std::codecvt<InternT,ExternT,State>::~codecvt - std::codecvt<InternT,ExternT,State>::~codecvt


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.


// 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
