public abstract ANode next()
                    throws QueryException
```
    Description copied from class: Iter
    
    Returns the next item.
    
    Specified by:
    
    next in class Iter
    
    Returns:
    
    resulting item, or null if all items have been returned
    
    Throws:
    
    QueryException - query exception
  - get
```
public ANode get(long i)
```
    Description copied from class: Iter
    
    Returns the specified item, or an arbitrary item if the index is invalid. If this method returns items, Iter.size() needs to be implemented as well.
    
    Overrides:
    
    get in class Iter
    
    Parameters:
    
    i - value offset (starting with 0)
    
    Returns:
    
    specified item or null
  - size
```
public long size()
```
    Description copied from class: Iter
    
    Returns the iterator size. -1 is returned if the result size is unknown. If this method returns a positive value, Iter.get(long) needs to be implemented as well.
    
    Overrides:
    
    size in class Iter
    
    Returns:
    
    number of entries
