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

void StylesheetHandler::cdata ( const XMLCh *const ch,
const unsigned int 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

void StylesheetHandler::characters ( const XMLCh *const chars,
const unsigned int 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

void StylesheetHandler::charactersRaw ( const XMLCh *const chars,
const unsigned int 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  

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

Called when a Comment is to be constructed.

Parameters:
data   comment data
Exceptions:
SAXException  

void StylesheetHandler::doCleanup ( ) [protected]
 

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  

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  

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

Receive notification of a entityReference.

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

MemoryManagerType & StylesheetHandler::getMemoryManager ( )
 

void StylesheetHandler::ignorableWhitespace ( const XMLCh *const chars,
const unsigned int 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

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

Perform static initialization.

See class XMLSupportInit.

bool StylesheetHandler::isAttrOK ( const XalanDOMChar * attrName,
const AttributeListType & atts,
int 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 LocatorType * locator ) [protected]
 

Process xsl:import.

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

Process xsl:include.

bool StylesheetHandler::processSpaceAttr ( const XalanDOMChar * elementName,
const AttributeListType & atts,
const LocatorType * 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,
int which,
const LocatorType * 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.

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  

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.

void StylesheetHandler::setDocumentLocator ( const LocatorType *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

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  

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

void StylesheetHandler::terminate ( ) [static]
 

Perform static shut down.

See class XMLSupportInit.
