Interface DirectedEdge

All Superinterfaces:

DirectedGraphable, Edge, Graphable

All Known Implementing Classes:

BasicDirectedEdge, OptDirectedEdge

public interface DirectedEdge

extends Edge, DirectedGraphable

Represents an edge in a directed graph. A directed edge catagorizes its nodes as originating (in node), and terminating (out node). The edge is an out edge of its in node and an in edge to its out node.
