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.

- 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.)

throws org.xml.sax.SAXException
- Description copied from interface:
ExtendedContentHandler
- Add a unique attribute to the current element.
The attribute is guaranteed to be unique here. The serializer can write
it out immediately without saving it in a table first. The integer

java.lang.String uri)
throws org.xml.sax.SAXException
- 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")
- Specified by:
namespaceAfterStartElement
in interface ExtendedContentHandler
- Overrides:
namespaceAfterStartElement
in class EmptySerializer

- Description copied from interface:
DTM
- Given a node handle, test if it has child nodes.

getDocumentVersion
public java.lang.String getDocumentVersion(int documentHandle)
- Description copied from interface:
DTM

property is derived from the XML declaration optionally present at the
beginning of the document entity, and has no value if there is no XML
declaration.
- Specified by:
getDocumentVersion
in interface DTM
- Overrides:
getDocumentVersion
in class SimpleResultTreeImpl

documentHandle
- the document handle
- Returns:
- the document version String object
getDocumentAllDeclarationsProcessed
public boolean getDocumentAllDeclarationsProcessed()
- Description copied from interface:
DTM
- Return 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:
getDocumentAllDeclarationsProcessed
in interface DTM
- Overrides:
getDocumentAllDeclarationsProcessed
in class SimpleResultTreeImpl
- Returns:
true
if all declarations were processed;
false
otherwise.
getDocumentTypeDeclarationSystemIdentifier
public java.lang.String getDocumentTypeDeclarationSystemIdentifier()
- Description copied from interface:
DTM
- A document type declaration information item has the following properties:
1. [system identifier] The system identifier of the external subset, if
it exists. Otherwise this property has no value.
- Specified by:
getDocumentTypeDeclarationSystemIdentifier
in interface DTM
- Overrides:
getDocumentTypeDeclarationSystemIdentifier
in class SimpleResultTreeImpl
- Returns:
- the system identifier String object, or null if there is none.
getDocumentTypeDeclarationPublicIdentifier
public java.lang.String getDocumentTypeDeclarationPublicIdentifier()
- Description copied from interface:
DTM
- 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.
- Specified by:
getDocumentTypeDeclarationPublicIdentifier
in interface DTM
- Overrides:
getDocumentTypeDeclarationPublicIdentifier
in class SimpleResultTreeImpl
- Returns:
- the public identifier String object, or null if there is none.
getElementById
public int getElementById(java.lang.String elementId)
- Description copied from interface:
DTM
- 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
- Overrides:
getElementById
in class SimpleResultTreeImpl
- Parameters:
elementId
- The unique id
value for an element.
- Returns:
- The handle of the matching element.
supportsPreStripping
public boolean supportsPreStripping()

- Specified by:
supportsPreStripping
in interface DTM
- Overrides:
supportsPreStripping
in class SimpleResultTreeImpl
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
- Parameters:
firstNodeHandle
- DOM Node to perform position comparison on.secondNodeHandle
- DOM Node to perform position comparison on.
- Returns:
- false if secondNode comes before firstNode, otherwise return true.
You can think of this as
(firstNode.documentOrderPosition <= secondNode.documentOrderPosition)
.
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 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

- Overrides:
isAttributeSpecified
in class SimpleResultTreeImpl
- Parameters:
attributeHandle
- The attribute handle

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).
- Specified by:
appendChild
in interface DTM
- Overrides:
appendChild
in class SimpleResultTreeImpl
- Parameters:
newChild
- Must be a valid new node handle.clone
- true if the child should be cloned into the document.cloneDepth
- if the clone argument is true, specifies that the
clone should include all it's children.
appendTextChild
