### getUnparsedEntityURI

    public java.lang.String getUnparsedEntityURI(java.lang.String parm1)

  Description copied from class: `DTMDefaultBase`
  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:
    `parm1` -
  Returns:
    String containing the URI of the Unparsed Entity, or an empty string if no such entity exists.

### getDTDHandler

    public DTDHandler getDTDHandler()

  Description copied from interface: `DTM`
  Return this DTM's DTDHandler, if it has one.

  Returns:
    null if this model doesn't respond to SAX dtd events.

### getPrefix

    public java.lang.String getPrefix(int parm1)

  Description copied from class: `DTMDefaultBase`
  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

    `getPrefix` in interface `DTM`

### getEntityResolver

    public EntityResolver getEntityResolver()

  Description copied from class: `DTMDefaultBase`
  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.

    null if this model doesn't respond to lexical SAX events.

### needsTwoThreads

    public boolean needsTwoThreads()

  Returns:

    public boolean hasChildNodes(int parm1)

  Description copied from class: `DTMDefaultBase`
  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`
  Overrides:

  Specified by:
    `getNodeType` in interface `DTM`

  Description copied from class: `DTMDefaultBase`
  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`
  Overrides:
    `isCharacterElementContentWhitespace` in class `DTMDefaultBase`
  Parameters:
    `parm1` -

### getElementById

    public int getElementById(java.lang.String parm1)

  Description copied from class: `DTMDefaultBase`
  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:
