  Specified by:

  setStartNode in interface DTMAxisIterator

  Overrides:

  setStartNode in class MultiValuedNodeHeapIterator

  Parameters:

  node - the context node

  Returns:

  A DTMAxisIterator set to the start of the iteration.

• next

  public int next()

  A DTMAxisIterator, which may or may not be the same as this iterator.

• getLast

  public int getLast()

  Returns the number of nodes in this iterator.

  Specified by:

  getLast in interface DTMAxisIterator

  Overrides:

  getLast in class DTMAxisIteratorBase
