wbuffer_convert class

Describes a stream buffer that controls the transmission of elements to and from a byte stream buffer.

Syntax

template <class Codecvt, class Elem = wchar_t, class Traits = std::char_traits<Elem>>
class wbuffer_convert
    : public std::basic_streambuf<Elem, Traits>

Parameters

Codecvt
The locale facet that represents the conversion object.

Elem
The wide-character element type.

Traits
The traits associated with Elem.

Remarks

This class template describes a stream buffer that controls the transmission of elements of type _Elem, whose character traits are described by the class Traits, to and from a byte stream buffer of type std::streambuf.

Conversion between a sequence of Elem values and multibyte sequences is performed by an object of class Codecvt<Elem, char, std::mbstate_t>, which meets the requirements of the standard code-conversion facet std::codecvt<Elem, char, std::mbstate_t>.

An object of this class template stores:

• A pointer to its underlying byte stream buffer.
• A pointer to an allocated conversion facet object, which is freed when the wbuffer_convert is destroyed.
