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.

Friends And Related Function Documentation

   template<typename _Facet > bool has_facet (const locale &)  throw () [friend]
       Test for the presence of a facet. has_facet tests the locale argument for the presence of
       the facet type provided as the template parameter. Facets derived from the facet parameter
       will also return true.

       Parameters:
           Facet The facet type to test the presence of.
           locale The locale to test.

       Returns:
           true if locale contains a facet of type Facet, else false.

   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.

       Parameters:
           Facet The facet type to access.
           locale The locale to use.

       Returns:
           Reference to facet of type Facet.

       Exceptions:
           std::bad_cast if locale doesn't contain a facet of type Facet.
