public final class EdgeDrawing
extends Object
implements EdgeDrawingInterface

EdgeDrawing: implements all methods for drawing edges on canvas. Edges are drawn as black lines from the center of one vertex to the center of the other vertex. A square around the edge midpoint is the active portion of the edge, and will be drawn if GraphCanvas has "showEdgeCircles" set. Highlighted edges are red, and plain edges are black.

EdgeDrawing(Edge)
EdgeDrawing(EdgeList)

EdgeinRect(double, double, double, double): return true if active part of this edge is in rectangle
drawEdge(GraphCanvas): draw this edge on GraphCanvas
getShape(): getShape: does nothing for nondirected edges
midx(): return x-value of midpoint of this edge
midy(): return y-value of midpoint of this edge
ptInEdge(GraphCanvas, double, double): return true if pt(x,y) is in the active part of this edge
setShape(String): setShape: does nothing for nondirected edges
update(): recalculate drawing information for the edge
