public class AdaptiveResultTreeImpl
extends SimpleResultTreeImpl

AdaptiveResultTreeImpl is a adaptive DOM model for result tree fragments (RTF). It is used in the case where the RTF is likely to be pure text yet it can still be a DOM tree. It is designed for RTFs which have <xsl:call-template> or <xsl:apply-templates> in the contents. Example:

        <xsl:variable name = "x">
          <xsl:call-template name = "test">
             <xsl:with-param name="a" select="."/>
          </xsl:call-template>
        </xsl:variable>

In this example the result produced by is likely to be a single Text node. But it can also be a DOM tree. This kind of RTF cannot be modelled by SimpleResultTreeImpl.

AdaptiveResultTreeImpl can be considered as a smart switcher between SimpleResultTreeImpl and SAXImpl. It treats the RTF as simple Text and uses the SimpleResultTreeImpl model at the beginning. However, if it receives a call which indicates that this is a DOM tree (e.g. startElement), it will automatically transform itself into a wrapper around a SAXImpl. In this way we can have a light-weight model when the result only contains simple text, while at the same time it still works when the RTF is a DOM tree.

All methods in this class are overridden to delegate the action to the wrapped SAXImpl object if it is non-null, or delegate the action to the SimpleResultTreeImpl if there is no wrapped SAXImpl.

%REVISIT% Can we combine this class with SimpleResultTreeImpl? I think it is possible, but it will make SimpleResultTreeImpl more expensive. I will use two separate classes at this time.

### 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.)

  Description copied from class: `SimpleResultTreeImpl`
  We only need to override the endDocument, characters, and setEscaping interfaces. A simple RTF does not have element nodes. We do not need to touch startElement and endElement.

  Description copied from interface: `ContentHandler`
  Receive notification of the end of a document.

  The SAX parser will invoke this method only once, and it will be the last method invoked during the parse. The parser shall not invoke this method until it has either abandoned parsing (because of an unrecoverable error) or reached the end of input.

### characters

    public void characters(java.lang.String str)
                    throws SAXException

  Description copied from interface: `ExtendedContentHandler`
  This method is used to notify of a character event, but passing the data as a character String rather than the standard character array.

  Specified by:
    `characters` in interface `ExtendedContentHandler`
  Overrides:
    `characters` in class `SimpleResultTreeImpl`
  Throws:
    `SAXException`

### characters

    public void characters(char[] ch,
                           int offset,
                           int length)
                    throws SAXException

  Description copied from interface: `ContentHandler`
  Receive notification of character data.

  The Parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity so that the Locator provides useful information.

  The application must not attempt to read from the array outside of the specified range.

  Individual characters may consist of more than one Java `char` value. There are two important cases where this happens, because characters can't be represented in just sixteen bits. In one case, characters are represented in a Surrogate Pair, using two special Unicode values. Such characters are in the so-called "Astral Planes", with a code point above U+FFFF. A second case involves composite characters, such as a base character combining with one or more accent characters.

  Your code should not assume that algorithms using `char`-at-a-time idioms will be working in character units; in some cases they will split characters. This is relevant wherever XML permits arbitrary characters, such as attribute values, processing instruction data, and comments as well as in data reported from this method. It's also generally relevant whenever Java code manipulates internationalized text; the issue isn't unique to XML.

  Note that some parsers will report whitespace in element content using the `ignorableWhitespace` method rather than this one (validating parsers must do so).

                      throws SAXException

  Description copied from interface: `ExtendedContentHandler`
  This method is used to notify that an element is starting. This method is just like the standard SAX method

                             Attributes attributes)
                      throws SAXException

  Description copied from interface: `ContentHandler`
  Receive notification of the beginning of an element.

  The Parser will invoke this method at the beginning of every element in the XML document; there will be a corresponding `endElement` event for every startElement event (even when the element is empty). All of the element's content will be reported, in order, before the corresponding endElement event.

  This event allows up to three name components for each element:

  1. the Namespace URI;
  2. the local name; and
  3. the qualified (prefixed) name.

  Any or all of these may be provided, depending on the values of the http://xml.org/sax/features/namespaces and the http://xml.org/sax/features/namespace-prefixes properties:

  - the Namespace URI and local name are required when the namespaces property is true (the default), and are optional when the namespaces property is false (if one is specified, both must be);
  - the qualified name is required when the namespace-prefixes property is true, and is optional when the namespace-prefixes property is false (the default).

  Note that the attribute list provided will contain only attributes with explicit values (specified or defaulted): #IMPLIED attributes will be omitted. The attribute list will contain attributes used for Namespace declarations (xmlns* attributes) only if the `http://xml.org/sax/features/namespace-prefixes` property is true (it is false by default, and support for a true value is optional).

  Like `characters()`, attribute values may have characters that need more than one `char` value.

  This method is used to notify that an element has ended. Unlike the standard SAX method

       endElement(namespaceURI,localName,qName)

  Description copied from interface: `ExtendedContentHandler`
  This method is used to notify that a prefix mapping is to start, but after an element is started. The SAX method call

       startPrefixMapping(prefix,uri)

  is used just before an element starts and applies to the element to come, not to the current element. This method applies to the current element. For example one could make the calls in this order:

       startElement("prfx8:elem9")
       namespaceAfterStartElement("http://namespace8","prfx8")

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.

    `getElementById` in interface `DTM`
  Overrides:
    `getElementById` in class `SimpleResultTreeImpl`

### supportsPreStripping

### isNodeAfter

    public boolean isNodeAfter(int firstNodeHandle,
                               int secondNodeHandle)

  Description copied from interface: `DTM`
  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)?

  Specified by:
    `isNodeAfter` in interface `DTM`
  Overrides:
    `isNodeAfter` in class `SimpleResultTreeImpl`

### 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

    `isCharacterElementContentWhitespace` in interface `DTM`
  Overrides:
    `isCharacterElementContentWhitespace` in class `SimpleResultTreeImpl`

### isDocumentAllDeclarationsProcessed

    public boolean isDocumentAllDeclarationsProcessed(int documentHandle)

  Description copied from interface: `DTM`
  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`
  Overrides:
    `isDocumentAllDeclarationsProcessed` in class `SimpleResultTreeImpl`

### isAttributeSpecified

    public boolean isAttributeSpecified(int attributeHandle)

  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).
