All Implemented Interfaces:

DTM
```
public class DOM2DTM
extends DTMDefaultBaseIterators
```
The DOM2DTM class serves up a DOM's contents via the DTM API. Note that it doesn't necessarily represent a full Document tree. You can wrap a DOM2DTM around a specific node and its subtree and the right things should happen. (I don't _think_ we currently support DocumentFrgment nodes as roots, though that might be worth considering.) Note too that we do not currently attempt to track document mutation. If you alter the DOM after wrapping DOM2DTM around it, all bets are off.

- Field Detail
  - m_nodes
```
protected Vector m_nodes
```
    The node objects. The instance part of the handle indexes directly into this vector. Each DTM node may actually be composed of several DOM nodes (for example, if logically-adjacent Text/CDATASection nodes in the DOM have been coalesced into a single DTM Text node); this table points only to the first in that sequence.
- Constructor Detail
  - DOM2DTM
```
public DOM2DTM(DTMManager mgr,
       DOMSource domSource,
       int dtmIdentity,
       DTMWSFilter whiteSpaceFilter,
       XMLStringFactory xstringfactory,
       boolean doIndexing)
```
    Construct a DOM2DTM object from a DOM node.
    
    Parameters:
    mgr - The DTMManager who owns this DTM.
    domSource - the DOM source that this DTM will wrap.
    dtmIdentity - The DTM identity ID for this DTM.
    whiteSpaceFilter - The white space filter for this DTM, which may be null.
    xstringfactory - XMLString factory for creating character content.
    doIndexing - true if the caller considers it worth it to use indexing schemes.
- Method Detail
  - addNode
```
protected int addNode(Node node,
          int parentIndex,
          int previousSibling,
          int forceNodeType)
```
    Construct the node map from the node.
    
    Parameters:
    node - The node that is to be added to the DTM.
    parentIndex - The current parent index.
    previousSibling - The previous sibling index.
    forceNodeType - If not DTM.NULL, overrides the DOM node type. Used to force nodes to Text rather than CDATASection when their coalesced value includes ordinary Text nodes (current DTM behavior).
    
    Returns:
    The index identity of the node that was added.
  - getNumberOfNodes
```
public int getNumberOfNodes()
```
    Get the number of nodes that have been added.
    
    Specified by:
    
    getNumberOfNodes in class DTMDefaultBase
    
    Returns:
    the number of nodes that have been mapped.
  - nextNode
```
protected boolean nextNode()
```
    This method iterates to the next node that will be added to the table. Each call to this method adds a new node to the table, unless the end is reached, in which case it returns null.
    
    Specified by:
    
    nextNode in class DTMDefaultBase
    
    Returns:
    The true if a next node is found or false if there are no more nodes.
  - getNode
```
public Node getNode(int nodeHandle)
```
    Return an DOM node for the given node.
    
    Specified by:
    
    getNode in interface DTM
    
    Overrides:
    
    getNode in class DTMDefaultBase
    
    Parameters:
    nodeHandle - The node ID.
    
    Returns:
    A node representation of the DTM node.
  - lookupNode
```
protected Node lookupNode(int nodeIdentity)
```
    Get a Node from an identity index. NEEDSDOC @param nodeIdentity NEEDSDOC ($objectName$) @return
  - getNextNodeIdentity
```
protected int getNextNodeIdentity(int identity)
```
    Get the next node identity value in the list, and call the iterator if it hasn't been added yet.
    
    Specified by:
    
    getNextNodeIdentity in class DTMDefaultBase
    
    Parameters:
    identity - The node identity (index).
    
    Returns:
    identity+1, or DTM.NULL.
  - getHandleOfNode
```
public int getHandleOfNode(Node node)
```
    Get the handle from a Node. This is a more robust version of getHandleFromNode, intended to be usable by the public.
    %OPT% This will be pretty slow.
    %REVIEW% This relies on being able to test node-identity via object-identity. DTM2DOM proxying is a great example of a case where that doesn't work. DOM Level 3 will provide the isSameNode() method to fix that, but until then this is going to be flaky.
    
    Parameters:
    node - A node, which may be null.
    
    Returns:
    The node handle or DTM.NULL.
  - getAttributeNode
```
public int getAttributeNode(int nodeHandle,
                   String namespaceURI,
                   String name)
```
    Retrieves an attribute node by by qualified name and namespace URI.
    
