Constructor Detail

OrthogonalEdgeRouter

public OrthogonalEdgeRouter()

Create a new edge router for a fixed scene of rectangles.

Method Detail

getBlockLocation

protected java.awt.Point getBlockLocation(java.util.UUID id)

Specified by:

getBlockLocation in class AbstractEdgeRouter

setup

public void setup(java.util.Map<java.util.UUID,java.awt.Rectangle> rectangles)

Resets this edge router's set of rectangles, which are the obstacles for otho routing.

route

protected java.util.List<java.awt.Point> route(java.awt.Point start,
                                               java.awt.Point end,
                                               java.awt.Point trueStart,
                                               java.awt.Point trueEnd)

Description copied from class: AbstractEdgeRouter

Find the route from start to end. The "true" start and end points are provided for reference but should not be part of the route, and may be null depending on the type of route being created. (These points will be the "anchor" points whereas the start and end points are the lead points)

Specified by:

route in class AbstractEdgeRouter

getCost

public java.lang.Double getCost()

getGraph

public SimpleGraph<java.awt.Point,OrthogonalEdgeRouter.Line> getGraph()

Return the most recent Orthogonal Visibility Graph

paintDebug

public void paintDebug(java.awt.Graphics2D g)

Description copied from interface: EdgeRouter

Optional. An opportunity to paint debug info. Turned on with -DEdgeRouter.DebugPaint=true
