std::codecvt<InternT,ExternT,StateT>::~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.
[edit]Example
Run this code
#include <iostream>#include <locale> struct Destructible_codecvt :publicstd::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}
