std::messages::~messages
From cppreference.com
| 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.
[edit] Example
Run this code
#include <iostream> #include <locale> struct Destructible_messages : public std::messages<wchar_t> { Destructible_messages(std::size_t refs = 0) : messages(refs) {} ~Destructible_messages() {}; // public dtor }; int main() { Destructible_messages dc; // std::messages<wchar_t> c; // compile error: protected destructor }
