IDNA.Error

java.lang.Object
- java.lang.Enum<IDNA.Error>
- - ohos.global.icu.text.IDNA.Error

所有已实现的接口:

Serializable, Comparable<IDNA.Error>

封闭类:

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.

枚举常量概要

枚举常量
枚举常量	说明
`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_DIGITS`	A label does not meet the IDNA CONTEXTO requirements for digits.
`CONTEXTO_PUNCTUATION`	A label does not meet the IDNA CONTEXTO requirements for punctuation characters.
`DISALLOWED`	A label or domain name contains disallowed characters.
`DOMAIN_NAME_TOO_LONG`	A domain name is longer than 255 bytes in its storage form.
`EMPTY_LABEL`	A non-final domain name label (or the whole domain name) is empty.
`HYPHEN_3_4`	A label contains hyphen-minus ('-') in the third and fourth positions.
`INVALID_ACE_LABEL`	An ACE label does not contain a valid label string.
`LABEL_HAS_DOT`	A label contains a dot=full stop.
`LABEL_TOO_LONG`	A domain name label is longer than 63 bytes.
`LEADING_COMBINING_MARK`	A label starts with a combining mark.
`LEADING_HYPHEN`	A label starts with a hyphen-minus ('-').
`PUNYCODE`	A label starts with "xn--" but does not contain valid Punycode.
`TRAILING_HYPHEN`	A label ends with a hyphen-minus ('-').

方法概要

所有方法静态方法具体方法
限定符和类型	方法	说明
`static IDNA.Error`	`valueOf(String name)`	返回带有指定名称的该类型的枚举常量。字符串必须与用于声明该类型的枚举常量的标识符完全匹配。(不允许有多余的空格字符。)
`static IDNA.Error[]`	`values()`	按照声明该枚举类型的常量的顺序, 返回包含这些常量的数组。该方法可用于迭代常量, 如下所示: for (IDNA.Error c : IDNA.Error.values()) System.out.println(c);

  - EMPTY_LABEL
```
public static final IDNA.Error EMPTY_LABEL
```
    A non-final domain name label (or the whole domain name) is empty.
  - 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.
  - 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.
  - LEADING_HYPHEN
```
public static final IDNA.Error LEADING_HYPHEN
```
    A label starts with a hyphen-minus ('-').
  - TRAILING_HYPHEN
```
public static final IDNA.Error TRAILING_HYPHEN
```
    A label ends with a hyphen-minus ('-').
  - HYPHEN_3_4
```
public static final IDNA.Error HYPHEN_3_4
```
    A label contains hyphen-minus ('-') in the third and fourth positions.
  - LEADING_COMBINING_MARK
```
public static final IDNA.Error LEADING_COMBINING_MARK
```
    A label starts with a combining mark.
  - DISALLOWED
```
public static final IDNA.Error DISALLOWED
```
    A label or domain name contains disallowed characters.
  - 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.
  - 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.
  - 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.
  - BIDI
```
public static final IDNA.Error BIDI
```
    A label does not meet the IDNA BiDi requirements (for right-to-left characters).
  - CONTEXTJ
```
public static final IDNA.Error CONTEXTJ
```
    A label does not meet the IDNA CONTEXTJ requirements.
  - 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)
  - 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).

  - values
```
public static IDNA.Error[] values()
```
    按照声明该枚举类型的常量的顺序, 返回包含这些常量的数组。该方法可用于迭代常量, 如下所示:
```
for (IDNA.Error c : IDNA.Error.values())
    System.out.println(c);
```
    返回:
    
    按照声明该枚举类型的常量的顺序返回的包含这些常量的数组
  - valueOf
```
public static IDNA.Error valueOf(String name)
```
    返回带有指定名称的该类型的枚举常量。字符串必须与用于声明该类型的枚举常量的标识符完全匹配。(不允许有多余的空格字符。)
    
    参数:
    
    name - 要返回的枚举常量的名称。
    
    返回:
    
    返回带有指定名称的枚举常量
    
    抛出:
    
    IllegalArgumentException - 如果该枚举类型没有带有指定名称的常量
    
    NullPointerException - 如果参数为空值
