std::time_put<CharT,OutputIt>::~time_put

From cppreference.com
< cpp‎ | locale‎ | time put
 
 
 
 
Defined in header <locale>
protected: ~time_put();

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

[edit] Example

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