Detailed Description

  template<typename _Codecvt, typename _Elem = wchar_t, typename _Wide_alloc = allocator<_Elem>, typename _Byte_alloc = allocator<char>>
class std::wstring_convert< _Codecvt, _Elem, _Wide_alloc, _Byte_alloc >"String conversions.

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 () [inline]

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.

  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.
