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.

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.
_Facet | The facet type to test the presence of. |
__loc | The locale to test. |
__loc
contains a facet of type _Facet, else false. Definition at line 178 of file locale_classes.tcc.

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.
_Facet | The facet type to access. |
__loc | The locale to use. |
std::bad_cast | if __loc doesn't contain a facet of type _Facet. |
