Class RelativeBendpoint

java.lang.Object
  
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