    Specified by:
    
    getAttributeNode in interface DTM
    
    Specified by:
    
    getAttributeNode in class DTMDefaultBase
    
    Parameters:
    nodeHandle - int Handle of the node upon which to look up this attribute..
    namespaceURI - The namespace URI of the attribute to retrieve, or null.
    name - The local name of the attribute to retrieve.
    
    Returns:
    The attribute node handle with the specified name ( nodeName) or DTM.NULL if there is no such attribute.
  - getStringValue
```
public XMLString getStringValue(int nodeHandle)
```
    Get the string-value of a node as a String object (see http://www.w3.org/TR/xpath#data-model for the definition of a node's string-value).
    
    Specified by:
    
    getStringValue in interface DTM
    
    Specified by:
    
    getStringValue in class DTMDefaultBase
    
    Parameters:
    nodeHandle - The node ID.
    
    Returns:
    A string object that represents the string-value of the given node.
  - isWhitespace
```
public boolean isWhitespace(int nodeHandle)
```
    Determine if the string-value of a node is whitespace
    
    Parameters:
    nodeHandle - The node Handle.
    
    Returns:
    Return true if the given node is whitespace.
  - getNodeData
```
protected static void getNodeData(Node node,
               FastStringBuffer buf)
```
    Retrieve the text content of a DOM subtree, appending it into a user-supplied FastStringBuffer object. Note that attributes are not considered part of the content of an element.
    There are open questions regarding whitespace stripping. Currently we make no special effort in that regard, since the standard DOM doesn't yet provide DTD-based information to distinguish whitespace-in-element-context from genuine #PCDATA. Note that we should probably also consider xml:space if/when we address this. DOM Level 3 may solve the problem for us.
    %REVIEW% Actually, since this method operates on the DOM side of the fence rather than the DTM side, it SHOULDN'T do any special handling. The DOM does what the DOM does; if you want DTM-level abstractions, use DTM-level methods.
    
    Parameters:
    node - Node whose subtree is to be walked, gathering the contents of all Text or CDATASection nodes.
    buf - FastStringBuffer into which the contents of the text nodes are to be concatenated.
  - getNodeName
```
public String getNodeName(int nodeHandle)
```
    Given a node handle, return its DOM-style node name. This will include names such as #text or #document.
    
    Specified by:
    
    getNodeName in interface DTM
    
    Specified by:
    
    getNodeName in class DTMDefaultBase
    
    Parameters:
    nodeHandle - the id of the node.
    
    Returns:
    String Name of this node, which may be an empty string. %REVIEW% Document when empty string is possible... %REVIEW-COMMENT% It should never be empty, should it?
  - getNodeNameX
```
public String getNodeNameX(int nodeHandle)
```
    Given a node handle, return the XPath node name. This should be the name as described by the XPath data model, NOT the DOM-style name.
    
    Specified by:
    
    getNodeNameX in interface DTM
    
    Overrides:
    
    getNodeNameX in class DTMDefaultBase
    
    Parameters:
    nodeHandle - the id of the node.
    
    Returns:
    String Name of this node, which may be an empty string.
  - getLocalName
```
public String getLocalName(int nodeHandle)
```
    Given a node handle, return its XPath-style localname. (As defined in Namespaces, this is the portion of the name after any colon character).
    
    Specified by:
    
    getLocalName in interface DTM
    
    Specified by:
    
    getLocalName in class DTMDefaultBase
    
    Parameters:
    nodeHandle - the id of the node.
    
    Returns:
    String Local name of this node.
  - getPrefix
```
public String getPrefix(int nodeHandle)
```
    Given a namespace handle, return the prefix that the namespace decl is mapping. Given a node handle, return the prefix used to map to the namespace.
    %REVIEW% Are you sure you want "" for no prefix?
    
    %REVIEW-COMMENT% I think so... not totally sure. -sb
    
    Specified by:
    
    getPrefix in interface DTM
    
    Specified by:
    
    getPrefix in class DTMDefaultBase
    
    Parameters:
    nodeHandle - the id of the node.
    
