      All Methods Instance Methods Abstract Methods 
      Modifier and Type Method Description
      void add​(FONode newNode)
      Add the given newNode at the current position.
      FONode first()
      Returns the first node in the list, and decreases the index, so that a subsequent call to hasPrevious() will return false
      boolean hasNext()  
      boolean hasPrevious()  
      FONode last()
      Returns the last node in the list, and advances the current position, so that a subsequent call to hasNext() will return false
      FONode next()  
      int nextIndex()  
      FObj parent()
      Returns the parent node for this iterator's list of child nodes
      FONode previous()  
      int previousIndex()  
      void remove()
      Removes the node at the current position.
      void set​(FONode newNode)
      Replace the node at the current index with the given newNode.
