public class DTMProxyMap

extends java.lang.Object

implements org.w3c.dom.NamedNodeMap

**For internal use only** DTMProxyMap is a quickie (as opposed to quick) implementation of the DOM's NamedNodeMap interface, intended to support DTMProxy's getAttributes() call.

***** Note: this does _not_ current attempt to cache any of the data; if you ask for attribute 27 and then 28, you'll have to rescan the first 27. It should probably at least keep track of the last one retrieved, and possibly buffer the whole array.

***** Also note that there's no fastpath for the by-name query; we search linearly until we find it or fail to find it. Again, that could be optimized at some cost in object creation/storage.

Method Summary

int	getLength() **For internal use only** Return the number of Attributes on this Element
org.w3c.dom.Node	getNamedItem(java.lang.String name) **For internal use only** Return the Attr node having a specific name
org.w3c.dom.Node	getNamedItemNS(java.lang.String namespaceURI, java.lang.String localName) **For internal use only** Retrieve a node specified by local name and namespace URI -- DOMLevel 2
org.w3c.dom.Node	item(int i) **For internal use only** Return the i'th Attr node bound to this element
org.w3c.dom.Node	removeNamedItem(java.lang.String name) **For internal use only** DOM API requires this, but DTM is a read-only model
org.w3c.dom.Node	removeNamedItemNS(java.lang.String namespaceURI, java.lang.String localName) **For internal use only** DOM 2 API requires this, but DTM is a read-only model
org.w3c.dom.Node	setNamedItem(org.w3c.dom.Node newNode) **For internal use only** DOM API requires this, but DTM is a read-only model
org.w3c.dom.Node	setNamedItemNS(org.w3c.dom.Node arg) **For internal use only** DOM 2 API requires this, but DTM is a read-only model
