Nice way to implement thread-safe singleton pattern with enhanced security
#include <ctime>
#include <chrono>
class Singleton
{
private:
Singleton() { }
void operator delete(void*) {}; // such that its not deleted accidentally
public:
Singleton(Singleton&) = delete; // Copy prohibited
void operator=(const Singleton&) = delete; // Assignment prohibited
Singleton& operator=(Singleton&&) = delete; // Move assignment
static Singleton* getInstance();
// This is a sample method
std::chrono::system_clock::time_point getTime() const {
auto now = std::chrono::system_clock::now();
return now;
};
};
Singleton* Singleton::getInstance() {
static Singleton* pInstance_;
return pInstance_;
}
