Method Detail

toLocale

public Locale toLocale(String localeName)

Description copied from interface: LocalizationSetter

Converts a locale name into a Locale. The result is cached.

Specified by:

toLocale in interface LocalizationSetter

setLocaleFromLocaleName

public boolean setLocaleFromLocaleName(String localeName)

Description copied from interface: LocalizationSetter

Determines if the provided potential locale name (presumably, extracted from a request URL) is a supported locale name. A call to this method will always set the ThreadLocale (either to the provided locale, if supported, or to the default locale). If the locale name is supported, it will also set the PersistentLocale (which may affect how page and event links are generated, to persist the selected locale across requests). Note that locale names are case sensitive.

Specified by:

setLocaleFromLocaleName in interface LocalizationSetter

Parameters:

localeName - name of locale to check (which may be blank or not a locale name)

Returns:

true if the locale name is supported and the PersistentLocale was set

setNonPersistentLocaleFromLocaleName

public void setNonPersistentLocaleFromLocaleName(String localeName)

Description copied from interface: LocalizationSetter

Allows the locale to be set from a specified locale name (which may be narrowed or defaulted to a support locale). Does not set the persistent locale.

Specified by:

setNonPersistentLocaleFromLocaleName in interface LocalizationSetter

Parameters:

localeName - locale in effect for this request

getSupportedLocales

public List<Locale> getSupportedLocales()

Description copied from interface: LocalizationSetter

Returns a list of supported locales, as per the SymbolConstants.SUPPORTED_LOCALES symbol.

Specified by:

getSupportedLocales in interface LocalizationSetter

isSupportedLocaleName

public boolean isSupportedLocaleName(String localeName)

Description copied from interface: LocalizationSetter

Checks to see if the indicated locale name is a supported locale name (that may have been incorporated into a request path). This is an important part of decoding a request.

Specified by:

isSupportedLocaleName in interface LocalizationSetter

getSupportedLocalesModel

public SelectModel getSupportedLocalesModel()

Description copied from interface: LocalizationSetter

Returns the supported locales packaged as a model. The label for each locale comes from Locale.getDisplayName(Locale) (in that locale).

Specified by:

getSupportedLocalesModel in interface LocalizationSetter
