Default constructor.

template<typename _Codecvt , typename _Elem = wchar_t, typename _Wide_alloc = allocator<_Elem>, typename _Byte_alloc = allocator<char>> std::wstring_convert< _Codecvt, _Elem, _Wide_alloc, _Byte_alloc >::wstring_convert (_Codecvt * __pcvt) [inline], [explicit]

Constructor.

Parameters

__pcvt The facet to use for conversions.

Takes ownership of __pcvt and will delete it in the destructor.

Definition at line 280 of file locale.

template<typename _Codecvt , typename _Elem = wchar_t, typename _Wide_alloc = allocator<_Elem>, typename _Byte_alloc = allocator<char>> std::wstring_convert< _Codecvt, _Elem, _Wide_alloc, _Byte_alloc >::wstring_convert (_Codecvt * __pcvt, state_type __state) [inline]

Construct with an initial converstion state.

Parameters

__pcvt The facet to use for conversions.
__state Initial conversion state.

Takes ownership of __pcvt and will delete it in the destructor. The object's conversion state will persist between conversions.

Construct with error strings.

Parameters

__byte_err A string to return on failed conversions.
__wide_err A wide string to return on failed conversions.
