Member Function Documentation

virtual FunctionID* FunctionID::clone

(

MemoryManager &

theManager

)

const [virtual]

Create a copy of the function object.

Returns:

pointer to the new object

Implements Function.

virtual XObjectPtr FunctionID::execute	(	XPathExecutionContext &	executionContext,
		XalanNode *	context,
		const XObjectPtr	arg,
		const Locator *	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	Locator instance for the XPath expression that contains the function call

Returns:

pointer to the result XObject

Reimplemented from Function.

virtual const XalanDOMString& FunctionID::getError

(

XalanDOMString &

theBuffer

)

const [protected, virtual]

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

Parameters:

theBuffer

The XalanDOMString for the message.

Returns:

The error message

Implements Function.
