
    implements Era
    An era in the Pax calendar system.

    The Pax calendar system has two eras. The current era, for years from 1 onwards, is known as 'Current Era'. All previous years, zero or earlier in the proleptic count or one and greater in the year-of-era count, are part of the 'Before Current Era' era.

    The start of the Pax epoch 0001-01-01 (Pax) is 0000-12-31 (ISO).

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

    Implementation Requirements:

    This is an immutable and thread-safe enum.
    • Enum Constant Detail

      • BCE

        public static final PaxEra BCE
        The singleton instance for the era before the current one, 'Before Current Era', which has the numeric value 0.
      • CE

        public static final PaxEra CE
        The singleton instance for the current era, 'Current Era', which has the numeric value 1.
    • Method Detail

      • values

        public static PaxEra[] 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 (PaxEra c : PaxEra.values())
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static PaxEra 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.)
        name - the name of the enum constant to be returned.
        the enum constant with the specified name
        IllegalArgumentException - if this enum type has no constant with the specified name
        NullPointerException - if the argument is null
      • of

        public static PaxEra of​(int era)
        Obtains an instance of PaxEra from an int value.

        PaxEra is an enum representing the Pax eras of BCE/CE. This factory allows the enum to be obtained from the int value.

        era - the BCE/CE value to represent, from 0 (BCE) to 1 (CE)
        the era singleton, not null
        DateTimeException - if the value is invalid
      • getValue

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

        The era BCE has the value 0, while the era CE has the value 1.

        Specified by:
        getValue in interface Era
        the era value, from 0 (BCE) to 1 (CE)
