All Implemented Interfaces:
AnchorListener, Connection, IFigure

public class PolylineConnection
extends Polyline
implements Connection, AnchorListener

An implementation of Connection based on Polyline. PolylineConnection adds the following additional features:

  • A ConnectionRouter may be provided which will be used to determine the connections points.
  • Children may be added. The bounds calculation is extended such that the bounds is the smallest Rectangle which is large enough to display the Polyline and all of its children figures.
  • A DelegatingLayout is set as the default layout. A delegating layout allows children to position themselves via Locators.

Constructor Detail

PolylineConnection

public PolylineConnection()
Method Detail

addNotify

public void addNotify()
Hooks the source and target anchors.

Specified by:
addNotify in interface IFigure
Overrides:
addNotify in class Figure
See Also:
Figure.addNotify()

addRoutingListener

public void addRoutingListener(
RoutingListener listener)
Appends the given routing listener to the list of listeners.

Parameters:
listener - the routing listener
Since:
3.2

anchorMoved

public void anchorMoved(
ConnectionAnchor anchor)
Called by the anchors of this connection when they have moved, revalidating this polyline connection.

Specified by:
anchorMoved in interface AnchorListener
Parameters:
anchor - the anchor that moved

getBounds

public 
Rectangle getBounds()
Returns the bounds which holds all the points in this polyline connection. Returns any previously existing bounds, else calculates by unioning all the children's dimensions.

Specified by:
getBounds in interface IFigure
Overrides:
getBounds in class Polyline
Returns:
the bounds
See Also:
IFigure.getBounds()

getConnectionRouter

public 
ConnectionRouter getConnectionRouter()
Returns the ConnectionRouter used to layout this connection. Will not return null.

Specified by:
getConnectionRouter in interface Connection
Returns:
this connection's router

getRoutingConstraint

public java.lang.Object getRoutingConstraint()
Returns this connection's routing constraint from its connection router. May return null.

Specified by:
getRoutingConstraint in interface Connection
Returns:
the connection's routing constraint

getSourceAnchor

public 
ConnectionAnchor getSourceAnchor()
Description copied from interface: Connection
Returns the ConnectionAnchor at the source end of this Connection.

Specified by:

protected 
RotatableDecoration getTargetDecoration()
Returns:
the target decoration (may be null)
Since:

layout

public void layout()
Layouts this polyline. If the start and end anchors are present, the connection router is used to route this, after which it is laid out. It also fires a moved method.

revalidate in interface IFigure
Overrides:
revalidate in class Figure
See Also:
IFigure.revalidate()

cr - the connection router

setRoutingConstraint

public void setRoutingConstraint(java.lang.Object cons)
Sets the routing constraint for this connection.

anchor - the new source anchor

setSourceDecoration

public void setSourceDecoration(
RotatableDecoration dec)
Sets the decoration to be used at the start of the Connection.

Parameters:
dec - the new source decoration
Since:
2.0

setTargetAnchor

public void setTargetAnchor(
ConnectionAnchor anchor)
Sets the anchor to be used at the end of the polyline connection. Removes this listener from the old anchor and adds it to the new anchor.

Specified by:
setTargetAnchor in interface Connection
