function PluginBase::queryLanguageSubstitutions

Returns substitutions for Views queries for languages.

This is needed so that the language options returned by PluginBase::listLanguages() are able to be used in queries. It is called by the Views module implementation of hook_views_query_substitutions() to get the language-related substitutions.

Return value

array An array in the format of hook_views_query_substitutions() that gives the query substitutions needed for the special language types.
