net.mumie.mathletfactory.math.algebra.op.RationalOpHolder

public class RationalOpHolder
extends java.lang.Object

This class acts as a container for a node rooting a rational expression in zero, one or multiple variables. It bundles the functionality used for rational expressions (getting the Domain, etc.).
