I feel that I'm missing something, but what if you store the type of the 
vertex in the base class: ?
class BaseVertex { int m_type; public: BaseVertex() : m_type(0) {} };
struct EntryVertex : public BaseVertex {  EtntryVertex() : m_type(1) {} };
Then, you can determine the type of the vertex at run time )
