Enum IDNA.Error

  • All Implemented Interfaces:
    Serializable, Comparable<IDNA.Error>
    Enclosing class:
    IDNA
    public static enum IDNA.Error
extends Enum<IDNA.Error>
    IDNA error bit set values. When a domain name or label fails a processing step or does not meet the validity criteria, then one or more of these error bits are set.
    Status:
    Stable ICU 4.6.

      • EMPTY_LABEL

        public static final IDNA.Error EMPTY_LABEL
        A non-final domain name label (or the whole domain name) is empty.
        Status:
        Stable ICU 4.6.

      • LABEL_TOO_LONG

        public static final IDNA.Error LABEL_TOO_LONG
        A domain name label is longer than 63 bytes. (See STD13/RFC1034 3.1. Name space specifications and terminology.) This is only checked in ToASCII operations, and only if the output label is all-ASCII.
        Status:
        Stable ICU 4.6.

      • DOMAIN_NAME_TOO_LONG

        public static final IDNA.Error DOMAIN_NAME_TOO_LONG
        A domain name is longer than 255 bytes in its storage form. (See STD13/RFC1034 3.1. Name space specifications and terminology.) This is only checked in ToASCII operations, and only if the output domain name is all-ASCII.
        Status:
        Stable ICU 4.6.

      • LEADING_HYPHEN

        public static final IDNA.Error LEADING_HYPHEN
        A label starts with a hyphen-minus ('-').
        Status:
        Stable ICU 4.6.

      • TRAILING_HYPHEN

        public static final IDNA.Error TRAILING_HYPHEN
        A label ends with a hyphen-minus ('-').
        Status:
        Stable ICU 4.6.

      • HYPHEN_3_4

        public static final IDNA.Error HYPHEN_3_4
        A label contains hyphen-minus ('-') in the third and fourth positions.
        Status:
        Stable ICU 4.6.

      • LEADING_COMBINING_MARK

        public static final IDNA.Error LEADING_COMBINING_MARK
        A label starts with a combining mark.
        Status:
        Stable ICU 4.6.

      • DISALLOWED

        public static final IDNA.Error DISALLOWED
        A label or domain name contains disallowed characters.
        Status:
        Stable ICU 4.6.

      • PUNYCODE

        public static final IDNA.Error PUNYCODE
        A label starts with "xn--" but does not contain valid Punycode. That is, an xn-- label failed Punycode decoding.
        Status:
        Stable ICU 4.6.

      • LABEL_HAS_DOT

        public static final IDNA.Error LABEL_HAS_DOT
        A label contains a dot=full stop. This can occur in an input string for a single-label function.
        Status:
        Stable ICU 4.6.

      • INVALID_ACE_LABEL

        public static final IDNA.Error INVALID_ACE_LABEL
        An ACE label does not contain a valid label string. The label was successfully ACE (Punycode) decoded but the resulting string had severe validation errors. For example, it might contain characters that are not allowed in ACE labels, or it might not be normalized.
        Status:
        Stable ICU 4.6.

      • BIDI

        public static final IDNA.Error BIDI
        A label does not meet the IDNA BiDi requirements (for right-to-left characters).
        Status:
        Stable ICU 4.6.

      • CONTEXTJ

        public static final IDNA.Error CONTEXTJ
        A label does not meet the IDNA CONTEXTJ requirements.
        Status:
        Stable ICU 4.6.

      • CONTEXTO_PUNCTUATION

        public static final IDNA.Error CONTEXTO_PUNCTUATION
        A label does not meet the IDNA CONTEXTO requirements for punctuation characters. Some punctuation characters "Would otherwise have been DISALLOWED" but are allowed in certain contexts. (RFC 5892)
        Status:
        Stable ICU 49.

      • CONTEXTO_DIGITS

        public static final IDNA.Error CONTEXTO_DIGITS
        A label does not meet the IDNA CONTEXTO requirements for digits. Arabic-Indic Digits (U+066x) must not be mixed with Extended Arabic-Indic Digits (U+06Fx).
        Status:
        Stable ICU 49.

    • Method Detail

      • values

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

      • valueOf

        public static IDNA.Error 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
