public class BinaryArithMinusExpr
extends BinaryArithExpr

The BinaryArithMinusExpr class represents a minus expression. It extends binary arithmetic expressions so it contains a lefthand expression and a righthand expression. Since this class is similar to other subclasses most of the functionality can be implemented in the visitor method for the parent class.
