Detailed Description

template<class SingletonClass>
class coil::Singleton< SingletonClass >

Singleton template class.

This class template makes any classed into Singleton classes. Usage is as follows.

class A { // }; typedef coil::Singleton<A> A_;

In the any places, A& a(A_:instance()); // a has singular instance of A

Since the constructor of A is still public, however, user can create other instance of A as follows.

A* a = new A();

If you want to prohibit user from creating new instance, please inherit Singleton class (CRTP) and declare it as a friend class in the target class.

class A : public coil::Singleton<A> { public: private: A(){}

friend class coil::Singelton<A>; };

A* a = new A(); // compile error A& a(A::instance()); // This is the only method to get unique instance
