All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`Item`	`current()`	Get the current item in the sequence.
`SequenceIterator`	`getAnother()`	Get another iterator over the same sequence of items, positioned at the start of the sequence.
`Item`	`next()`	Get the next item in the sequence.

- Method Detail
  - next
```
Item next()
```
    Get the next item in the sequence.
    
    Specified by:
    
    next in interface SequenceIterator
    
    Returns:
    
    the next Item. If there are no more nodes, return null.
  - current
```
Item current()
```
    Get the current item in the sequence.
    
    Specified by:
    
    current in interface SequenceIterator
    
    Returns:
    
    the current item, that is, the item most recently returned by next()
  - position
```
int position()
```
    Get the current position
    
    Specified by:
    
    position in interface SequenceIterator
    
    Returns:
    
    the position of the current item (the item most recently returned by next()), starting at 1 for the first node
  - getAnother
```
SequenceIterator getAnother()
```
    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.
    
    Specified by:
    
    getAnother in interface SequenceIterator
    
    Returns:
    
    a new iterator over the same sequence
