template<typename Facet>

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 85 of file locale_facets.tcc.

template<typename Facet>

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.
