All Implemented Interfaces:

EvaluationVisitor, Visitor<Value,java.lang.Object>

Direct Known Subclasses:

TracingEvaluationVisitor

public abstract class EvaluationVisitorDecorator
extends AbstractExtendingVisitor<Value,java.lang.Object>
implements EvaluationVisitor

A visitor that decorates another EvaluationVisitor, to intercept invocations of the visitXxx(...) methods. By default, every visitation is simply delegated to the decorated visitor. Subclasses may extend these delegations with any additional behaviour that is required, even replacing calls to the delegate where necessary.

This class works together with the AbstractEvaluationVisitor to ensure that recursive visitXxx() calls are correctly intercepted by me (and not just implemented within the decorated visitor). Moreover, this works with decorators nested to any depth.
