std::time_get<CharT,InputIt>::~time_get
From cppreference.com
Defined in header <locale> | ||
protected: ~time_get(); | ||
Destructs a std::time_get facet. This destructor is protected and virtual (due to base class destructor being virtual). An object of type std::time_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::time_get and implements a public destructor.
[edit]Example
Run this code
#include <iostream>#include <locale> struct Destructible_time_get :publicstd::time_get<wchar_t>{ Destructible_time_get(std::size_t refs =0): time_get(refs){}// note: the implicit destructor is public}; int main(){ Destructible_time_get dc;// std::time_get<wchar_t> c; // compile error: protected destructor}
