getLanguageAlternative

@Nullable
@Nullable Page getLanguageAlternative(@NotNull
                                                @NotNull Page page,
                                                @NotNull
                                                @NotNull java.util.Locale locale)

Returns the language alternative of a given Page in the given Locale.

This is an optimised implementation of

  languageAlternativesService.getLanguageAlternative(page).get(locale);
  

Parameters:

page - the Page

locale - the Locale

Returns:

a Page with the same relative path to the site root as the given Page but in the given Locale, or null if it does not exist.

getLanguageAlternatives

@NotNull
@NotNull java.util.Map<java.util.Locale,Page> getLanguageAlternatives(@NotNull
                                                                               @NotNull Page page)

Traverses the site subtree of the given Page using depth-first-search up to a configured maximum depth and returns language alternatives of the given page in each of the found language roots in the subtree. Language roots that are ancestors of other language roots are skipped. For example /content/wknd/fr/fr is taking precedence over /content/wknd/fr for which Locale derived from the path would be the same.

The Page's site root is defined by an implementation of SiteRootSelectionStrategy.getSiteRoot(Page).

Parameters:

page - the given Page to return language alternatives for

Returns:

a Collection of all language alternatives within the Page's site root
