std::numpunct<CharT>::~numpunct - std::numpunct<CharT>::~numpunct


Defined in header <locale>
protected: ~numpunct();

Destructs a std::numpunct facet. This destructor is protected and virtual (due to base_class destructor being virtual). An object of type std::numpunct, 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::numpunct and implements a public destructor.


// Run this code

  #include <iostream>
  #include <locale>
  struct Destructible_numpunct : public std::numpunct<wchar_t>
      Destructible_numpunct(std::size_t refs = 0) : numpunct(refs) {}
      // note: the implicit destructor is public
  int main()
      Destructible_numpunct dc;
      // std::numpunct<wchar_t> c; // compile error: protected destructor
