Eclipse Draw2d
3.3

org.eclipse.draw2d
Class RelativeBendpoint

java.lang.Object
  extended by
org.eclipse.draw2d.RelativeBendpoint
All Implemented Interfaces:
Bendpoint

public class RelativeBendpoint
extends java.lang.Object
implements Bendpoint

RelativeBendpoint is a Bendpoint that calculates its location based on its distance from the start and end points of the Connection, as well as its weight. See setWeight(float) for a description of what behavior different weights will provide.


Constructor Summary
RelativeBendpoint ()
          Constructs a new RelativeBendpoint.
RelativeBendpoint ( Connection conn)
          Constructs a new RelativeBendpoint and associates it with the given Connection.
 
Method Summary
protected   Connection getConnection ()
          Returns the Connection this Bendpoint is associated with.
  Point getLocation ()
          Calculates and returns this Bendpoint's new location.
 void setConnection ( Connection conn)
          Sets the Connection this bendpoint should be associated with.
 void setRelativeDimensions ( Dimension dim1, Dimension dim2)
          Sets the Dimensions representing the X and Y distances this Bendpoint is from the start and end points of the Connection.
 void setWeight (float w)
          Sets the weight this Bendpoint should use to calculate its location.

Constructor Detail

RelativeBendpoint

public RelativeBendpoint()
Constructs a new RelativeBendpoint.

Since:
2.0

RelativeBendpoint

public RelativeBendpoint(
Connection conn)
Constructs a new RelativeBendpoint and associates it with the given Connection.

Parameters:
conn - The Connection this Bendpoint is associated with
Since:
2.0
Method Detail

getConnection

protected 
Connection getConnection()
Returns the Connection this Bendpoint is associated with.

Returns:
The Connection this Bendpoint is associated with
Since:
2.0

getLocation

public 
Point getLocation()
Calculates and returns this Bendpoint's new location.

Specified by:
getLocation in interface Bendpoint
Returns:
This Bendpoint's new location
Since:
2.0

setConnection

public void setConnection(
Connection conn)
Sets the Connection this bendpoint should be associated with.

Parameters:
conn - The Connection this bendpoint should be associated with
Since:
2.0

setRelativeDimensions

public void setRelativeDimensions(
Dimension dim1,
                                  
Dimension dim2)
Sets the Dimensions representing the X and Y distances this Bendpoint is from the start and end points of the Connection. These Dimensions are generally set once and are used in calculating the Bendpoint's location.

Parameters:
dim1 - The X and Y distances this Bendpoint is from the start of the Connection
dim2 - The X and Y distances this Bendpoint is from the end of the Connection
Since:
2.0

setWeight

public void setWeight(float w)
Sets the weight this Bendpoint should use to calculate its location. The weight should be between 0.0 and 1.0. A weight of 0.0 will cause the Bendpoint to follow the start point, while a weight of 1.0 will cause the Bendpoint to follow the end point. A weight of 0.5 (the default) will cause the Bendpoint to maintain its original aspect ratio between the start and end points.

Parameters:
w - The weight
Since:
2.0
