  • Constructor Details

    • EmptyTextFilter

      public EmptyTextFilter(AxisIterator base)
      Construct an EmptyTextFilter
      Parameters:

  • Method Details

    • next

      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.
