Class XPathAxe

java.lang.Object

com.saxonica.functions.qt4.ixml.XPathAxe

All Implemented Interfaces:

org.nineml.coffeegrinder.trees.Axe

public class XPathAxe
extends Object
implements org.nineml.coffeegrinder.trees.Axe

The Axe used by CoffeeSacks to choose between ambiguous alternatives.

At the moment, this is not a specialist axe. To implement more general selections (random ones, for example), some provision would have to be made for creating either a "normal" or a specialist axe. TBD.
