Member Function Documentation

virtual FunctionHasSameNodes* FunctionHasSameNodes::clone

(

MemoryManager &

theManager

)

const [virtual]

Create a copy of the function object.

Returns:

pointer to the new object

Implements Function.

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

Returns:

pointer to the result XObject

Reimplemented from Function.

virtual const XalanDOMString& FunctionHasSameNodes::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.
