Detailed Description

Define Visitable classes as:.

 class Element : public Visitable<>
 {
  public:
   VISITABLE_ACCEPT()
 };
 

 class SubElement : public Element
 {
  public:
   VISITABLE_ACCEPT()
 };
 

Define a Visitor as:

 class SomeVisitor : public IVisitor,
                 public Visitor<Element>,
                 public Visitor<SubElement>
 {
  public:
   void accept(Element&) { ... }
   void accept(SubElement&) { ... }
 };
 

Optionally the visitor accept method may want to return values:

 class Element : public Visitable<Element*>
 

and the visitor defines:

 Element* SomeVisitor::accept(Element&) { ... }
