Constructor & Destructor Documentation
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 = new _Codecvt()) [inline], [explicit]
Default constructor.
Parameters:
-
__pcvt The facet to use for conversions.
Takes ownership of __pcvt and will delete it in the destructor.
Definition at line 184 of file locale_conv.h.
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.

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 (const byte_string & __byte_err, const wide_string & __wide_err = wide_string()) [inline], [explicit]
Construct with error strings.
Parameters:
-
__byte_err A string to return on failed conversions.
__wide_err A wide string to return on failed conversions.
