Member Function Documentation

virtual FunctionLang* FunctionLang::clone ( MemoryManager &  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 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& FunctionLang::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.

static void FunctionLang::initialize ( MemoryManager &  theManager )

static

Perform static initialization.

See class XPathInit.

static void FunctionLang::terminate ( )

static

Perform static shut down.

See class XPathInit.
