It declares m_children to be a linked list of pointers to a general tree containing objects of type dataType.


class MyClass { ... };
GeneralTree<MyClass> myTree;


In the above code, I have declared myTree to be an object of type GeneralTree that contains objects of type MyClass. So, the m_children member will be a linked list of pointers to general tree contain objects of type MyClass.
