Class EdgeShape<V,E>

java.lang.Object

edu.uci.ics.jung.visualization.decorators.EdgeShape<V,E>

Type Parameters:

V - the vertex type

E - the edge type

public class EdgeShape<V,E>
extends Object

An interface for decorators that return a Shape for a specified edge. All edge shapes must be defined so that their endpoints are at (0,0) and (1,0). They will be scaled, rotated and translated into position by the PluggableRenderer.

Nested Classes

Modifier and Type	Class	Description
class	EdgeShape.BentLine	An edge shape that renders as a bent-line between the vertex endpoints.
class	EdgeShape.Box	An edge shape that renders as a diamond with its nadir at the center of the vertex.
class	EdgeShape.CubicCurve	An edge shape that renders as a CubicCurve between vertex endpoints.
class	EdgeShape.Line	An edge shape that renders as a straight line between the vertex endpoints.
class	EdgeShape.Loop	An edge shape that renders as a loop with its nadir at the center of the vertex.
class	EdgeShape.Orthogonal	An edge shape that renders as a bent-line between the vertex endpoints.
class	EdgeShape.QuadCurve	An edge shape that renders as a QuadCurve between vertex endpoints.
class	EdgeShape.SimpleLoop	An edge shape that renders as a loop with its nadir at the center of the vertex.
class	EdgeShape.Wedge	An edge shape that renders as an isosceles triangle whose apex is at the destination vertex for directed edges, and as a "bowtie" shape for undirected edges.
