Method Detail

call

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

Create a call on this function. This method is called by the compiler when it identifies a function call that calls this function.

Parameters:

context - the XPath dynamic evaluation context

arguments - the actual arguments to be supplied

Returns:

an expression representing a call of this extension function

Throws:

XPathException - if a dynamic error occurs within the function

compareSortKeys

public static int compareSortKeys(GroundedValue a,
                                  GroundedValue b,
                                  AtomicComparer comparer)
