NAME¶

std::num_get::~num_get - std::num_get::~num_get

Synopsis¶

Defined in header <locale>
protected: ~num_get();

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

Example¶

// Run this code

#include <iostream>
#include <locale>

struct Destructible_num_get : public std::num_get<wchar_t>
{
Destructible_num_get(std::size_t refs = 0) : num_get(refs) {}
// note: the implicit destructor is public
};

int main()
{
Destructible_num_get dc;
// std::num_get<wchar_t> c; // compile error: protected destructor
}
