Class AdaptiveResultTreeImpl
java.lang.Object
org.apache.xml.serializer.EmptySerializer
org.apache.xalan.xsltc.dom.SimpleResultTreeImpl
org.apache.xalan.xsltc.dom.AdaptiveResultTreeImpl
- All Implemented Interfaces:
- ContentHandler, DeclHandler, DOM, DOMSerializer, DTM, ErrorHandler, ExtendedContentHandler, ExtendedLexicalHandler, LexicalHandler, SerializationHandler, Serializer, XSLOutputAttributes
- 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.)

characters
public void characters(char[] ch,

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:

- This method is used to notify that an element is starting.
This method is just like the standard SAX method
startElement(uri,localName,qname,atts)
but without the attributes.

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:
- the Namespace URI;
- the local name; and
- 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

only the last parameter is passed. If needed the serializer can derive
the localName from the qualified name and derive the namespaceURI from
its implementation.

- 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.

A SAX parser must never report an XML declaration (XML 1.0,

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.

documentRelease
public void documentRelease()
- Description copied from interface:
DTM
