std::num_get<CharT,InputIt>::~num_get (3) - Linux Man Pages

std::num_get<CharT,InputIt>::~num_get: std::num_get<CharT,InputIt>::~num_get

NAME

std::num_get<CharT,InputIt>::~num_get - std::num_get<CharT,InputIt>::~num_get

Synopsis


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


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

Example


// Run this code


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