Detailed Description¶

Facet ID class. The ID class provides facets with an index used to identify them. Every facet class must define a public static member locale::id, or be derived from a facet that provides this member, otherwise the facet cannot be used in a locale. The locale::id ensures that each class type gets a unique identifier. Definition at line 438 of file locale_classes.h.

template<typename _Facet > bool has_facet (const locale &) throw () [friend]¶

template<typename _Facet > const _Facet& use_facet (const locale &) [friend]¶

Return a facet. use_facet looks for and returns a reference to a facet of type Facet where Facet is the template parameter. If has_facet(locale) is true, there is a suitable facet to return. It throws std::bad_cast if the locale doesn't contain a facet of type Facet. Template Parameters: Parameters: Returns: Exceptions: Definition at line 130 of file locale_classes.tcc.
