java.lang.Object org.apache.commons.configuration.HierarchicalConfiguration.NodeVisitor
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.
