Package com.ibm.icu.text
Enum IDNA.Error
- All Implemented Interfaces:
Serializable
,Comparable<IDNA.Error>
,java.lang.constant.Constable
- Enclosing class:
IDNA
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.

Enum Constant Details
-
EMPTY_LABEL
A non-final domain name label (or the whole domain name) is empty. -
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. -
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. -
LEADING_HYPHEN
A label starts with a hyphen-minus ('-'). -
TRAILING_HYPHEN
A label ends with a hyphen-minus ('-'). -
HYPHEN_3_4
A label contains hyphen-minus ('-') in the third and fourth positions. -
LEADING_COMBINING_MARK
A label starts with a combining mark. -
DISALLOWED
A label or domain name contains disallowed characters. -
PUNYCODE
A label starts with "xn--" but does not contain valid Punycode. That is, an xn-- label failed Punycode decoding. -
LABEL_HAS_DOT
A label contains a dot=full stop. This can occur in an input string for a single-label function. -
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. -
BIDI
A label does not meet the IDNA BiDi requirements (for right-to-left characters). -
CONTEXTJ
A label does not meet the IDNA CONTEXTJ requirements. -
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) -
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).
