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


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.


// 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
