DescendantIterator (saxon JavaDoc)

java.lang.Object
- net.sf.saxon.tree.tiny.DescendantIterator

All Implemented Interfaces:

Closeable, AutoCloseable, SequenceIterator<NodeInfo>, AxisIterator, UnfailingIterator<NodeInfo>
```
final class DescendantIterator
extends Object
implements AxisIterator
```
This class supports both the descendant:: and descendant-or-self:: axes, which are identical except for the route to the first candidate node. It enumerates descendants of the specified node. This version includes all text nodes in the result (assuming they are matched), but does not handle grafted external nodes The calling code must ensure that the start node is not an attribute or namespace node.
