Destruction-Managed Singleton
A Compound Pattern for Reliable Deallocation of Singletons
Evgeniy Gabrilovich
Listing 4. Sample main program (main.cxx).
#include "dmanager.h"
#include "resource.h"
class DestroyObjects {
public:
~DestroyObjects()
{ DestructionManager::instance.destroy_objects(); }
};
void main(void) {
DestroyObjects() destroyer;
// ...
Resource::instance().process();
// The destructor of 'destroyer' is invoked automatically on exit
// from 'main()', commencing the controlled destruction of singletons.
}
