  • Constructor Details

    • AxisFilter

      public AxisFilter(AxisIterator base, NodeTest test)
      S Construct a AxisFilter
      Parameters:
      base - the underlying iterator that returns all the nodes on a required axis. This must not be an atomizing iterator!
      test - a NodeTest that is applied to each node returned by the underlying AxisIterator; only those nodes that pass the NodeTest are returned by the AxisFilter
  • Method Details

    • next

      public Item next()
      Description copied from interface: AxisIterator
      Get the next item in the sequence.
      Returns:
      the next Item. If there are no more nodes, return null.
    • getAnother

      public SequenceIterator getAnother()
      Description copied from interface: AxisIterator
      Get another iterator over the same sequence of items, positioned at the start of the sequence. It must be possible to call this method at any time, whether none, some, or all of the items in the original iterator have been read. The method is non-destructive: it does not change the state of the original iterator.
      Returns:
      a new iterator over the same sequence
