Constructor Details

LikelySubtags

private LikelySubtags(LikelySubtags.Data data)

Method Details

canonicalize

public ULocale canonicalize(ULocale locale)

Implementation of LocaleMatcher.canonicalize(ULocale).

getCanonical

private static String getCanonical(Map<String,String> aliases,
 String alias)

makeMaximizedLsrFrom

public LSR makeMaximizedLsrFrom(ULocale locale,
 boolean returnInputIfUnmatch)

makeMaximizedLsrFrom

public LSR makeMaximizedLsrFrom(Locale locale)

makeMaximizedLsr

private LSR makeMaximizedLsr(String language,
 String script,
 String region,
 String variant,
 boolean returnInputIfUnmatch)

isMacroregion

private boolean isMacroregion(String region)

Helper method to find out a region is a macroregion

maximize

private LSR maximize(String language,
 String script,
 String region,
 boolean returnInputIfUnmatch)

Raw access to addLikelySubtags. Input must be in canonical format, eg "en", not "eng" or "EN".

compareLikely

int compareLikely(LSR lsr,
 LSR other,
 int likelyInfo)

Tests whether lsr is "more likely" than other. For example, fr-Latn-FR is more likely than fr-Latn-CH because FR is the default region for fr-Latn.

The likelyInfo caches lookup information between calls. The return value is an updated likelyInfo value, with bit 0 set if lsr is "more likely". The initial value of likelyInfo must be negative.

getLikelyIndex

private int getLikelyIndex(String language,
 String script)

trieNext

private static final int trieNext(BytesTrie iter,
 String s,
 int i)

minimizeSubtags

public LSR minimizeSubtags(String languageIn,
 String scriptIn,
 String regionIn,
 ULocale.Minimize fieldToFavor)

getTable

private Map<String,LSR> getTable()

toString

public String toString()

Overrides:
