Enum SignStyle

  • All Implemented Interfaces:
    Serializable, Comparable<SignStyle>


    public enum SignStyle
    extends Enum<SignStyle>
    Enumeration of ways to handle the positive/negative sign.

    The formatting engine allows the positive and negative signs of numbers to be controlled using this enum. See DateTimeFormatterBuilder for usage.

    Implementation Requirements:
    This is an immutable and thread-safe enum.
    Since:
    1.8
    • Enum Constant Detail

      • NORMAL

        public static final SignStyle NORMAL
        Style to output the sign only if the value is negative.

        In strict parsing, the negative sign will be accepted and the positive sign rejected. In lenient parsing, any sign will be accepted.

      • ALWAYS

        public static final SignStyle ALWAYS
        Style to always output the sign, where zero will output '+'.

        In strict parsing, the absence of a sign will be rejected. In lenient parsing, any sign will be accepted, with the absence of a sign treated as a positive number.

      • NEVER

        public static final SignStyle NEVER
        Style to never output sign, only outputting the absolute value.

        In strict parsing, any sign will be rejected. In lenient parsing, any sign will be accepted unless the width is fixed.

      • NOT_NEGATIVE

        public static final SignStyle NOT_NEGATIVE
        Style to block negative values, throwing an exception on printing.

        In strict parsing, any sign will be rejected. In lenient parsing, any sign will be accepted unless the width is fixed.

      • EXCEEDS_PAD

        public static final SignStyle EXCEEDS_PAD
        Style to always output the sign if the value exceeds the pad width. A negative value will always output the '-' sign.

        In strict parsing, the sign will be rejected unless the pad width is exceeded. In lenient parsing, any sign will be accepted, with the absence of a sign treated as a positive number.

    • Method Detail

      • values

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

        public static SignStyle 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
