| Subject: on empty edge |
|
|
what's so special about an empty edge such that class EmptyEdge has *eight* extra member functions which are neither in the Edge interface and nor the WebEdge class (in fact, WebEdge straightly implements only those in the Edge interface) ?
any feedback to help me understand the essential is greatly appreciated!
