Class kraft.monitor.display.Link 

java.lang.Object
   |
   +----kraft.monitor.display.Link
public class Link
extends Object
implements DisplayEvent
Defines the graphic representation of a Message passed between two Monitorable objects.

This is a 'link' between two Node objects. Represented as an arrow containing the command name of the message. A mouse click on the object ( via calls to mousePressedHasEffect and mouseReleasedHasEffect ) will cause this object to display more information about itself graphically when it is repainted.
