std::codecvt::~codecvt
From cppreference.com
| Defined in header <locale>
|
||
| protected: ~codecvt(); |
||
Destructs a std::codecvt facet. This destructor is protected and virtual (due to base class destructor being virtual). An object of type std::codecvt, like most facets, can only be destroyed when the last std::locale object that implements this facet goes out of scope or if a user-defined class is derived from std::codecvt and implements a public destructor.
Example
Run this code
#include <iostream> #include <locale> struct Destructible_codecvt : public std::codecvt<wchar_t, char, std::mbstate_t> { Destructible_codecvt(std::size_t refs = 0) : codecvt(refs) {} // note: the implicit destructor is public }; int main() { Destructible_codecvt dc; // std::codecvt<wchar_t> c; // compile error: protected destructor }
