Class PrecedingEnumeration
java.lang.Object
net.sf.saxon.tree.iter.AxisIteratorImpl
net.sf.saxon.tree.tiny.PrecedingEnumeration
- All Implemented Interfaces:
- SequenceIterator, AxisIterator, UnfailingIterator
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".

next
public Item next()
- Description copied from interface:
SequenceIterator
- Get the next item in the sequence. This method changes the state of the
iterator, in particular it affects the result of subsequent calls of
position() and current().
- Returns:
- the next item, or null if there are no more items. Once a call
on next() has returned null, no further calls should be made. The preferred
action for an iterator if subsequent calls on next() are made is to return
null again, and all implementations within Saxon follow this rule.
getAnother
public SequenceIterator getAnother()
- Get another enumeration of the same nodes
- Returns:
- a SequenceIterator that iterates over the same items,
positioned before the first item
