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

Synopsis

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.

Example

// Run this code

#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
}
