RatRectangle2D

public RatRectangle2D(Point2D p1,
                      Point2D p2)
               throws InvalidPointException

Parameters:

p1 - a corner of the rectangle; must be an integer or rational point

p2 - the corner of the rectangle diagonally opposite to p1; must be an integer or rational point

Throws:

InvalidPointException - if p1 and p2 are not integer or rational points, or if p1 and p2 are not diagonally opposite
