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)
Filtering Mode | Language Priority List: "de-DE" |
Language Priority List: "de-*-DE" |
---|---|---|
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" .
|
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. |
IGNORE_EXTENDED_RANGES
|
Performs basic filtering and returns "de-DE" and
"de-DE-1996" .
|
Performs basic filtering and returns null because
nothing matches.
|
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" .
|
REJECT_EXTENDED_RANGES
|
Same as above. |
Throws IllegalArgumentException because "de-*-DE" is
not a valid basic language range.

Enum values
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
.
