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