`int` | `next()` Get the next node in the iteration.
`DTMAxisIterator` | `reset()` Resets the iterator to the last start node.
`void` | `setMark()` Remembers the current node for the next call to gotoMark().
`DTMAxisIterator` | `setStartNode(int node)` Set start to END should 'close' the iterator, i.e. subsequent call to next() should return END.

Constructor Detail

### SAX2DTM2.AncestorIterator

    public SAX2DTM2.AncestorIterator()

Method Detail

### getStartNode

    public int getStartNode()

  Get start to END should 'close' the iterator, i.e. subsequent call to next() should return END.

  Specified by:
    `getStartNode` in interface `DTMAxisIterator`
  Overrides:
    `getStartNode` in class `DTMAxisIteratorBase`
  Returns:
    The root node of the iteration.

### isReverse

    public final boolean isReverse()

  True if this iterator has a reversed axis.

  Specified by:
    `isReverse` in interface `DTMAxisIterator`
  Overrides:
    `isReverse` in class `DTMAxisIteratorBase`
  Returns:
    true since this iterator is a reversed axis.

### cloneIterator

    public DTMAxisIterator cloneIterator()

  Returns a deep copy of this iterator. The cloned iterator is not reset.

  Specified by:
    `cloneIterator` in interface `DTMAxisIterator`
  Overrides:
    `cloneIterator` in class `DTMAxisIteratorBase`
  Returns:
    a deep copy of this iterator.

### setStartNode

    public DTMAxisIterator setStartNode(int node)

  Set start to END should 'close' the iterator, i.e. subsequent call to next() should return END.

  Parameters:
    `node` - Sets the root of the iteration.
  Returns:
    A DTMAxisIterator set to the start of the iteration.

### reset

    public DTMAxisIterator reset()

  Resets the iterator to the last start node.

  Specified by:
    `reset` in interface `DTMAxisIterator`
  Overrides:
    `reset` in class `DTMAxisIteratorBase`
  Returns:
    A DTMAxisIterator, which may or may not be the same as this iterator.

### next

    public int next()

  Get the next node in the iteration.

  Returns:
    The next node handle in the iteration, or END.

### setMark

    public void setMark()

  Description copied from class: `DTMDefaultBaseIterators.InternalAxisIteratorBase`
  Remembers the current node for the next call to gotoMark(). %REVIEW% Should this save _position too?

  Specified by:
    `setMark` in interface `DTMAxisIterator`
  Overrides:
    `setMark` in class `DTMDefaultBaseIterators.InternalAxisIteratorBase`

### gotoMark

    public void gotoMark()

  Description copied from class: `DTMDefaultBaseIterators.InternalAxisIteratorBase`
  Restores the current node remembered by setMark(). %REVEIW% Should this restore _position too?

  Specified by:
    `gotoMark` in interface `DTMAxisIterator`
  Overrides:
    `gotoMark` in class `DTMDefaultBaseIterators.InternalAxisIteratorBase`
