Class kraft.monitor.display.Node

java.lang.Object
   |
   +----kraft.monitor.display.Node

public class Node
extends Object
implements DisplayEvent

The graphical representation of a Monitorable agent in the visualisation tool.

Will draw the agent as a red circle with the agent's name nearby it -- the orientation of the label with respect to the circle can be changed.

This object will also store a set of status strings which are relevant at particular steps in the visualisation -- calling setCurrentIndex will determine which status string is relevant at that point.

If there is a relevant status string, the node's colour will be set to green.
Mouse clicks on the object (via calls to

 MousePressedHasEffect and 
 MouseReleasedHasEffect

) will cause the currently relevant status string to be shown when the object is repainted.

 public void unpaint(Graphics g)

paint

 public void paint(Graphics g)

Display this Node on the graphics context. Set colour and display status string depending on the current index number we are at (ie. the visualisation step)

See Also:: setCurrentIndex

getContextString
