    next in interface PrimitiveLongIterator
  - fetchNext
```
protected abstract boolean fetchNext()
```
    Fetches the next item in this iterator. Returns whether or not a next item was found. If a next item was found, that value must have been set inside the implementation of this method using next(long).
  - next
```
protected boolean next(long nextItem)
```
    Called from inside an implementation of fetchNext() if a next item was found. This method returns true so that it can be used in short-hand conditionals (TODO what are they called?), like:
    protected boolean fetchNext() { return source.hasNext() ? next( source.next() ) : false; }
    Parameters:
    
    nextItem - the next item found.
