o distance(BoundaryCircle, BoundaryCircle)
Compute the distance between the centers of two BoundaryCircles.
o makeNeg(BoundaryCircle)
Makes a negative BoundaryCircle corresponding to the input of a positive one.
o paint(Graphics, BoundaryPanel, Choice)
Paint this BoundaryCircle if it is not too huge, paying attention to the currently selected display type.
o toString()
Make a string out of this's index.

ndx - the index of this BoundaryCircle
domaintype - the selected index of outputpanel's Choice fordordirichlet
o BoundaryCircle 
 public BoundaryCircle(int ndx)
Constructor for BoundaryCircles of parabolic traces.

Parameters:
ndx - the index of this BoundaryCircle
o BoundaryCircle 
 public BoundaryCircle()
Constructor of a trivial BoundaryCircle.

Methods

o paint 
 public void paint(Graphics g,
                   BoundaryPanel boundarypanel,
                   Choice diskorcircle)
Paint this BoundaryCircle if it is not too huge, paying attention to the currently selected display type.

Parameters:
g - the graphics object upon which to paint
boundarypanel - the ambient BoundaryPanel
diskorcircle - a reference to outputpanel's choice on the selected display type
o distance 
 public static double distance(BoundaryCircle a,
                               BoundaryCircle b)
Compute the distance between the centers of two BoundaryCircles.

Parameters:
a - one BoundaryCircle
b - and another
Returns:
the distance between their centers
o copyCircle 
 public BoundaryCircle copyCircle()
Copies this BoundaryCircle, by making a trivial BoundaryCircle and then copying into it this's center, radius and index.

Returns:
the new copy of this BounaryCircle
o makeNeg 
 public static BoundaryCircle makeNeg(BoundaryCircle pos)
Makes a negative BoundaryCircle corresponding to the input of a positive one.

Parameters:
pos - the positive BoundaryCircle to be copied and negated
Returns:
s the new negative BoundaryCircle
o toString 
 public String toString()
Make a string out of this's index. Only called implicitly when making a label for fundamental domain of impossible combinatorial type, by Vector.toString on DomainCombinatorics's Vector boundary.

Returns:
the string form of this's index
Overrides:
toString in class Object
