Adds the directed edge e to this edge-weighted digraph.

Returns the directed edges incident from vertex v.

Returns all directed edges in this edge-weighted digraph. To iterate over the edges in this edge-weighted digraph, use foreach notation: foreach (DirectedEdge e in G.Edges()).

Returns the number of directed edges incident to vertex v. This is known as the Indegree of vertex v.

Demo test the EdgeWeightedDigraph data type.

Returns the number of directed edges incident from vertex v. This is known as the Outdegree of vertex v.

Returns a string representation of this edge-weighted digraph.
