Method Detail

call

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

Evaluate the function

Parameters:

context - the dynamic evaluation context

arguments - 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
