evaluate
public AtomicValue evaluate(Item arg, XPathContext context)
Description copied from class:ScalarSystemFunctionAbstract method that must be supplied in subclasses to perform the evaluation- Specified by:
evaluatein classScalarSystemFunction- Parameters:
arg- the supplied argumentcontext- the dynamic context- Returns:
- the result of the evaluation
-
resultWhenEmpty
public One resultWhenEmpty()
Description copied from class:ScalarSystemFunctionMethod 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:
resultWhenEmptyin classScalarSystemFunction- Returns:
- the result of evaluation when the supplied argument is an empty sequence
-
getCompilerName
public java.lang.String getCompilerName()
Description copied from class:SystemFunctionGet the (local) name of a class that can be used to generate bytecode for this system function- Overrides:
getCompilerNamein classSystemFunction- Returns:
- the name of a bytecode generation class, or null if there is no bytecode support for this function
