AdaptiveResultTreeImpl
public class SimpleResultTreeImpl extends EmptySerializer implements DOM, DTM
This class represents a light-weight DOM model for simple result tree fragment(RTF). A simple RTF is an RTF that has only one Text node. The Text node can be produced by a combination of Text, xsl:value-of and xsl:number instructions. It can also be produced by a control structure (xsl:if or xsl:choose) whose body is pure Text.A SimpleResultTreeImpl has only two nodes, i.e. the ROOT node and its Text child. All DOM interfaces are overridden with this in mind. For example, the getStringValue() interface returns the value of the Text node. This class receives the character data from the characters() interface.
This class implements DOM and SerializationHandler. It also implements the DTM interface for support in MultiDOM. The nested iterators (SimpleIterator and SingletonIterator) are used to support the nodeset() extension function.

getUnparsedEntityURI
public java.lang.String getUnparsedEntityURI(java.lang.String name)
Description copied from interface:DTM
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. %REVIEW% 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.) %REVIEW% 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:

in interfaceDOM
- Specified by:

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.
%REVIEW% Make sure this does the right thing with attribute nodes!!!
%REVIEW% Consider renaming for clarity. Perhaps isDocumentOrder(a,b)?

in interfaceDTM
- Parameters:
firstNodeHandle
- DOM Node to perform position comparison on.secondNodeHandle

isCharacterElementContentWhitespace
public boolean isCharacterElementContentWhitespace(int nodeHandle)
Description copied from interface:DTM
2. [element content whitespace] A boolean indicating whether a text node represents 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... but that DOM Level 2 did not support it, since it depends on knowledge of the DTD which DOM2 could not guarantee would be available.If there is no declaration for the containing element, an XML processor must assume that the whitespace could be meaningful and return false. 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 indeterminate for white space characters and should probably be reported as false. It is always false for text nodes that contain anything other than (or in addition to) white space.
Note too that it always returns false for non-Text nodes.
%REVIEW% Joe wants to rename this isWhitespaceInElementContent() for clarity
- Specified by:
isCharacterElementContentWhitespace
in interfaceDTM
- Parameters:
nodeHandle
- the node ID.- Returns:
true
if the node definitely represents whitespace in element content;false
otherwise.

isDocumentAllDeclarationsProcessed
in interfaceDTM
- Parameters:
documentHandle

appendChild
public void appendChild(int newChild, boolean clone, boolean cloneDepth)
Description copied from interface:DTM
Append a child to "the end of the document". Please note that the node is always cloned in a base DTM, since our basic behavior is immutable so nodes can't be removed from their previous location.%REVIEW% DTM maintains an insertion cursor which performs a depth-first tree walk as nodes come in, and this operation is really equivalent to: insertionCursor.appendChild(document.importNode(newChild))) where the insert point is the last element that was appended (or the last one popped back to by an end-element operation).
