public class DTM
extends org.apache.xerces.framework.XMLParser
implements java.lang.Runnable, org.apache.xerces.framework.XMLDocumentHandler, org.apache.xerces.framework.XMLDocumentHandler.DTDHandler

**For internal use only** `DTM` is an XML document model expressed as a table rather than an object tree. It attempts to be very compact, and to support very specifically limited multitasking: users can start reading the document while it's still being generated. (A work in progress...)

(***** The SAX handler calls, and the string-based XMLDocumentHandler methods, are known to be bad; they're included as hooks for the future.)

DTM does _not_ directly support the W3C's Document Object Model. However, it attempts to come close enough that a subset of DOM behavior can be implemented as proxy objects referencing the DTM.

    public DTM()

  **For internal use only** Construct a DTM. This is the only constructor currently working.
  Parameters:
    `parser` - HookedXMLParser Input event-stream source.

### DTM

    public DTM(ProblemListener listener)

  **For internal use only** Construct a DTM. This is the only constructor currently working.
  Parameters:
    `parser` - HookedXMLParser Input event-stream source.

Method Detail

### getStringPool

    public org.apache.xerces.utils.StringPool getStringPool()

  **For internal use only** Make the string public.

### setInputSource

    public void setInputSource(org.xml.sax.InputSource inputSource)

### setProblemListener

    public void setProblemListener(ProblemListener listener)

  **For internal use only** Set the current problem listener.

### reset

    public void reset()
               throws java.lang.Exception

  **For internal use only** Override reset so it doesn't release the string pool. DTM parsers are not reuseable (because the DTM is the same object as the parser).
  Overrides:
    reset in class org.apache.xerces.framework.XMLParser

### run

    public void run()

  **For internal use only** Run the parse thread.
  Specified by:
    run in interface java.lang.Runnable

### getNode

    public final DTMProxy getNode(int pos)

  **For internal use only** Return a Node object that represents the index.

### startDocument

    public final void startDocument()

  **For internal use only** XMLDocumentHandler API: Start-of-document recieved. Much like the SAX startDocument() and setDocumentLocator() calls, but also has the side effect of switching DTM into its XML4J-aware mode.
  Specified by:
    startDocument in interface org.apache.xerces.framework.XMLDocumentHandler

### startDocument

    public final void startDocument(int versionIndex,
                                    int encodingIndex,
                                    int standAloneIndex)

  **For internal use only** XMLDocumentHandler API: Start-of-document recieved. Much like the SAX startDocument() and setDocumentLocator() calls, but also has the side effect of switching DTM into its XML4J-aware mode.

### endDocument

    public final void endDocument()
                           throws org.xml.sax.SAXException

  **For internal use only** SAX API: End of Document reached. Finalize the DTM: close out the sibling chain, mark the document as no-more-nodes-expected, and wake up anyone who is waiting.
  Specified by:
    endDocument in interface org.apache.xerces.framework.XMLDocumentHandler
  Throws:
    org.xml.sax.SAXException - Not used.

### startElement

    public final void startElement(org.apache.xerces.utils.QName qname,
                                   org.apache.xerces.framework.XMLAttrList xmlAttrList,
                                   int attrListIndex)

  **For internal use only** XMLDocumentHandler API: Process element start-tag and its attributes. This includes pushing a new namespace context (with any namespaces declared on this element), creating the Element node, making it the new parent, and creating child Attribute nodes as needed. Namespace declarations _do_ appear as attributes. Attributes are expressed as the leading children of the Element, and are separated out later, which is different from DOM's behavior.

  The mapping from namespace prefixes to namespace URIs is also performed at this time.

  Specified by:
    startElement in interface org.apache.xerces.framework.XMLDocumentHandler
  Parameters:
    `elementNameIndex` - int Index of element's qualified name in symbol table.
    `attrListIndex` - int Starting index of this element's attributes in the parser's attribute table, or -1 to indicate no attributes.

### endElement

    public final void endElement(org.apache.xerces.utils.QName name)

  **For internal use only** XMLDocumentHandler API: End-tag reached. Pop the parentage context, along with any namespaces this element defined. Make sure that the sibling chain has been properly terminated.
  Specified by:
    endElement in interface org.apache.xerces.framework.XMLDocumentHandler
  Parameters:
    `name` - int Index of element name in XML4J's symbol table

                          throws org.xml.sax.SAXException

  **For internal use only** SAX API: Accept a chunk of characters for normalization into a Text node. Note that since SAX may reuse its input buffers, we may need to either extract the string now or cache a copy of the buffer. It is unclear which approach is preferable
  Specified by:
    characters in interface org.apache.xerces.framework.XMLDocumentHandler
  Parameters:
    `ch` - char[] Input buffer in which string can be found.
    `start` - int Offset to start of string, 0-based.

                  throws java.lang.Exception

  **For internal use only** callback for the start of the DTD This function will be called when a <!DOCTYPE...> declaration is encountered.
  Specified by:
    startDTD in interface org.apache.xerces.framework.XMLDocumentHandler.DTDHandler
  Parameters:
    `rootElementType` - element handle for the root element of the document
    `publicId` - string pool index of the DTD's public ID
    `systemId` - string pool index of the DTD's system ID
  Throws:
    java.lang.Exception -
  Overrides:
    startDTD in class org.apache.xerces.framework.XMLParser

### characters

    public final void characters(char[] ch,
                                 int start,
                                 int length,
                                 boolean cdataSection)
                          throws org.xml.sax.SAXException

  **For internal use only** XMLDocumentHandler API: Accept a chunk of characters for normalization into a Text node. This is an "enhanced SAX" flavor of the call, adding the flag for CDATA sections, and is not currently used.

                                   throws org.xml.sax.SAXException

  **For internal use only** XMLDocumentHandler API: Accept a chunk of characters for normalization into an ignorable-whitespace Text node. This is the "late binding" version of the call, which we currently rely upon.
  Parameters:
    `dataIndex` - int Index of this string in XML4J's symbol tables
    `cdataSection` - boolean True iff text was enclosed in
  Throws:
    org.xml.sax.SAXException - Required by API, not thrown as far as I know.

### general_characters

    public final void general_characters(int index)

  **For internal use only** Text-accumulator operation for the integer-index version of characters(). Obviously far simpler, since we are assured that (unlike the parse buffers) the XML4J symbol table will persist.
  Parameters:
    `index` - int Index of this string in XML4J's symbol tables.

    Note: Even though we are using XML4J's internal events rather than SAX, we must be prepared to normalize successive blocks of characters():

    - when text runs over the end of a parse buffer (may not arise in this parser),
    - when text and CDATA sections are intermixed (with intervening start/end CDATA events),
    - and when text and entity references are intermixed (with intervening start/end Entity Reference events).
    The simplest way to handle this is to record the data, but defer creating the Text node until we get an event indicating that no further text will arrive. This logic was present in early versions of DTM, but was lost during an overagressive optimization; we're restoring it now.

    Note: Yes, the charChunks array grows monotonically during parsing, and does not shrink back down when the chunks are concatenated later in processing. Tough. I'm assuming that this is cheaper than allocating a separate array for every multichunk string, despite the block-copying that occurs when the array is grown.

    KNOWN LIMITATION: DOESN'T PRESERVE CDATA FLAG. Since XSLT doesn't care about that flag, this is not a problem for our target application. It may be an issue if you try to reuse DTM elsewhere.
