    Returns a name for use in messages.

  - hasNext
```
public boolean hasNext()
```
    Description copied from class: BoxHolder
    
    Checks if any more subboxes are available. This class doesn't fully conform to the Iterator interface, as there are some cases where the lack of more boxes won't be detected till an EOF is encounterd. So callers should call hasNext to avoid reading overruns, and then test the value returned by next for nullity.
    
    Specified by:
    
    hasNext in interface Iterator<Object>
    
    Overrides:
    
    hasNext in class BoxHolder
