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.

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.

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

public Locale determineLocale()

Extracts the language from the uri.

Specified by:

determineLocale in interface I18nContentSupport

onDetermineLocale

protected abstract Locale onDetermineLocale()

determineLocalFromString

protected static Locale determineLocalFromString(String localeStr)

toI18NURI

public String toI18NURI(String uri)

Description copied from interface: I18nContentSupport

Transform the internal uri to a i18n uri. This method may add a prefix or suffix

Specified by:

toI18NURI in interface I18nContentSupport

toI18NURI

protected abstract String toI18NURI(String uri,
                                    Locale locale)

toRawURI

public String toRawURI(String i18nURI)

Removes the prefix.

Specified by:

toRawURI in interface I18nContentSupport

toRawURI

protected abstract String toRawURI(String i18nURI,
                                   Locale locale)

getNodeData

public NodeData getNodeData(Content node,
                            String name,
                            Locale locale)
                     throws javax.jcr.RepositoryException

Description copied from interface: I18nContentSupport

Returns the NodeData object based on the language passes.

Specified by:

getNodeData in interface I18nContentSupport

Throws:

javax.jcr.RepositoryException

getNodeData

public NodeData getNodeData(Content node,
                            String name)

Returns the nodedata with the name <name>_<current language> or <name>_<fallback language> otherwise returns <name>.

Specified by:

getNodeData in interface I18nContentSupport

getNode

public javax.jcr.Node getNode(javax.jcr.Node node,
                              String name)
                       throws javax.jcr.RepositoryException

Specified by:

getNode in interface I18nContentSupport

Throws:

javax.jcr.RepositoryException

getNextContentLocale

protected Locale getNextContentLocale(Locale locale,
                                      Set<Locale> checkedLocales)

Uses getNextLocale(Locale) to find the next locale. If the returned locale is in the checkedLocales set it falls back to the fall-back locale. If the fall-back locale itself is passed to the method, the method returns null to signal the end of the chain.

isEnabled

public boolean isEnabled()

Specified by:

isEnabled in interface I18nContentSupport

setEnabled

public void setEnabled(boolean enabled)

getLocales

public Collection<Locale> getLocales()

Description copied from interface: I18nContentSupport

Returns the available locales.

Specified by:

getLocales in interface I18nContentSupport

addLocale

public void addLocale(LocaleDefinition ld)

isLocaleSupported

protected boolean isLocaleSupported(Locale locale)

isEmpty

protected boolean isEmpty(NodeData nd)

Checks if the nodedata field is empty.

getDefaultLocale
