NAME¶

std::collate::~collate - std::collate::~collate

Synopsis¶

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

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

Example¶

// Run this code

#include <iostream>
#include <locale>

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

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