## org.apache.batik.dom.traversal
Class DOMNodeIterator

    java.lang.Object
      org.apache.batik.dom.traversal.DOMNodeIterator

All Implemented Interfaces:
  org.w3c.dom.traversal.NodeIterator

public class DOMNodeIterator
extends java.lang.Object
implements org.w3c.dom.traversal.NodeIterator

This class implements the `NodeIterator` interface.

Field Summary
`protected static short` | `BACKWARD` The backward state.
`protected AbstractDocument` | `document` The document which created the iterator.
`protected boolean` | `expandEntityReferences` Whether the children of entity reference nodes are visible to the iterator.
`protected org.w3c.dom.traversal.NodeFilter` | `filter` The NodeFilter used to screen nodes.
`protected static short` | `FORWARD` The forward state.
`protected static short` | `INITIAL` The initial state.
`protected static short` | `INVALID` The invalid state.
`protected org.w3c.dom.Node` | `referenceNode` The reference node.
`protected org.w3c.dom.Node` | `root` The root node.
`protected short` | `state` The iterator state.
`protected int` | `whatToShow` Which node types are presented via the iterator.

Constructor Summary
`DOMNodeIterator(AbstractDocument doc, org.w3c.dom.Node n, int what, org.w3c.dom.traversal.NodeFilter nf, boolean exp)` Creates a new NodeIterator object.

Method Summary
`void` | `detach()` DOM: Implements `NodeIterator.detach()`.
`boolean` | `getExpandEntityReferences()` DOM: Implements `NodeIterator.getExpandEntityReferences()`.
`org.w3c.dom.traversal.NodeFilter` | `getFilter()` DOM: Implements `NodeIterator.getFilter()`.

`int` | `getWhatToShow()` DOM: Implements `NodeIterator.getWhatToShow()`.
`org.w3c.dom.Node` | `nextNode()` DOM: Implements `NodeIterator.nextNode()`.
`void` | `nodeToBeRemoved(org.w3c.dom.Node removedNode)` Called by the DOM when a node will be removed from the current document.
`org.w3c.dom.Node` | `previousNode()` DOM: Implements `NodeIterator.previousNode()`.
`protected void` | `unfilteredNextNode()` Sets the reference node to the next node, unfiltered.
`protected void` | `unfilteredPreviousNode()` Sets the reference node to the previous node, unfiltered.
