How to declare a variable with nested templates?

For a personal project, I want to create a generic graph. I have created 3 main classes:

-the graph class: template <typename NODE,typename ARROW> class ClassicGraphe;
-the node class: template <typename ARROW> class ClassicNode;
-the arc class: template <typename NODE> class ClassicArrow;

The node class and the arc class are nested together. For the declaration of the variable, I suppose it will not be something like this:

 ClassicNode<ClassicArrow<ClassicNode<...>>> myNode;

So how can I declare a ClassicNode variable?
