NodeVisitor Class Template Reference
[NodeVisitor]

Visitors are used to extend the Node classes without changing their implementation ('visitor pattern') NodeVisitor is the base class of all visitors. Visitors use an iterator to traverse the tree. So the result depends on the given iteration algorithm. If set to non-recursive they only visit one node. The default value is true, so the visitor works recursively. More...
