public abstract class BinaryLogicExpr
extends BinaryExpr

The abstract BinaryLogicExpr class represents boolean logic expressions. It can be either AND ('&&') or OR ('||'). It extends BinaryExpr and contains a lefthand expression and a righthand expression. Most of the functionality can be implemented within the visitor method for BinaryExpr, however, some functionality may need to be implemented in the visitor method for each subclass.
