Constructor & Destructor Documentation

FunctionNodeSet::FunctionNodeSet

(

bool

convertString = true)

Constructor.

Parameters

convertString

If true, strings as well as result tree fragments will be converted to nodesets.

virtual FunctionNodeSet::~FunctionNodeSet ( )

virtual

Member Function Documentation

virtual FunctionNodeSet* FunctionNodeSet::clone ( MemoryManager &  theManager) const

virtual

Create a copy of the function object.

Returns

pointer to the new object

Implements Function.

Reimplemented in XalanEXSLTFunctionNodeSet.

virtual XObjectPtr FunctionNodeSet::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& FunctionNodeSet::getError ( XalanDOMString &  theBuffer) const

protectedvirtual

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.

Reimplemented in XalanEXSLTFunctionNodeSet.

virtual const XalanDOMString& FunctionNodeSet::getInvalidArgumentTypeError ( XalanDOMString &  theResult) const

protectedvirtual

Reimplemented in XalanEXSLTFunctionNodeSet.
