Detailed Description

This class processes a stylesheet via SAX events, and inits the given stylesheet.

If you need to alter the code in here, it is not for the faint-of-heart, due to the state tracking that has to be done due to the SAX event model.

Member Function Documentation

virtual void StylesheetHandler::cdata ( const XMLCh *const   ch,
const size_type  length 
) [virtual]

Receive notification of cdata.

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.

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

Parameters:
ch pointer to characters from the XML document
start start position in the array
length number of characters to read from the array
Exceptions:
SAXException 
See also:
ignorableWhitespace

Implements FormatterListener.

virtual void StylesheetHandler::characters ( const XMLCh *const   chars,
const size_type  length 
) [virtual]

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.

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

Parameters:
chars pointer to characters from the XML document
length number of characters to read from the array
Exceptions:
SAXException 
See also:
ignorableWhitespace
org.xml.sax.Locator

Implements FormatterListener.

virtual void StylesheetHandler::charactersRaw ( const XMLCh *const   chars,
const size_type  length 
) [virtual]

Receive notification of character data.

If available, when the disable-output-escaping attribute is used, output raw text without escaping.

Parameters:
ch pointer to characters from the XML document
start start position in the array
length number of characters to read from the array
Exceptions:
SAXException 

Implements FormatterListener.

virtual void StylesheetHandler::comment ( const XMLCh *const   data  )  [virtual]

Called when a Comment is to be constructed.

Parameters:
data comment data
Exceptions:
SAXException 

Implements FormatterListener.

void StylesheetHandler::doCleanup (  )  [protected]
virtual void StylesheetHandler::endDocument (  )  [virtual]

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.

Exceptions:
SAXException 

Implements FormatterListener.

virtual void StylesheetHandler::endElement ( const XMLCh *const   name  )  [virtual]

Receive notification of the end of an element.

The SAX parser will invoke this method at the end of every element in the XML document; there will be a corresponding startElement() event for every endElement() event (even when the element is empty).

If the element name has a namespace prefix, the prefix will still be attached to the name.

Parameters:
name element type name
Exceptions:
SAXException 

Implements FormatterListener.

virtual void StylesheetHandler::entityReference ( const XMLCh *const   data  )  [virtual]

Receive notification of a entityReference.

Parameters:
data pointer to characters from the XML document
Exceptions:
SAXException 

Implements FormatterListener.

MemoryManager& StylesheetHandler::getMemoryManager (  )  [inline]

Definition at line 103 of file StylesheetHandler.hpp.

virtual void StylesheetHandler::ignorableWhitespace ( const XMLCh *const   chars,
const size_type  length 
) [virtual]

Receive notification of ignorable whitespace in element content.

Validating Parsers must use this method to report each chunk of ignorable whitespace (see the W3C XML 1.0 recommendation, section 2.10): non-validating parsers may also use this method if they are capable of parsing and using content models.

SAX parsers may return all contiguous whitespace 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.

Parameters:
chars characters from the XML document
start start position in the array
length number of characters to read from the array
Exceptions:
SAXException 
See also:
characters

Implements FormatterListener.

static void StylesheetHandler::initialize ( MemoryManager &  theManager  )  [static]

Perform static initialization.

See class XMLSupportInit.

bool StylesheetHandler::isAttrOK ( const XalanDOMChar *  attrName,
const AttributeListType atts,
XalanSize_t  which 
) [protected]

See if this is a xmlns attribute, and, if so, process it.

Parameters:
attrName Qualified name of attribute.
atts The attribute list where the element comes from (not used at this time).
which The index into the attribute list (not used at this time).
Returns:
True if this is a namespace name.
void StylesheetHandler::processImport ( const XalanDOMChar *  name,
const AttributeListType atts,
const Locator *  locator 
) [protected]

Process xsl:import.

void StylesheetHandler::processInclude ( const XalanDOMChar *  name,
const AttributeListType atts,
const Locator *  locator 
) [protected]

Process xsl:include.

virtual void StylesheetHandler::processingInstruction ( const XMLCh *const   target,
const XMLCh *const   data 
) [virtual]

Receive notification of a processing instruction.

The Parser will invoke this method once for each processing instruction found: note that processing instructions may occur before or after the main document element.

A SAX parser should never report an XML declaration (XML 1.0, section 2.8) or a text declaration (XML 1.0, section 4.3.1) using this method.

Parameters:
target pointer to processing instruction target
data pointer to processing instruction data, or null if none was supplied
Exceptions:
SAXException 

Implements FormatterListener.

bool StylesheetHandler::processSpaceAttr ( const XalanDOMChar *  elementName,
const AttributeListType atts,
const Locator *  locator,
bool &  fPreserve 
) [protected]

Tell whether or not this is a xml:space attribute and, if so, process it.

Parameters:
elementName The name of the element that owns the attributes
atts The attribute list that owns the attribute.
locator A Locator instance for error reporting.
fPreserve set to true if an xml:space attribute value is "preserve"
Returns:
True if this is a xml:space attribute.
bool StylesheetHandler::processSpaceAttr ( const XalanDOMChar *  elementName,
const XalanDOMChar *  aname,
const AttributeListType atts,
XalanSize_t  which,
const Locator *  locator,
bool &  fPreserve 
) [protected]

Tell whether or not this is a xml:space attribute and, if so, process it.

Parameters:
elementName The name of the element that owns the attribute
aname The name of the attribute in question.
atts The attribute list that owns the attribute.
which The index of the attribute into the attribute list.
locator A Locator instance for error reporting.
fPreserve set to true if the attribute value is "preserve"
Returns:
True if this is a xml:space attribute.
virtual void StylesheetHandler::resetDocument (  )  [virtual]

This method allows the user installed Document Handler to 'reset' itself, freeing all the memory resources.

The scanner calls this method before starting a new parse event.

Implements FormatterListener.

virtual void StylesheetHandler::setDocumentLocator ( const Locator *const   locator  )  [virtual]

Receive an object for locating the origin of SAX document events.

SAX parsers are strongly encouraged (though not absolutely required) to supply a locator: if it does so, it must supply the locator to the application by invoking this method before invoking any of the other methods in the DocumentHandler interface.

The locator allows the application to determine the end position of any document-related event, even if the parser is not reporting an error. Typically, the application will use this information for reporting its own errors (such as character content that does not match an application's business rules). The information returned by the locator is probably not sufficient for use with a search engine.

Note that the locator will return correct information only during the invocation of the events in this interface. The application should not attempt to use it at any other time.

Parameters:
locator object that can return the location of any SAX document event.
See also:
org.xml.sax.Locator

Implements FormatterListener.

virtual void StylesheetHandler::startDocument (  )  [virtual]

Receive notification of the beginning of a document.

The SAX parser will invoke this method only once, before any other methods in this interface or in DTDHandler (except for setDocumentLocator).

Exceptions:
SAXException 

Implements FormatterListener.

virtual void StylesheetHandler::startElement ( const XMLCh *const   name,
AttributeListType attrs 
) [virtual]

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.

If the element name has a namespace prefix, the prefix will still be attached. Note that the attribute list provided will contain only attributes with explicit values (specified or defaulted): IMPLIED attributes will be omitted.

Parameters:
name element type name
atts attributes attached to the element, if any
Exceptions:
SAXException 
See also:
endElement
org.xml.sax.AttributeList
static void StylesheetHandler::terminate (  )  [static]

Perform static shut down.

See class XMLSupportInit.
