bool has_facet (const locale & __loc) 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.
Definition at line 88 of file locale_facets.tcc.
const _Facet& use_facet (const locale & __loc) [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.
