Interface (entête) :
<code cpp>
#include <memory>

class Fridge
{
public:
   Fridge();
   ~Fridge();
   void coolDown();
private:
   class FridgeImpl;
   std::unique_ptr<FridgeImpl> impl_;
};
</code>

Implémentation (source) :

<code cpp>
#include "Fridge.h"
#include <iostream>

class Fridge::FridgeImpl
{
public:
   void coolDown()
   {
      std::cout << "coucou\n";
   }
private:
   int engine_;
};

Fridge::Fridge() : impl_(new FridgeImpl()) {}
Fridge::~Fridge() = default;
void Fridge::coolDown() { impl_->coolDown(); }
</code>
