Hi Sam,
You have complete control over what you do before and after traversal,
there really isn't any need to have a finalize method as it would only
restrict what users can do over what they can already do.
If you wanted an finialize method in your visitor then just write a
method like:
MyVisitor : public NodeVisitor {
void apply(...) // all my apply overrides your need...
void process(Node* node)
{
// do what you want to initialize the visitor prior
// to traversing the scene graph
node->accept(node);
// do what you want after traversal
}
};
MyVisitor myvistor;
myvisitor->process(node);
The visitor implementation is deliberately designed to allow you to be
flexible, it's up to you how you want to go about implementing the
details for the purpose of your application.
Robert.
