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
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 }
