枚举 Locale.FilteringMode

java.lang.Object

java.lang.Enum<Locale.FilteringMode>

java.util.Locale.FilteringMode

所有已实现的接口:

Serializable, Comparable<Locale.FilteringMode>

封闭类:

Locale

public static enum Locale.FilteringMode
extends Enum<Locale.FilteringMode>

This enum provides constants to select a filtering mode for locale matching. Refer to RFC 4647 Matching of Language Tags for details.

As an example, think of two Language Priority Lists each of which includes only one language range and a set of following language tags:

    de (German)
    de-DE (German, Germany)
    de-Deva (German, in Devanagari script)
    de-Deva-DE (German, in Devanagari script, Germany)
    de-DE-1996 (German, Germany, orthography of 1996)
    de-Latn-DE (German, in Latin script, Germany)
    de-Latn-DE-1996 (German, in Latin script, Germany, orthography of 1996)
 

The filtering method will behave as follows:

Filtering Mode	Language Priority List: "de-DE"	Language Priority List: "de-*-DE"
FilteringMode#AUTOSELECT_FILTERING	Performs basic filtering and returns "de-DE" and "de-DE-1996".	Performs extended filtering and returns "de-DE", "de-Deva-DE", "de-DE-1996", "de-Latn-DE", and "de-Latn-DE-1996".
FilteringMode#EXTENDED_FILTERING	Performs extended filtering and returns "de-DE", "de-Deva-DE", "de-DE-1996", "de-Latn-DE", and "de-Latn-DE-1996".	Same as above.
FilteringMode#IGNORE_EXTENDED_RANGES	Performs basic filtering and returns "de-DE" and "de-DE-1996".	Performs basic filtering and returns null because nothing matches.
FilteringMode#MAP_EXTENDED_RANGES	Same as above.	Performs basic filtering and returns "de-DE" and "de-DE-1996" because "de-*-DE" is mapped to "de-DE".
FilteringMode#REJECT_EXTENDED_RANGES	Same as above.	Throws IllegalArgumentException because "de-*-DE" is not a valid basic language range.

枚举常量概要

枚举常量

枚举常量	说明
AUTOSELECT_FILTERING	Specifies automatic filtering mode based on the given Language Priority List consisting of language ranges.
EXTENDED_FILTERING	Specifies extended filtering.
IGNORE_EXTENDED_RANGES	Specifies basic filtering: Note that any extended language ranges included in the given Language Priority List are ignored.
MAP_EXTENDED_RANGES	Specifies basic filtering: If any extended language ranges are included in the given Language Priority List, they are mapped to the basic language range.
REJECT_EXTENDED_RANGES	Specifies basic filtering: If any extended language ranges are included in the given Language Priority List, the list is rejected and the filtering method throws IllegalArgumentException.

方法概要

限定符和类型	方法	说明
static Locale.FilteringMode	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 Locale.FilteringMode[]	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 (Locale.FilteringMode c : Locale.FilteringMode.values()) System.out.println(c);

枚举常量详细资料

AUTOSELECT_FILTERING

public static final Locale.FilteringMode AUTOSELECT_FILTERING

Specifies automatic filtering mode based on the given Language Priority List consisting of language ranges. If all of the ranges are basic, basic filtering is selected. Otherwise, extended filtering is selected.

EXTENDED_FILTERING

public static final Locale.FilteringMode EXTENDED_FILTERING

Specifies extended filtering.

IGNORE_EXTENDED_RANGES

public static final Locale.FilteringMode IGNORE_EXTENDED_RANGES

Specifies basic filtering: Note that any extended language ranges included in the given Language Priority List are ignored.

MAP_EXTENDED_RANGES

public static final Locale.FilteringMode MAP_EXTENDED_RANGES

Specifies basic filtering: If any extended language ranges are included in the given Language Priority List, they are mapped to the basic language range. Specifically, a language range starting with a subtag "*" is treated as a language range "*". For example, "*-US" is treated as "*". If "*" is not the first subtag, "*" and extra "-" are removed. For example, "ja-*-JP" is mapped to "ja-JP".

REJECT_EXTENDED_RANGES

public static final Locale.FilteringMode REJECT_EXTENDED_RANGES

Specifies basic filtering: If any extended language ranges are included in the given Language Priority List, the list is rejected and the filtering method throws IllegalArgumentException.

方法详细资料

values

public static Locale.FilteringMode[] 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 (Locale.FilteringMode c : Locale.FilteringMode.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 Locale.FilteringMode 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
