call
Description copied from class:FoldingFunction
Evaluate the expression- Specified by:
call
in interfaceCallable
- Overrides:
call
in classFoldingFunction
- 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
-
getFold
Create the Fold object which is used to perform a streamed evaluation- Specified by:
getFold
in classFoldingFunction
- Parameters:
context
- the dynamic evaluation contextadditionalArguments
- the values of all arguments other than the first.- Returns:
- the Fold object used to compute the function
