Class PrecedingOrAncestorEnumeration

java.lang.Object

net.sf.saxon.tree.linked.TreeEnumeration

net.sf.saxon.tree.linked.PrecedingOrAncestorEnumeration

All Implemented Interfaces:

SequenceIterator, AxisIterator, LookaheadIterator, UnfailingIterator

final class PrecedingOrAncestorEnumeration
extends TreeEnumeration

This axis cannot be requested directly in an XPath expression but is used when evaluating xsl:number. It is provided because taking the union of the two axes would be very inefficient
