Detailed Description

This is the base class for all visitors who wish to preform some operation from the state of the expression tree. Using double dispatching, subclasses of Constraint expression call back to the InterpreterVisitor subclass from the accept method.

Traversal of the expression tree uses the "Visitor" pattern. To "visit" a node, a client invokes the "accept" method on a subclass of ConstraintExpression, which, in turn, invokes the appropriate method on the visitor passed to it, based on its own type. So, the Constraint_Visitor has a method to deal with each possible type of node in an expression tree; one for each operator in the grammar.
