Class Traverser

java.lang.Object

iaik.xml.filter.impl.dsig.Traverser

All Implemented Interfaces:

Iterator

public class Traverser
extends Object
implements Iterator

A traverser that returns all nodes of a Document from a given root Node.

The returned Nodes are returned in document order (according to XML Path Language (XPath) Version 1.0, Section 5 ) with the following restriction: the order of the namespace and attribute child nodes of an element is not necessarily in document order but fixed for a given Document.

This Traverser emulates an Iterator over the result of evaluating the XPath expression (//. | //@* | //namespace::*) with the XPath evaluation context setting the initial node equal to the given root node, and setting the context position and size to 1.
