Member Function Documentation

virtual FunctionConcat* FunctionConcat::clone (  MemoryManagerType &  theManager  )  const [virtual]
 

Create a copy of the function object.

Returns:
pointer to the new object

Implements Function.

XObjectPtr FunctionConcat::execute (  XPathExecutionContext &  executionContext,
XalanNode *  context,
const XObjectPtr  arg1,
const XObjectPtr  arg2,
const XObjectPtr  arg3,
const LocatorType *  locator
)  const [virtual]
 

Execute an XPath function object.

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

Parameters:
executionContext executing context
context current context node
arg1 pointer to XObject arguments
arg2 pointer to XObject argument
arg3 pointer to XObject argument
locator LocatorType instance for the XPath expression that contains the function call
Returns:
pointer to the result XObject

Reimplemented from Function.

XObjectPtr FunctionConcat::execute (  XPathExecutionContext &  executionContext,
XalanNode *  context,
const XObjectPtr  arg1,
const XObjectPtr  arg2,
const LocatorType *  locator
)  const [virtual]
 

Execute an XPath function object.

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

Parameters:
executionContext executing context
context current context node
arg1 pointer to XObject argument
arg2 pointer to XObject argument
locator LocatorType instance for the XPath expression that contains the function call
Returns:
pointer to the result XObject

Reimplemented from Function.

virtual XObjectPtr FunctionConcat::execute (  XPathExecutionContext &  executionContext,
XalanNode *  context,
const XObjectArgVectorType &  args,
const LocatorType *  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 LocatorType instance for the XPath expression that contains the function call
Returns:
pointer to the result XObject

Reimplemented from Function.

virtual const XalanDOMString& FunctionConcat::getError (  XalanDOMString &  theResult  )  const [protected, virtual]
 

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

Returns:
function error message

Implements Function.
