public class PartialApplyFn
extends SystemFunction

This class implements the function fn:partial-apply(), which is a standard function in XQuery 3.1. The fn:apply function is also used internally to implement dynamic function calls.

Method Details

call

public Sequence call(XPathContext context,
 Sequence[] arguments)
              throws XPathException

Evaluate the expression

Parameters:

context - the dynamic evaluation context

arguments - the values of the arguments. The first argument is the function item to be called; the second argument is a map containing the arguments to be bound in that function, before conversion.

Returns:

the result of the evaluation, in the form of a SequenceIterator

Throws:

XPathException - if a dynamic error occurs during the evaluation of the expression
