```
    Diagnostics function to dump the DTM.

```
public String dumpNode(int nodeHandle)
```
    Diagnostics function to dump a single node. %REVIEW% KNOWN GLITCH: If you pass it a node index rather than a node handle, it works just fine... but the displayed identity number before the colon is different, which complicates comparing it with nodes printed the other way. We could always OR the DTM ID into the value, to suppress that distinction... %REVIEW% This might want to be moved up to DTMDefaultBase, or possibly DTM itself, since it's a useful diagnostic and uses only DTM's public APIs.

    Specified by:
    
    setFeature in interface DTM
    
    Parameters:
    featureId - A feature URL.
    state - true if this feature should be on, false otherwise.
  - hasChildNodes
```
public boolean hasChildNodes(int nodeHandle)
```
    Given a node handle, test if it has child nodes.
    %REVIEW% This is obviously useful at the DOM layer, where it would permit testing this without having to create a proxy node. It's less useful in the DTM API, where (dtm.getFirstChild(nodeHandle)!=DTM.NULL) is just as fast and almost as self-evident. But it's a convenience, and eases porting of DOM code to DTM.
    
    Specified by:
    
    hasChildNodes in interface DTM
    
    Parameters:
    nodeHandle - int Handle of the node.
    
    Returns:
    int true if the given node has child nodes.
  - makeNodeHandle
```
public final int makeNodeHandle(int nodeIdentity)
```
    Given a node identity, return a node handle. If extended addressing has been used (multiple DTM IDs), we need to map the high bits of the identity into the proper DTM ID. This has been made FINAL to facilitate inlining, since we do not expect any subclass of DTMDefaultBase to ever change the algorithm. (I don't really like doing so, and would love to have an excuse not to...) %REVIEW% Is it worth trying to specialcase small documents? %REVIEW% Should this be exposed at the package/public layers?
    
    Parameters:
    nodeIdentity - Internal offset to this node's records.
    
    Returns:
    NodeHandle (external representation of node)
  - makeNodeIdentity
```
public final int makeNodeIdentity(int nodeHandle)
```
    Given a node handle, return a node identity. If extended addressing has been used (multiple DTM IDs), we need to map the high bits of the identity into the proper DTM ID and thence find the proper offset to add to the low bits of the identity This has been made FINAL to facilitate inlining, since we do not expect any subclass of DTMDefaultBase to ever change the algorithm. (I don't really like doing so, and would love to have an excuse not to...) %OPT% Performance is critical for this operation. %REVIEW% Should this be exposed at the package/public layers?
    
    Parameters:
    nodeHandle - (external representation of node)
    
    Returns:
    nodeIdentity Internal offset to this node's records.
  - getFirstChild
```
public int getFirstChild(int nodeHandle)
```
    Given a node handle, get the handle of the node's first child. If not yet resolved, waits for more nodes to be added to the document and tries again.
    
    Specified by:
    
    getFirstChild in interface DTM
    
    Parameters:
    nodeHandle - int Handle of the node.
    
    Returns:

                             int namespaceNodeIndex)
```
    Build table of namespace declaration locations during DTM construction. Table is a Vector of SuballocatedIntVectors containing the namespace node HANDLES declared at that ID, plus an SuballocatedIntVector of the element node INDEXES at which these declarations appeared. NOTE: Since this occurs during model build, nodes will be encountered in doucment order and thus the table will be ordered by element, permitting binary-search as a possible retrieval optimization. %REVIEW% Directly managed arrays rather than vectors? %REVIEW% Handles or IDs? Given usage, I think handles.
  - findNamespaceContext
```
protected SuballocatedIntVector findNamespaceContext(int elementNodeIndex)
```
    Retrieve list of namespace declaration locations active at this node. List is an SuballocatedIntVector whose entries are the namespace node HANDLES declared at that ID. %REVIEW% Directly managed arrays rather than vectors? %REVIEW% Handles or IDs? Given usage, I think handles.

    Subroutine: Locate the specified node within m_namespaceDeclSetElements, or the last element which preceeds it in document order %REVIEW% Inlne this into findNamespaceContext? Create SortedSuballocatedIntVector type?
    
    Returns:
    If positive or zero, the index of the found item. If negative, index of the point at which it would have appeared, encoded as -1-index and hence reconvertable by subtracting it from -1. (Encoding because I don't want to recompare the strings but don't want to burn bytes on a datatype to hold a flagged value.)

public abstract 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
    
    Parameters:
    elementId - The unique id value for an element.
    
