Member Function Documentation

◆ clone()

virtual FunctionLang* xalanc::FunctionLang::clone ( MemoryManager &  theManager) const
virtual

Create a copy of the function object.

Returns
pointer to the new object

Implements xalanc::Function.

◆ execute() [1/6]

virtual XObjectPtr xalanc::Function::execute

Execute an XPath function object.

The function must return a valid object. Called if function has no parameters.

Parameters
executionContextexecuting context
contextcurrent context node
locatorLocator instance for the XPath expression that contains the function call
Returns
pointer to the result XObject

◆ execute() [2/6]

virtual XObjectPtr xalanc::Function::execute

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
executionContextexecuting context
contextcurrent context node
argsvector of pointers to XObject arguments
locatorLocator instance for the XPath expression that contains the function call
Returns
pointer to the result XObject

◆ execute() [3/6]

virtual XObjectPtr xalanc::Function::execute

Execute an XPath function object.

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

Parameters
executionContextexecuting context
contextcurrent context node
argpointer to XObject argument
locatorLocator instance for the XPath expression that contains the function call
Returns
pointer to the result XObject

◆ execute() [4/6]

virtual XObjectPtr xalanc::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
executionContextexecuting context
contextcurrent context node
argpointer to XObject argument
locatorLocator instance for the XPath expression that contains the function call
Returns
pointer to the result XObject

Reimplemented from xalanc::Function.

◆ execute() [5/6]

virtual XObjectPtr xalanc::Function::execute

Execute an XPath function object.

The function must return a valid object. Called if function has two parameters.

Parameters
executionContextexecuting context
contextcurrent context node
arg1pointer to XObject argument
arg2pointer to XObject argument
locatorLocator instance for the XPath expression that contains the function call
Returns
pointer to the result XObject

◆ execute() [6/6]

virtual XObjectPtr xalanc::Function::execute

Execute an XPath function object.

The function must return a valid object. Called if function has three parameters.

Parameters
executionContextexecuting context
contextcurrent context node
arg1pointer to XObject arguments
arg2pointer to XObject argument
arg3pointer to XObject argument
locatorLocator instance for the XPath expression that contains the function call
Returns
pointer to the result XObject

◆ getError()

virtual const XalanDOMString& xalanc::FunctionLang::getError ( XalanDOMString theBuffer) const
protectedvirtual

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

Parameters
theBufferThe XalanDOMString for the message.
Returns
The error message

Implements xalanc::Function.

◆ initialize()

static void xalanc::FunctionLang::initialize ( MemoryManager &  theManager)
static

Perform static initialization.

See class XPathInit.

◆ terminate()

static void xalanc::FunctionLang::terminate ( )
static

Perform static shut down.

See class XPathInit.
