NAME
std::locale::id -
SYNOPSIS
Detailed Description
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.

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.