    Returns:
    String prefix of this node's name, or "" if no explicit namespace prefix was given.
  - getNamespaceURI
```
public String getNamespaceURI(int nodeHandle)
```
    Given a node handle, return its DOM-style namespace URI (As defined in Namespaces, this is the declared URI which this node's prefix -- or default in lieu thereof -- was mapped to.)
    %REVIEW% Null or ""? -sb

    String URI value of this node's namespace, or null if no namespace was resolved.
  - getNodeValue
```
public String getNodeValue(int nodeHandle)
```
    Given a node handle, return its node value. This is mostly as defined by the DOM, but may ignore some conveniences.
    
    Specified by:
    
    getNodeValue in interface DTM
    
    Specified by:
    
    getNodeValue in class DTMDefaultBase
    
    Parameters:
    nodeHandle - The node id.
    
    Returns:
    String Value of this node, or null if not meaningful for this node type.
  - getDocumentTypeDeclarationSystemIdentifier
```
public String getDocumentTypeDeclarationSystemIdentifier()
```
    A document type declaration information item has the following properties: 1. [system identifier] The system identifier of the external subset, if it exists. Otherwise this property has no value.
    
    Specified by:
    
    getDocumentTypeDeclarationSystemIdentifier in interface DTM
    
    Specified by:
    
    getDocumentTypeDeclarationSystemIdentifier in class DTMDefaultBase
    
    Returns:
    the system identifier String object, or null if there is none.
  - getDocumentTypeDeclarationPublicIdentifier
```
public String getDocumentTypeDeclarationPublicIdentifier()
```
    Return the public identifier of the external subset, normalized as described in 4.2.2 External Entities [XML]. If there is no external subset or if it has no public identifier, this property has no value.
    
    Specified by:
    
    getDocumentTypeDeclarationPublicIdentifier in interface DTM
    
    Specified by:
    
    getDocumentTypeDeclarationPublicIdentifier in class DTMDefaultBase
    
    Returns:
    the public identifier String object, or null if there is none.
  - getElementById
```
public int getElementById(String elementId)
```
    Returns the Element whose ID is given by elementId. If no such element exists, returns DTM.NULL. Behavior is not defined if more than one element has this ID. Attributes (including those with the name "ID") are not of type ID unless so defined by DTD/Schema information available to the DTM implementation. Implementations that do not know whether attributes are of type ID or not are expected to return DTM.NULL.
    %REVIEW% Presumably IDs are still scoped to a single document, and this operation searches only within a single document, right? Wouldn't want collisions between DTMs in the same process.
    
    Specified by:
    
    getElementById in interface DTM
    
    Specified by:
    
    getElementById in class DTMDefaultBase
    
    Parameters:
    elementId - The unique id value for an element.
    
    Returns:
    The handle of the matching element.
  - getUnparsedEntityURI
```
public String getUnparsedEntityURI(String name)
```
    The getUnparsedEntityURI function returns the URI of the unparsed entity with the specified name in the same document as the context node (see [3.3 Unparsed Entities]). It returns the empty string if there is no such entity.
    XML processors may choose to use the System Identifier (if one is provided) to resolve the entity, rather than the URI in the Public Identifier. The details are dependent on the processor, and we would have to support some form of plug-in resolver to handle this properly. Currently, we simply return the System Identifier if present, and hope that it a usable URI or that our caller can map it to one. TODO: Resolve Public Identifiers... or consider changing function name.
    If we find a relative URI reference, XML expects it to be resolved in terms of the base URI of the document. The DOM doesn't do that for us, and it isn't entirely clear whether that should be done here; currently that's pushed up to a higher level of our application. (Note that DOM Level 1 didn't store the document's base URI.) TODO: Consider resolving Relative URIs.
    (The DOM's statement that "An XML processor may choose to completely expand entities before the structure model is passed to the DOM" refers only to parsed entities, not unparsed, and hence doesn't affect this function.)
    
    Specified by:
    
    getUnparsedEntityURI in interface DTM
    
    Specified by:
    
    getUnparsedEntityURI in class DTMDefaultBase
    
    Parameters:
    name - A string containing the Entity Name of the unparsed entity.
    
    Returns:
    String containing the URI of the Unparsed Entity, or an empty string if no such entity exists.
  - isAttributeSpecified
```
public boolean isAttributeSpecified(int attributeHandle)
```
    5. [specified] A flag indicating whether this attribute was actually specified in the start-tag of its element, or was defaulted from the DTD.
    
