public class UnaryNotExpr
extends UnaryExpr

The UnaryNotExpr class represents logical not (complement) expressions. It extends unary expressions so it contains an expression. Since this class is similar to other subclasses most of the functionality can be implemented in the visitor method for the parent class.
