public static class HierarchicalConfiguration.NodeVisitor extends Object
Definition of a visitor class for traversing a node and all of its children.
This class defines the interface of a visitor for
Node objects and provides a default implementation. The
method visit() of Node implements a generic
iteration algorithm based on the Visitor pattern. By providing
different implementations of visitors it is possible to collect different
data during the iteration process.
