o Transition 
 public Transition(State ifrom,
                   String ilabel,
                   State ito)

Methods

o move 
 public void move(int x,
                  int y)
o slope 
 public double slope()
Returns the slope of the line between the from and to states.

o paintLabel 
 public void paintLabel(Graphics g,
                        Transition selectedTransition,
                        Point pl)
Paints the label of a transition.

o paintLine 
 public void paintLine(Graphics g,
                       Transition selectedTransition)
Paints the line of a transition.

o computeArrow 
 public void computeArrow(Point pl,
                          int xPoints[],
                          int yPoints[])
Computes the points of the little triangle which shows the direction of the transition.

Parameters:
pl - the upper left corner of the transition's label.
xpoints - the x coordinates of the points representing the arrow.
ypoints - the y coordinates of the points representing the arrow.
o processKey 
 public boolean processKey(int key,
                           KeyEvent e)
processes a KeyEvent that occured in this transition for the Desktop.

o tokenizeLabel 
 public void tokenizeLabel()
Tokenizes the given label. The result is stored in the sublabel array.

o tokenizeOrList 
 public Vector tokenizeOrList()
returns a Vector of Strings corresponding to the list of ORed transitions represented by this Transition works only for FSA's

o setLabel 
 public void setLabel(Vector aVector)
