Constructor & Destructor Documentation

ExtensionNSHandler::ExtensionNSHandler ( const XalanDOMString & namespaceUri,

MemoryManagerType & theManager )

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 ( MemoryManagerType & theManager,

const XalanDOMString & namespaceUri,

const XalanDOMString & elemNames,

const XalanDOMString & funcNames,

const XalanDOMString & lang,

const XalanDOMString & srcURL,

const XalanDOMString & src )

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

srcURL value of src attribute (if any) - treated as a URL or a classname depending on the value of lang. If srcURL is not null, then scriptSrc is ignored.

scriptSrc the actual script code (if any)

Member Function Documentation

ExtensionNSHandler * ExtensionNSHandler::create ( const XalanDOMString & namespaceUri,

MemoryManagerType & theManager ) [static]

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 XalanQName & 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 & srcURL,

const 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

srcURL value of src attribute (if any) - treated as a URL or a classname depending on the value of lang. If srcURL is not null, then scriptSrc is ignored.

scriptSrc the actual script code (if any)

Reimplemented from 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.
