Class PrecedingIterator

java.lang.Object
net.sf.saxon.tree.tiny.PrecedingIterator
All Implemented Interfaces:
Closeable, AutoCloseable, SequenceIterator, AxisIterator

final class PrecedingIterator extends Object implements AxisIterator
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".

      public NodeInfo next()
      Description copied from interface: SequenceIterator
      Get the next item in the sequence. This method changes the state of the iterator.
      Specified by:
      next in interface AxisIterator
      Specified by:
      next in interface SequenceIterator
      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.