    Returns:
    The handle of the matching element.
  - getUnparsedEntityURI
```
public abstract 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.)

    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.
  - supportsPreStripping
```
public boolean supportsPreStripping()
```
    Return true if the xsl:strip-space or xsl:preserve-space was processed during construction of the DTM document.
    
    Specified by:
    
    supportsPreStripping in interface DTM
    
    Returns:
    true if this DTM supports prestripping.
  - isNodeAfter
```
public boolean isNodeAfter(int nodeHandle1,
                  int nodeHandle2)
```
    Figure out whether nodeHandle2 should be considered as being later in the document than nodeHandle1, in Document Order as defined by the XPath model. This may not agree with the ordering defined by other XML applications.
    There are some cases where ordering isn't defined, and neither are the results of this function -- though we'll generally return false.
    
    Specified by:
    
    isNodeAfter in interface DTM
    
    Parameters:
    nodeHandle1 - Node handle to perform position comparison on.
    nodeHandle2 - Second Node handle to perform position comparison on .
    
    Returns:
    true if node1 comes before node2, otherwise return false. You can think of this as (node1.documentOrderPosition <= node2.documentOrderPosition).
  - isCharacterElementContentWhitespace
```
public boolean isCharacterElementContentWhitespace(int nodeHandle)
```
    2. [element content whitespace] A boolean indicating whether the character is white space appearing within element content (see [XML], 2.10 "White Space Handling"). Note that validating XML processors are required by XML 1.0 to provide this information. If there is no declaration for the containing element, this property has no value for white space characters. If no declaration has been read, but the [all declarations processed] property of the document information item is false (so there may be an unread declaration), then the value of this property is unknown for white space characters. It is always false for characters that are not white space.
    
    Specified by:
    
    isCharacterElementContentWhitespace in interface DTM
    
    Parameters:
    nodeHandle - the node ID.
    
    Returns:
    true if the character data is whitespace; false otherwise.
  - isDocumentAllDeclarationsProcessed
```
public boolean isDocumentAllDeclarationsProcessed(int documentHandle)
```
    10. [all declarations processed] This property is not strictly speaking part of the infoset of the document. Rather it is an indication of whether the processor has read the complete DTD. Its value is a boolean. If it is false, then certain properties (indicated in their descriptions below) may be unknown. If it is true, those properties are never unknown.
    
    Specified by:
    
    isDocumentAllDeclarationsProcessed in interface DTM
    
    Parameters:
    documentHandle - A node handle that must identify a document.
    
    Returns:
    true if all declarations were processed; false otherwise.
  - isAttributeSpecified
```
public abstract 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
    
    Parameters:
    attributeHandle - The attribute handle in question.
    
    Returns:
    true if the attribute was specified; false if it was defaulted.

    Specified by:
    
    dispatchCharactersEvents in interface DTM
    
    Parameters:
    nodeHandle - The node ID.
    ch - A non-null reference to a ContentHandler.

    Throws:
    
    SAXException
  - dispatchToEvents
```
public abstract void dispatchToEvents(int nodeHandle,
                    ContentHandler ch)
                               throws SAXException
```

               boolean clone,
               boolean cloneDepth)
```
    Append a child to the end of the document. Please note that the node is always cloned if it is owned by another document.

    A dummy routine to satisify the abstract interface. If the DTM implememtation that extends the default base requires notification of registration, they can override this method.
    
    Specified by:
    
    documentRegistration in interface DTM
  - documentRelease
```
public void documentRelease()
```
    A dummy routine to satisify the abstract interface. If the DTM implememtation that extends the default base requires notification when the document is being released, they can override this method

    documentRelease in interface DTM
  - migrateTo
```
public void migrateTo(DTMManager mgr)
```
    Migrate a DTM built with an old DTMManager to a new DTMManager. After the migration, the new DTMManager will treat the DTM as one that is built by itself. This is used to support DTM sharing between multiple transformations.

    migrateTo in interface DTM
    
    Parameters:
    mgr - the DTMManager
  - getManager
```

    Query which DTMManager this DTM is currently being handled by. %REVEW% Should this become part of the base DTM API?
    
    Returns:
    a DTMManager, or null if this is a "stand-alone" DTM.
  - getDTMIDs
```
public SuballocatedIntVector getDTMIDs()
