Enclosing class:

ICULocaleService

public static class ICULocaleService.LocaleKey
extends ICUService.Key

A subclass of Key that implements a locale fallback mechanism. The first locale to search for is the locale provided by the client, and the fallback locale to search for is the current default locale. If a prefix is present, the currentDescriptor includes it before the locale proper, separated by "/". This is the default key instantiated by ICULocaleService.

Canonicalization adjusts the locale string so that the section before the first understore is in lower case, and the rest is in upper case, with no trailing underscores.

Constructor Details

LocaleKey

protected LocaleKey(String primaryID,
 String canonicalPrimaryID,
 String canonicalFallbackID,
 int kind)

PrimaryID is the user's requested locale string, canonicalPrimaryID is this string in canonical form, fallbackID is the current default locale's string in canonical form.

Method Details

createWithCanonicalFallback

public static ICULocaleService.LocaleKey createWithCanonicalFallback(String primaryID,
 String canonicalFallbackID)

Create a LocaleKey with canonical primary and fallback IDs.

createWithCanonicalFallback

public static ICULocaleService.LocaleKey createWithCanonicalFallback(String primaryID,
 String canonicalFallbackID,
 int kind)

Create a LocaleKey with canonical primary and fallback IDs.

createWithCanonical

public static ICULocaleService.LocaleKey createWithCanonical(ULocale locale,
 String canonicalFallbackID,
 int kind)

Create a LocaleKey with canonical primary and fallback IDs.

prefix

public String prefix()

Return the prefix associated with the kind, or null if the kind is KIND_ANY.

kind

public int kind()

Return the kind code associated with this key.

canonicalID

public String canonicalID()

Return the (canonical) original ID.

Overrides:

canonicalID in class ICUService.Key

currentID

public String currentID()

Return the (canonical) current ID, or null if no current id.

Overrides:

currentID in class ICUService.Key

currentDescriptor

public String currentDescriptor()

Return the (canonical) current descriptor, or null if no current id. Includes the keywords, whereas the ID does not include keywords.

Overrides:

currentDescriptor in class ICUService.Key

canonicalLocale

public ULocale canonicalLocale()

Convenience method to return the locale corresponding to the (canonical) original ID.

currentLocale

public ULocale currentLocale()

Convenience method to return the ulocale corresponding to the (canonical) currentID.

fallback

public boolean fallback()

If the key has a fallback, modify the key and return true, otherwise return false.

First falls back through the primary ID, then through the fallbackID. The final fallback is "" (root) unless the primary id was "" (root), in which case there is no fallback.

Overrides:

fallback in class ICUService.Key

isFallbackOf

public boolean isFallbackOf(String id)

If a key created from id would eventually fallback to match the canonical ID of this key, return true.

Overrides:

isFallbackOf in class ICUService.Key
