Enum AccountingEra

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<AccountingEra>, java.time.chrono.Era, java.time.temporal.TemporalAccessor, java.time.temporal.TemporalAdjuster

    public enum AccountingEra
    extends java.lang.Enum<AccountingEra>
    implements java.time.chrono.Era
    An era in the Accounting calendar system.

    The Accounting calendar system has two eras. The current era, for years from 1 onwards, is known as the '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 accounting epochs 0001-01-01 (Accounting) will vary against the ISO calendar. Depending on options chosen, it can start as early as 0000-01-26 (ISO) or as late as 0001-01-04 (ISO).

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

    Implementation Requirements:

    This is an immutable and thread-safe enum.

      • values

        public static AccountingEra[] 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 (AccountingEra c : AccountingEra.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static AccountingEra valueOf​(java.lang.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:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
      • of

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

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

        Parameters:
        era - the BCE/CE value to represent, from 0 (BCE) to 1 (CE)
        Returns:
        the era singleton, not null
        Throws:
        java.time.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 java.time.chrono.Era
        Returns:
        the era value, from 0 (BCE) to 1 (CE)
