Method Detail

evaluate

public AtomicValue evaluate(Item arg,
                            XPathContext context)
                     throws XPathException

Description copied from class: ScalarSystemFunction

Abstract method that must be supplied in subclasses to perform the evaluation

Specified by:

evaluate in class ScalarSystemFunction

Parameters:

arg - the supplied argument

context - the dynamic context

Returns:

the result of the evaluation

Throws:

XPathException - if a dynamic error occurs

resultWhenEmpty

public ZeroOrOne<? extends AtomicValue> 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 class ScalarSystemFunction

Returns:

the result of evaluation when the supplied argument is an empty sequence
