getCardinality
Description copied from class:SystemFunction
Get the cardinality, given knowledge of the actual arguments- Overrides:
getCardinality
in classSystemFunction
- Parameters:
arguments
- the actual arguments supplied- Returns:
- the most precise available cardinality that the function will return
-
call
Evaluate the expression (used only for dynamic calls)- Parameters:
context
- the dynamic evaluation contextarguments
- the values of the arguments, supplied as Sequences- Returns:
- the result of the evaluation, in the form of a Sequence
- Throws:
XPathException
- if a dynamic error occurs during the evaluation of the expression
-
makeFunctionCall
Make an expression that either calls this function, or that is equivalent to a call on this function- Overrides:
makeFunctionCall
in classSystemFunction
- Parameters:
arguments
- the supplied arguments to the function call- Returns:
- either a function call on this function, or an expression that delivers the same result
