Public Member Functions

XalanEXSLTFunctionExp ()
virtual ~XalanEXSLTFunctionExp ()
virtual XObjectPtr execute (XPathExecutionContext &executionContext, XalanNode *context, const XObjectArgVectorType &args, const LocatorType *locator) const
Execute an XPath function object.
virtual XalanEXSLTFunctionExp * clone (MemoryManagerType &theManager) const
Create a copy of the function object.

Member Function Documentation

virtual XalanEXSLTFunctionExp* XalanEXSLTFunctionExp::clone ( MemoryManagerType & theManager ) const [virtual]

Create a copy of the function object.

Returns:
pointer to the new object

Implements Function.

virtual XObjectPtr XalanEXSLTFunctionExp::execute ( XPathExecutionContext & executionContext,

XalanNode * context,

const XObjectArgVectorType & args,

const LocatorType * locator

) const [virtual]

Execute an XPath function object.
The function must return a valid object. Extension functions should override this version of execute(), rather than one of the other calls designed for a specific number of arguments, since the extension function mechanism will call this version first. Extension functions that accept more than three arguments _must_ override this version.

Parameters:

executionContext executing context

context current context node

args vector of pointers to XObject arguments

locator LocatorType instance for the XPath expression that contains the function call

Returns:
pointer to the result XObject

Reimplemented from Function.

const XalanDOMString& XalanEXSLTFunctionExp::getError ( XalanDOMString & theBuffer ) const [protected, virtual]

Get the error message to report when the function is called with the wrong number of arguments.

Returns:
function error message

Implements Function.
