Looking for a better C++ class factory

Question

I have an application that has several objects (about 50 so far, but growing). There is only one instance of each of these objects in the app and these instances get shared

Answer 1

Use a template class as the broker.
Make the instance a static member of the function. It will be created on first use and automagically-destroyed when the program exits.

template 
class BrokeredObject
{
    public:
        static Type& getInstance()
        {
            static Type theInstance;

            return theInstance;
        }
}; 

class TestObject
{
    public:
       TestObject()
       {}
};


int main()
{
    TestObject& obj =BrokeredObject::getInstance();
}
