Examples of EdgeEnd

org.geotools.geometry.iso.topograph2D.EdgeEnd
Models the end of an edge incident on a node. EdgeEnds have a direction determined by the direction of the ray from the initial point to the next point. EdgeEnds are comparable under the ordering "a has a greater angle with the x-axis than b". This ordering is used to sort EdgeEnds around a node. @source $URL$
