Member Function Documentation

virtual FunctionLang* FunctionLang::clone

(

MemoryManagerType &

theManager

)

const [virtual]

Create a copy of the function object.

Returns:

pointer to the new object

Implements Function.

virtual XObjectPtr FunctionLang::execute	(	XPathExecutionContext &	executionContext,
		XalanNode *	context,
		const XObjectPtr	arg,
		const LocatorType *	locator
	)		const [virtual]

Execute an XPath function object.

The function must return a valid object. Called if function has one parameter.

Parameters:

executionContext	executing context
context	current context node
arg	pointer to XObject argument
locator	LocatorType instance for the XPath expression that contains the function call

Returns:

pointer to the result XObject

Reimplemented from Function.

virtual const XalanDOMString& FunctionLang::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.

static void FunctionLang::initialize

(

MemoryManagerType &

theManager

)

[static]

Perform static initialization.

See class XPathInit.

static void FunctionLang::terminate

(

)

[static]

Perform static shut down.

See class XPathInit.
