public abstract class AbstractI18nContentSupport
extends Object
implements I18nContentSupport

An abstract implementation of I18nContentSupport which stores the locale specific content in node data having a local suffix: <name>_<locale>. The detection of the current locale, based on the URI for instance, is left to the concrete implementation.

Field Detail

defaultLocale

protected Locale defaultLocale

If no locale can be determined the default locale will be set. If no default locale is defined the fallback locale is used.

public AbstractI18nContentSupport()

Method Detail

getLocale

public Locale getLocale()

Description copied from interface: I18nContentSupport

Get the current locale used for rendering content.

Specified by:

getLocale in interface I18nContentSupport

setLocale

public void setLocale(Locale locale)

Specified by:

setLocale in interface I18nContentSupport

getFallbackLocale

public Locale getFallbackLocale()

Description copied from interface: I18nContentSupport

The default locale to be used. Can be used to fix the system to a certain language.

Specified by:

getFallbackLocale in interface I18nContentSupport

setFallbackLocale

public void setFallbackLocale(Locale fallbackLocale)

Specified by:

setFallbackLocale in interface I18nContentSupport

getNextLocale

protected Locale getNextLocale(Locale locale)

Returns the closest locale for which isLocaleSupported(Locale) is true.

• If the locale has a country specified (fr_CH) the locale without country (fr) will be returned.
• If the locale has no country specified (fr) the first locale with the same language but specific country (fr_CH) will be returned.
• If this fails the fall-back locale is returned

Warning: if you have configured both (fr and fr_CH) this method will jiter between this two values.

determineLocale
