  - hasNext
```
public boolean hasNext()

    Specified by:
    
    hasNext in interface PrimitiveIntIterator
  - next
```
public int next()
```
    Specified by:
    
    next in interface PrimitiveIntIterator
  - 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(int).
  - next
```
protected boolean next(int 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:
    @Override protected boolean fetchNext() { return source.hasNext() ? next( source.next() ) : false; }
    Parameters:
    
    nextItem - the next item found.
