std::messages<CharT>::~messages - std::messages<CharT>::~messages


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

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


// Run this code

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