ExtensionNSHandler::ExtensionNSHandler ( const XalanDOMString & namespaceUri)

Construct a new extension namespace handler for a given extension NS.

This doesn't do anything - just hang on to the namespace URI.

Parameters:
namespaceUri   extension namespace URI being implemented

ExtensionNSHandler::ExtensionNSHandler ( const XalanDOMString & namespaceUri,
const XalanDOMString & elemNames,
const XalanDOMString & funcNames,
const XalanDOMString & lang,
const XalanDOMString & src="el" href="xal_cpp_vms_00112.html#a2">XalanDOMString & src="in">

Construct a new extension namespace handler given all the information needed.

Parameters:
namespaceUri   extension namespace URI being implemented
elemNames   string containing list of elements of extension NS
funcNames   string containing list of functions of extension NS
lang   language of code implementing the extension
src="a5" doxytag="ExtensionNSHandler::isElementAvailable">

bool ExtensionNSHandler::isElementAvailable ( const XalanDOMString & element) const

Tests whether a certain element name is known within this namespace.

Parameters:
element   name of the element being tested
Returns:
true if known, false if not

void ExtensionNSHandler::processElement ( StylesheetExecutionContext & executionContext,
const XalanDOMString & localPart,
const XalanElement * element,
Stylesheet & stylesheetTree,
const XalanNode * sourceTree,
const XalanNode * sourceNode,
const QName & mode)

Process a call to this extension namespace via an element.

As a side effect, the results are sent to the XSLTProcessor's result tree.

Parameters:
localPart   element name's local part
element   extension element being processed
stylesheetTree   compiled stylesheet tree
mode   current mode
sourceTree   root of the source tree (but don't assume it's a document)
sourceNode   current context node
Exceptions:
XSLProcessorException   thrown if something goes wrong while running the extension handler
MalformedURLException   if loading trouble
FileNotFoundException   if loading trouble
IOException   if loading trouble
SAXException   if parsing trouble

void ExtensionNSHandler::setElements ( const XalanDOMString & elemNames)

Set element local parts of extension NS.

Parameters:
elemNames   whitespace separated list of element names defined by this extension namespace

void ExtensionNSHandler::setFunctions ( const XalanDOMString & funcNames) [virtual]

Set function local parts of extension NS.

Super does the work; I just record that a component desc has been loaded.

Parameters:
functions   whitespace separated list of function names defined by this extension namespace

Reimplemented from ExtensionFunctionHandler.

void ExtensionNSHandler::setScript ( const XalanDOMString & lang,
const XalanDOMString & src="el" href="xal_cpp_vms_00112.html#a2">XalanDOMString & scriptSrc) [virtual]

Set the script data for this extension NS.

Deferred to super for actual work - only record that a component desc has been loaded.

Parameters:
lang   language of the script
src="el" href="class_extensionfunctionhandler.html#a4">ExtensionFunctionHandler.

void ExtensionNSHandler::startupComponent () [protected, virtual]

Start the component up by executing any script that needs to run at startup time.

This needs to happen before any functions can be called on the component.

Reimplemented from ExtensionFunctionHandler.
