An abstract trait representing a directed edge in a graph.
This trait extends the Edge trait, providing a specific implementation for the edgeType method, which always returns Directed. The directed edge represents a one-way connection between two vertices.
Type parameters
E
the type of the attribute associated with the edge.
Retrieves the blackVertex of this Connexion. If this is a DirectedEdge, this vertex represents the end. If this is an UndirectedEdge, see the note above for white.

Retrieves the whiteVertex of this Connexion. If this is a DirectedEdge, this vertex represents the start. If this is an UndirectedEdge, white to black represents the nominal direction. Individual adjacencies can be based on a flipped version of an UndirectedEdge.
