java.lang.Object
  AutomaticRouter
      com.ibm.etools.systems.application.visual.editor.routers.internal.RectilinearFanRouter

public class RectilinearFanRouter
extends AutomaticRouter

The router that detects and avoids the rectilinear connection line overlapping. The connection will fan out in a similar way as oblique fan router does but with rectilinear lines.

RectilinearFanRouter

public RectilinearFanRouter()

Method Detail

route

public void route(Connection conn)

Routes the given connection. Calls the 'next' router first (if one exists) and if no bendpoints were added by the next router, collisions are dealt with by calling handleCollision(PointList, int).

Parameters:

conn - The connection to route

shouldCheckOverlapping

protected boolean shouldCheckOverlapping(Connection conn)

Check if the given connection is overlapped with other connections.

getConnections

protected RectilinearFanRouter.MultiValueMap getConnections()

getSeparation

public int getSeparation()

Returns the separation in pixels between fanned connections.

Returns:

the separation

Since:

2.0

setSeparation

public void setSeparation(int separation)

Set the separation in pixels between fanned connections.

handleCollision

protected void handleCollision(PointList points,
                               int index)

handleCollisionWith2

protected void handleCollisionWith2(PointList points,
                                    int index)

Handle collision if there are only two points in connection, ie, either vertical or horizontal lines.

Parameters:

points -

index -

handleCollisionWith3

protected void handleCollisionWith3(PointList points,
                                    int index)

Handle collision with connection which has 3 points ( start point, vertex bendpoint, end point)

Parameters:

points -

index -
