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