public class InfiniteElement
InfiniteElement is a special Element used to represent the largest and smallest possible elements. The only two instances of InfiniteElement are two static objects, INFINITY and MINUS_INFINITY. Each of these objects are exposed as InfiniteElement.INFINITY and InfiniteElement.MINUS_INFINITY. The compareTo function handles comparisons between the InfiniteElements and other Elements. Other elements should defer to the InfiniteElement compareTo when comparing to an InfiniteElement.
