Class imageGenerator  

java.lang.Object
  java.awt.Component
      java.awt.Container
          javax.swing.JComponent
              exptree.utilities.imageGenerator

All Implemented Interfaces:

java.lang.Cloneable, java.awt.image.ImageObserver, java.awt.MenuContainer, java.lang.Runnable, java.io.Serializable

---

public class imageGenerator

extends javax.swing.JComponent

implements java.lang.Runnable, java.lang.Cloneable

Generates an image based on expressionTrees. Currently, this supports images in the RGB and HSB colorspaces, and therefore takes 3 expressionTrees. The image generation takes place in a thread, and does not begin until the startIt() method is called.

Version:

1.1 08/19/2000

run in interface java.lang.Runnable

---

stop

paint

public void paint(java.awt.Graphics g)

Description copied from class: javax.swing.JComponent

Paint the component. This is a delicate process, and should only be called from the repaint thread, under control of the javax.swing.RepaintManager. Client code should usually call Component.repaint()>Component.repaint() 55 to trigger painting.

The body of the paint call involves calling JComponent.paintComponent(java.awt.Graphics)>JComponent.paintComponent(java.awt.Graphics) 55 , JComponent.paintBorder(java.awt.Graphics)>JComponent.paintBorder(java.awt.Graphics) 55 , and JComponent.paintChildren(java.awt.Graphics)>JComponent.paintChildren(java.awt.Graphics) 55 in order. If you want to customize painting behavior, you should override one of these methods rather than paint.

For more details on the painting sequence, see this article.

---

update

public void update(java.awt.Graphics g)

Description copied from class: javax.swing.JComponent

Call JComponent.paint(java.awt.Graphics)>JComponent.paint(java.awt.Graphics) 55 .

---

getImage

public java.awt.image.BufferedImage getImage()

---

addChangeListener

public void addChangeListener(javax.swing.event.ChangeListener l)

Adds a ChangeListener to the image.

---

removeChangeListener

public void removeChangeListener(javax.swing.event.ChangeListener l)

Removes a ChangeListener from the button.

---

fireStateChanged

protected void fireStateChanged()

Notify all listeners that have registered interest for notification on this event type. The event instance is lazily created using the parameters passed into the fire method.

---

addFinishedListener

public void addFinishedListener(javax.swing.event.ChangeListener l)

Adds a ChangeListener to the image.

---

removeFinishedListener

public void removeFinishedListener(javax.swing.event.ChangeListener l)

Removes a ChangeListener from the button.

---

fireFinished

protected void fireFinished()

Notify all listeners that have registered interest for notification on this event type. The event instance is lazily created using the parameters passed into the fire method.

---

clone

protected java.lang.Object clone()

Description copied from class: java.lang.Object

This method may be called to create a new copy of the Object. The typical behavior is as follows:

• o == o.clone() is false
• o.getClass() == o.clone().getClass() is true
• o.equals(o) is true

However, these are not strict requirements, and may be violated if necessary. Of the three requirements, the last is the most commonly violated, particularly if the subclass does not override Object.equals(Object)>Object.equals(Object) 55 .

If the Object you call clone() on does not implement java.lang.Cloneable (which is a placeholder interface), then a CloneNotSupportedException is thrown. Notice that Object does not implement Cloneable; this method exists as a convenience for subclasses that do.

Object's implementation of clone allocates space for the new Object using the correct class, without calling any constructors, and then fills in all of the new field values with the old field values. Thus, it is a shallow copy. However, subclasses are permitted to make a deep copy.

All array types implement Cloneable, and override this method as follows (it should never fail):

 public Object clone()
 {
   try
     {
       super.clone();
     }
   catch (CloneNotSupportedException e)
     {
       throw new InternalError(e.getMessage());
     }
 }

getClone

public imageGenerator getClone()

---

initImage

private java.awt.image.BufferedImage initImage(int width,
                                               int height)

---

isFinished

public boolean isFinished()

---

getImageGeneratorParams

public imageGeneratorParams getImageGeneratorParams()

---

toString

public java.lang.String toString()

Description copied from class: java.awt.Component

Returns a string representation of this component. This is implemented as getClass().getName() + '[' + paramString() + ']'.

---

map

static double map(double a)

---

getSize

public java.awt.Dimension getSize(java.awt.Dimension rv)

Description copied from class: javax.swing.JComponent

Get the component's size. The passed-in java.awt.Dimension value will be used as the return value, if possible.
