Method Detail

### setStartNode

    public DTMAxisIterator setStartNode(int node)

  Set context node for the iterator. This will cause the iterator to reset itself, reevaluate arguments to the function, look up nodes in the input and reinitialize its internal heap.
  Parameters:
    `node` - the context node
  Returns:
    A `DTMAxisIterator` set to the start of the iteration.
  Overrides:
    setStartNode in class MultiValuedNodeHeapIterator

### next

    public int next()

  Get the next node in the iteration.
  Returns:
    The next node handle in the iteration, or END.
  Overrides:
    next in class MultiValuedNodeHeapIterator

### reset

    public DTMAxisIterator reset()

  Resets the iterator to the last start node.
  Returns:
    A DTMAxisIterator, which may or may not be the same as this iterator.
  Overrides:
    reset in class MultiValuedNodeHeapIterator

### getLast

    public int getLast()

  Returns the number of nodes in this iterator.
  Returns:
    the number of nodes
  Overrides:
    getLast in class DTMAxisIteratorBase

### getNodeByPosition

    public int getNodeByPosition(int position)

  Return the node at the given position.
  Parameters:
    `position` - The position
  Returns:
    The node at the given position.
  Overrides:
    getNodeByPosition in class DTMAxisIteratorBase
