Défini dans l'entête <locale>
class locale::id;

Le std::locale::id classe fournit l'implémentation spécifique d'identification d'une facette locale. Chaque classe dérivée de std::locale::facet doit avoir un membre statique public d'std::locale::id type et chaque objet std::locale maintient une liste de facettes qu'elle met en œuvre, indexés par leurs ids .

Original:

The class std::locale::id provides implementation-specific identification of a locale facet. Each class derived from std::locale::facet must have a public static member of type std::locale::id and each std::locale object maintains a list of facets it implements, indexed by their ids.
