Method Detail

call

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

Evaluate this function call at run-time

Parameters:

context - The XPath dynamic evaluation context

arguments - The values of the arguments to the function call.

Returns:

the results of the function.

Throws:

XPathException - if a dynamic error occurs during evaluation of the function. The Saxon run-time code will add information about the error location.
