Detailed Description

Classes and functions for internationalization and localization.

Function Documentation

template<typename _Facet >

bool std::has_facet	(	const locale &	__loc	)
throw	(
	)

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.

Template Parameters

_Facet

The facet type to test the presence of.

Parameters

__loc

The locale to test.

Returns

true if __loc contains a facet of type _Facet, else false.

template<typename _Facet >

const _Facet & std::use_facet

(

const locale &

__loc

)

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.

Template Parameters

_Facet

The facet type to access.

Parameters

__loc

The locale to use.

Returns

Reference to facet of type Facet.

Exceptions

std::bad_cast

if __loc doesn't contain a facet of type _Facet.
