This class describes the base interface of undirected graph types. All graph concepts have to conform to this class. It extends the interface of BaseDigraphComponent with an Edge type and functions to get the end nodes of edges, to convert from arcs to edges and to get both direction of edges.

This function returns a directed arc from its direction and the represented edge.
This function returns a directed arc from its source node and the represented edge.