    Specified by:
    
    isAttributeSpecified in interface DTM
    
    Specified by:
    
    isAttributeSpecified in class DTMDefaultBase
    
    Parameters:
    attributeHandle - the attribute handle
    
    Returns:
    true if the attribute was specified; false if it was defaulted.
  - setIncrementalSAXSource
```
public void setIncrementalSAXSource(IncrementalSAXSource source)
```
    Bind an IncrementalSAXSource to this DTM. NOT RELEVANT for DOM2DTM, since we're wrapped around an existing DOM.
    
    Parameters:
    source - The IncrementalSAXSource that we want to recieve events from on demand.
  - getContentHandler
```
public ContentHandler getContentHandler()
```
    getContentHandler returns "our SAX builder" -- the thing that someone else should send SAX events to in order to extend this DTM model.
    
    Returns:
    null if this model doesn't respond to SAX events, "this" if the DTM object has a built-in SAX ContentHandler, the IncrmentalSAXSource if we're bound to one and should receive the SAX stream via it for incremental build purposes...
  - getLexicalHandler
```
public LexicalHandler getLexicalHandler()
```
    Return this DTM's lexical handler. %REVIEW% Should this return null if constrution already done/begun?
    
    Returns:
    null if this model doesn't respond to lexical SAX events, "this" if the DTM object has a built-in SAX ContentHandler, the IncrementalSAXSource if we're bound to one and should receive the SAX stream via it for incremental build purposes...
  - getEntityResolver
```
public EntityResolver getEntityResolver()
```
    Return this DTM's EntityResolver.
    
    Returns:
    null if this model doesn't respond to SAX entity ref events.
  - getDTDHandler
```
public DTDHandler getDTDHandler()
```
    Return this DTM's DTDHandler.
    
    Returns:
    null if this model doesn't respond to SAX dtd events.
  - getErrorHandler
```
public ErrorHandler getErrorHandler()
```
    Return this DTM's ErrorHandler.
    
    Returns:
    null if this model doesn't respond to SAX error events.
  - getDeclHandler
```
public DeclHandler getDeclHandler()
```
    Return this DTM's DeclHandler.
    
    Returns:
    null if this model doesn't respond to SAX Decl events.
  - needsTwoThreads
```
public boolean needsTwoThreads()
```
    Returns:
    true iff we're building this model incrementally (eg we're partnered with a IncrementalSAXSource) and thus require that the transformation and the parse run simultaneously. Guidance to the DTMManager.
  - dispatchCharactersEvents
```
public void dispatchCharactersEvents(int nodeHandle,
                            ContentHandler ch,

                                throws SAXException
```
    Retrieve the text content of a DOM subtree, appending it into a user-supplied FastStringBuffer object. Note that attributes are not considered part of the content of an element.
    There are open questions regarding whitespace stripping. Currently we make no special effort in that regard, since the standard DOM doesn't yet provide DTD-based information to distinguish whitespace-in-element-context from genuine #PCDATA. Note that we should probably also consider xml:space if/when we address this. DOM Level 3 may solve the problem for us.
    %REVIEW% Note that as a DOM-level operation, it can be argued that this routine _shouldn't_ perform any processing beyond what the DOM already does, and that whitespace stripping and so on belong at the DTM level. If you want a stripped DOM view, wrap DTM2DOM around DOM2DTM.
    
    Parameters:
    node - Node whose subtree is to be walked, gathering the contents of all Text or CDATASection nodes.
    
    Throws:
    
    SAXException
  - dispatchToEvents
```
public void dispatchToEvents(int nodeHandle,
                    ContentHandler ch)
                      throws SAXException
```
    Directly create SAX parser events from a subtree.
    
    Specified by:
    
    dispatchToEvents in interface DTM
    
    Specified by:
    
    dispatchToEvents in class DTMDefaultBase
    
    Parameters:
    nodeHandle - The node ID.
    ch - A non-null reference to a ContentHandler.
    
    Throws:
    
    SAXException
  - setProperty
```
public void setProperty(String property,
               Object value)
```
    For the moment all the run time properties are ignored by this class.
    
    Parameters:
    property - a String value
    value - an Object value
  - getSourceLocatorFor
```
public SourceLocator getSourceLocatorFor(int node)
```
    No source information is available for DOM2DTM, so return null here.
    
    Parameters:
    node - an int value
    
    Returns:
    null
