evaluate
Description copied from class:ScalarSystemFunction
Abstract method that must be supplied in subclasses to perform the evaluation- Specified by:
evaluate
in classScalarSystemFunction
- Parameters:
item
- the supplied argumentcontext
- the dynamic context- Returns:
- the result of the evaluation
- Throws:
XPathException
- if a dynamic error occurs
-
resultWhenEmpty
Description copied from class:ScalarSystemFunction
Method that may be supplied in subclasses, to indicate the result that is returned when an empty sequence is supplied as the argument value. The default is to return the empty sequence- Overrides:
resultWhenEmpty
in classScalarSystemFunction
- Returns:
- the result of evaluation when the supplied argument is an empty sequence
-
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
