getCardinality
Determine the cardinality of the function.- 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- 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
-
getCompilerName
Description copied from class:SystemFunction
Get the (local) name of a class that can be used to generate bytecode for this system function- Overrides:
getCompilerName
in classSystemFunction
- Returns:
- the name of a bytecode generation class, or null if there is no bytecode support for this function
