```
public class DTMDocumentImpl
extends java.lang.Object
implements DTM, org.xml.sax.ContentHandler, org.xml.sax.ext.LexicalHandler
```
This is the implementation of the DTM document interface. It receives requests from an XML content handler similar to that of an XML DOM or SAX parser to store information from the xml document in an array based dtm table structure. This informtion is used later for document navigation, query, and SAX event dispatch functions. The DTM can also be used directly as a document composition model for an application. The requests received are:
- initiating DTM to set the doc handle
- resetting DTM for data structure reuse
- hinting the end of document to adjust the end of data structure pointers
- createnodes (element, comment, text, attribute, ....)
- hinting the end of an element to patch parent and siblings
- setting application provided symbol name stringpool data structures
State: In progress!!
%REVIEW% I _think_ the SAX convention is that "no namespace" is expressed as "" rather than as null (which is the DOM's convention). What should DTM expect? What should it do with the other?
Origin: the implemention is a composite logic based on the DTM of XalanJ1 and DocImpl, DocumentImpl, ElementImpl, TextImpl, etc. of XalanJ2

public DTMDocumentImpl(DTMManager mgr,
                       int documentNumber,
                       DTMWSFilter whiteSpaceFilter,
                       XMLStringFactory xstringfactory)
```
    Construct a DTM.
    
    Parameters:
    
    documentNumber - the ID number assigned to this document. It will be shifted up into the high bits and returned as part of all node ID numbers, so those IDs indicate which document they came from as well as a location within the document. It is the DTMManager's responsibility to assign a unique number to each document.
- Method Detail
  - setIncrementalSAXSource
```
public void setIncrementalSAXSource(IncrementalSAXSource source)
```
    Bind a IncrementalSAXSource to this DTM. If we discover we need nodes that have not yet been built, we will ask this object to send us more events, and it will manage interactions with its data sources. Note that we do not actually build the IncrementalSAXSource, since we don't know what source it's reading from, what thread that source will run in, or when it will run.
    
    Parameters:
    
    source - The IncrementalSAXSource that we want to recieve events from on demand.

```
public int getDocumentRoot(int nodeHandle)
```
    Given a node handle, find the owning document node. This has the DTM semantics; a Document node is its own owner.
    %REVIEW% Since this is DOM-specific, it may belong at the DOM binding layer. Included here as a convenience function and to aid porting of DOM code to DTM.
    
    Specified by:
    
    getDocumentRoot in interface DTM
    
    Parameters:
    
    nodeHandle - the id of the node.

    Specified by:
    
    getStringValue in interface DTM
    
    Parameters:
    
    nodeHandle - The node ID.
    
    Returns:
    
    A string object that represents the string-value of the given node.
  - getStringValueChunkCount
```
public int getStringValueChunkCount(int nodeHandle)
```
    Get number of character array chunks in the string-value of a node. (see http://www.w3.org/TR/xpath#data-model for the definition of a node's string-value). Note that a single text node may have multiple text chunks. EXPLANATION: This method is an artifact of the fact that the underlying m_chars object may not store characters in a single contiguous array -- for example,the current FastStringBuffer may split a single node's text across multiple allocation units. This call tells us how many separate accesses will be required to retrieve the entire content. PLEASE NOTE that this may not be the same as the number of SAX characters() events that caused the text node to be built in the first place, since m_chars buffering may be on different boundaries than the parser's buffers.
    
    Specified by:
    
    getStringValueChunkCount in interface DTM
    
    Parameters:
    
    nodeHandle - The node ID.
    
    Returns:
    
    number of character array chunks in the string-value of a node.
  - getStringValueChunk
```
public char[] getStringValueChunk(int nodeHandle,

                                  int[] startAndLen)
```
    Get a character array chunk in the string-value of a node. (see http://www.w3.org/TR/xpath#data-model for the definition of a node's string-value). Note that a single text node may have multiple text chunks. EXPLANATION: This method is an artifact of the fact that the underlying m_chars object may not store characters in a single contiguous array -- for example,the current FastStringBuffer may split a single node's text across multiple allocation units. This call retrieves a single contiguous portion of the text -- as much as m-chars was able to store in a single allocation unit. PLEASE NOTE that this may not be the same granularityas the SAX characters() events that caused the text node to be built in the first place, since m_chars buffering may be on different boundaries than the parser's buffers.
    
    Specified by:
    
    getStringValueChunk in interface DTM
    
    Parameters:
    
    nodeHandle - The node ID.

    startAndLen - An array of 2 where the start position and length of the chunk will be returned.
    
    Returns:
    
    The character array reference where the chunk occurs.

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 java.lang.String getUnparsedEntityURI(java.lang.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
    
    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.
    %REVEIW% Presumes a 1:1 mapping from DTM to Document, since we aren't saying which Document to query...?
    
    Specified by:
    
    supportsPreStripping in interface DTM
  - 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 true. TODO: Make sure this does the right thing with attribute nodes!!!
    
    Specified by:
    
    isNodeAfter in interface DTM
    
    Parameters:
    
    nodeHandle1 - DOM Node to perform position comparison on.
    
    nodeHandle2 - DOM Node to perform position comparison on .
    
    Returns:
    
    false if node2 comes before node1, otherwise return true. 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 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
    
    Returns:
    
    true if the attribute was specified; false if it was defaulted.
