Class PrecedingEnumeration

java.lang.Object

net.sf.saxon.om.AxisIteratorImpl

net.sf.saxon.tinytree.PrecedingEnumeration

All Implemented Interfaces:

AtomizableIterator, AxisIterator, SequenceIterator

final class PrecedingEnumeration
extends AxisIteratorImpl

Enumerate all the nodes on the preceding axis from a given start node. The calling code ensures that the start node is not a root, attribute, or namespace node. As well as the standard XPath preceding axis, this class also implements a Saxon-specific "preceding-or-ancestor" axis which returns ancestor nodes as well as preceding nodes. This is used when performing xsl:number level="any".
