Parameters
Parameter |
Description |
|---|---|
Codecvt |
The locale facet that represents the conversion object. |
Elem |
The wide-character element type. |
Traits |
The traits associated with Elem. |
Remarks
This template class 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 template class stores:
A pointer to its underlying byte stream buffer
A pointer to the allocated conversion object (which is freed when the wbuffer_convert object is destroyed)
A conversion state object of type state_type.
