ChordDisplayPanel
public ChordDisplayPanel(InfrastructureModel m)
- Creates a chord display panel that
renders data from the specified infrastructure
data model.

nodeAdded in interface InfrastructureModel.EventListener
nodeRemoved
public void nodeRemoved(com.ubermq.chord.ChordNode x)
- Specified by:
nodeRemoved in interface InfrastructureModel.EventListener

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.

getIdentifierOrigin
private java.awt.Point getIdentifierOrigin()
getIdentifierRadius
private int getIdentifierRadius()
translateIdentifier
private double translateIdentifier(com.ubermq.chord.ChordIdentifier i)
- Calculates the angle representing where the identifier lies on
the identifier circle, in radians. This method relies on
the
hashCode method to provide a reasonable
mapping of identifier space onto the 2^32 values provided by
the primitive int Java type.
calculateNodeCoordinates
private java.awt.Point calculateNodeCoordinates(com.ubermq.chord.ChordNode n,
int r)
- Gets the rectangular location for a node on a circle of radius r,
centered at the origin.
main
public static void main(java.lang.String[] s)
- Constructs the message viewer application window.
