Examples of DirectedEdge

@version 1.7

com.vividsolutions.jts.planargraph.DirectedEdge

Represents a directed edge in a {@link PlanarGraph}. A DirectedEdge may or may not have a reference to a parent {@link Edge} (some applications ofplanar graphs may not require explicit Edge objects to be created). Usually a client using a PlanarGraph will subclass DirectedEdge to add its own application-specific data and methods. @version 1.7

org.geotools.graph.structure.DirectedEdge

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. @see DirectedGraph @author Justin Deoliveira, Refractions Research Inc, jdeolive@refractions.net @source $URL$
