virtual XObjectPtr Function::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 in XalanEXSLTFunctionObjectType, XalanEXSLTFunctionDateTime, XalanEXSLTFunctionEvaluate, XalanEXSLTFunctionAbs, XalanEXSLTFunctionRandom, XalanEXSLTFunctionAcos, XalanEXSLTFunctionAsin, XalanEXSLTFunctionAtan, XalanEXSLTFunctionAtan2, XalanEXSLTFunctionConstant, XalanEXSLTFunctionCos, XalanEXSLTFunctionExp, XalanEXSLTFunctionHighest, XalanEXSLTFunctionLog, XalanEXSLTFunctionLowest, XalanEXSLTFunctionMax, XalanEXSLTFunctionMin, XalanEXSLTFunctionPower, XalanEXSLTFunctionSin, XalanEXSLTFunctionSqrt, XalanEXSLTFunctionTan, XalanEXSLTFunctionHasSameNode, XalanEXSLTFunctionLeading, XalanEXSLTFunctionTrailing, XalanEXSLTFunctionAlign, XalanEXSLTFunctionConcat, XalanEXSLTFunctionPadding, XalanEXSLTFunctionEncodeURI, XalanEXSLTFunctionDecodeURI, FunctionDifference, FunctionDistinct, FunctionEvaluate, FunctionHasSameNodes, FunctionIntersection, FunctionNodeSet, and FunctionConcat.

virtual XObjectPtr Function::execute ( XPathExecutionContext executionContext,
XalanNode context,
const LocatorType locator 
) const [virtual]

Execute an XPath function object.

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

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

Reimplemented in FunctionNamespaceURI, FunctionNormalizeSpace, FunctionString, FunctionCurrent, and FunctionGenerateID.

virtual XObjectPtr Function::execute ( XPathExecutionContext executionContext,
XalanNode context,
const XObjectPtr  arg,
const LocatorType 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 LocatorType instance for the XPath expression that contains the function call
Returns:
pointer to the result XObject

Reimplemented in FunctionID, FunctionLang, FunctionNamespaceURI, FunctionNormalizeSpace, FunctionString, FunctionDocument, FunctionElementAvailable, FunctionFunctionAvailable, FunctionGenerateID, FunctionSystemProperty, and FunctionUnparsedEntityURI.

virtual XObjectPtr Function::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 in FunctionConcat, FunctionContains, FunctionStartsWith, FunctionSubstring, FunctionSubstringAfter, FunctionSubstringBefore, FunctionDocument, FunctionFormatNumber, and FunctionKey.

virtual XObjectPtr Function::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 in FunctionConcat, FunctionSubstring, FunctionTranslate, and FunctionFormatNumber.
