org.eclipse.draw2d
Class ConnectionLayer

java.lang.Object
  extended by

org.eclipse.draw2d.Figure
      extended by

org.eclipse.draw2d.Layer
          extended by

org.eclipse.draw2d.FreeformLayer
              extended by
org.eclipse.draw2d.ConnectionLayer
All Implemented Interfaces:
FreeformFigure, IFigure

public class ConnectionLayer
extends FreeformLayer

Layer designed specifically to handle the presence of connections. This is done due to the necessity of having a router for the connections added.

Field Detail

connectionRouter

protected 
ConnectionRouter connectionRouter
The ConnectionRouter used to route all connections on this layer.

Constructor Detail

ConnectionLayer

public ConnectionLayer()
Method Detail

add

public void add(
IFigure figure,
                java.lang.Object constraint,
                int index)
Adds the given figure with the given contraint at the given index. If the figure is a Connection, its ConnectionRouter is set.

Specified by:
add in interface IFigure
Overrides:
add in class FreeformLayer
Parameters:
figure - Figure being added
constraint - Constraint of the figure being added
index - Index where the figure is to be added
Since:
2.0
See Also:
IFigure.add(IFigure, Object, int)

getConnectionRouter

public 
ConnectionRouter getConnectionRouter()
Returns the ConnectionRouter being used by this layer.

Returns:
ConnectionRouter being used by this layer
Since:
2.0

paint

public void paint(
Graphics graphics)
Description copied from interface: IFigure
Paints this IFigure and its children.

Specified by:
paint in interface IFigure
Overrides:
paint in class Figure
Parameters:
graphics - The Graphics object used for painting
See Also:
IFigure.paint(Graphics)

remove

public void remove(
IFigure figure)
Removes the figure from this Layer. If the figure is a Connection, that Connection's ConnectionRouter is set to null.

Specified by:
remove in interface IFigure
Overrides:
remove in class FreeformLayer
Parameters:
figure - The figure to remove
See Also:
IFigure.remove(IFigure)

setConnectionRouter

public void setConnectionRouter(
ConnectionRouter router)
Sets the ConnectionRouter for this layer. This router is set as the ConnectionRouter for all the child connections of this Layer.

Parameters:
router - The ConnectionRouter to set for this Layer
Since:
2.0

setAntialias

public void setAntialias(int antialias)
Sets whether antialiasing should be enabled for the connection layer. If this value is set to something other than SWT#DEFAULT, Graphics.setAntialias(int) will be called with the given value when painting this layer.

Parameters:
antialias - the antialias setting
Since:
3.1
