public class UnaryIncrExpr
extends UnaryExpr

The UnaryIncrExpr class represents increment shortcut 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.
