Member Function Documentation

virtual bool XPathEnvSupport::elementAvailable	(	const XalanDOMString &	theNamespace,
		const XalanDOMString &	elementName
	)		const

pure virtual

Determine if an external element is available.

Parameters

theNamespace	namespace for the element
elementName	name of extension element

Returns: whether the element is available or not

Implemented in XPathEnvSupportDefault, XSLTProcessorEnvSupportDefault, and XSLTProcessorEnvSupport.

virtual XObjectPtr XPathEnvSupport::extFunction	(	XPathExecutionContext &	executionContext,
		const XalanDOMString &	theNamespace,
		const XalanDOMString &	functionName,
		XalanNode *	context,
		const XObjectArgVectorType &	argVec,
		const LocatorType *	locator
	)		const

pure virtual

Handle an extension function.

Parameters

executionContext	current execution context
theNamespace	namespace of function
functionName	extension function name
argVec	vector of arguments to function
locator	A LocatorType instance for error reporting.

Returns: pointer to XObject result

Implemented in XPathEnvSupportDefault, XSLTProcessorEnvSupportDefault, and XSLTProcessorEnvSupport.

virtual const XalanDOMString& XPathEnvSupport::findURIFromDoc ( const XalanDocument * owner ) const

pure virtual

Given a DOM Document, tell what URI was used to parse it.

Needed for relative resolution.

Parameters

owner source document

Returns: document URI

Implemented in XPathEnvSupportDefault, XSLTProcessorEnvSupportDefault, and XSLTProcessorEnvSupport.

virtual bool XPathEnvSupport::functionAvailable	(	const XalanDOMString &	theNamespace,
		const XalanDOMString &	functionName
	)		const

pure virtual

Determine if a function is available.

For standard function availability, theNamespace should be an empty string.

Parameters

theNamespace	namespace for the function
functionName	name of the function

Returns: whether the function is available or not

Implemented in XPathEnvSupportDefault, XSLTProcessorEnvSupportDefault, and XSLTProcessorEnvSupport.

virtual XalanDocument* XPathEnvSupport::getSourceDocument ( const XalanDOMString & theURI ) const

pure virtual

Get the source document for the given URI.

Parameters

theURI document URI

Returns: source document

Implemented in XPathEnvSupportDefault, XSLTProcessorEnvSupportDefault, and XSLTProcessorEnvSupport.

virtual XalanDocument* XPathEnvSupport::parseXML	(	MemoryManagerType &	theManager,
		const XalanDOMString &	urlString,
		const XalanDOMString &	base
	)

pure virtual

Provides support for XML parsing service.

Parameters

urlString	location of the XML
base	base location for URI

Returns: parsed document

Implemented in XPathEnvSupportDefault, XSLTProcessorEnvSupportDefault, and XSLTProcessorEnvSupport.

virtual bool XPathEnvSupport::problem	(	eSource	where,
		eClassification	classification,
		const PrefixResolver *	resolver,
		const XalanNode *	sourceNode,
		const XalanDOMString &	msg,
		const XalanDOMChar *	uri,
		int	lineNo,
		int	charOffset
	)		const

pure virtual

Function that is called when a problem event occurs.

Parameters

where	either eXMLParser, eXSLTProcessor, eXPATHParser, eXPATHProcessor, or eDataSource.
classification	either eWarning, or eError
resolver	resolver for namespace resolution
sourceNode	source tree node where the problem occurred (may be 0)
msg	string message explaining the problem.
uri	the URI of the stylesheet, if available. May be 0;
lineNo	line number where the problem occurred.
charOffset	character offset where the problem.
