Class StickyRectangleConnector

java.lang.Object
  org.jhotdraw.draw.AbstractConnector
      org.jhotdraw.draw.ChopRectangleConnector
          org.jhotdraw.draw.StickyRectangleConnector

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, Connector, DOMStorable

public class StickyRectangleConnector
extends ChopRectangleConnector

A StickyRectangleConnector locates connection Points by choping the connection between the centers of the two figures at the display box.

The location of the connection Point2D.Double is computed once, when the user connects the figure. Moving the figure around will not change the location.

StickyRectangleConnector

public StickyRectangleConnector()

Creates a new instance. Only used for storable.

Method Detail

draw

public void draw(java.awt.Graphics2D g)

Description copied from interface: Connector

Draws the connector.

Specified by:

draw in interface Connector

Overrides:

draw in class AbstractConnector

setAngle

public void setAngle(float angle)

getAngle

public double getAngle()

updateAnchor

public void updateAnchor(java.awt.geom.Point2D.Double p)

Description copied from interface: Connector

Updates the anchor of the connector. This method is called when the user manually changes the end point of the ConnectionFigure. The Connector uses this as a hint for choosing a new anchor position.

Specified by:

updateAnchor in interface Connector

Overrides:

updateAnchor in class AbstractConnector

getAnchor

public java.awt.geom.Point2D.Double getAnchor()

Description copied from interface: Connector

Gets the anchor of the connector. This is a point at the center or at the bounds of the figure, where the start or the end point will most likely be attached. The purpose of this method is to give the user a hint, where the connector will most likely be attached to the owner of the connector.

Specified by:

getAnchor in interface Connector

Overrides:

getAnchor in class AbstractConnector

chop

protected java.awt.geom.Point2D.Double chop(Figure target,
                                            java.awt.geom.Point2D.Double from)

Overrides:

chop in class ChopRectangleConnector

getParameters

public java.lang.String getParameters()

read

public void read(DOMInput in)
          throws java.io.IOException

Specified by:

read in interface DOMStorable

Overrides:

read in class AbstractConnector

Throws:

java.io.IOException

write

public void write(DOMOutput out)
           throws java.io.IOException

Specified by:

write in interface DOMStorable

Overrides:

write in class AbstractConnector

Throws:

java.io.IOException
