  • Constructor Details

    • PrecedingEnumeration

      public PrecedingEnumeration(NodeInfo start, boolean includeAncestors)
      Create an iterator for the preceding or "preceding-or-ancestor" axis (the latter being used internall to support xsl:number)
      Parameters:
      start - the initial context node
      includeAncestors - true if ancestors of the initial context node are to be included in the result

    • next

      public final 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.
