```
public void yield(K key)
```
    Called by the iterator when a next or seek call yields control.
    
    Parameters:
    
    key - the key position at which the iterator yielded.
  - hasYielded
```
public boolean hasYielded()
```
    Called by the client to see if the iterator yielded
    
    Returns:
    
    true if iterator yielded control
  - getPositionAndReset
```
public K getPositionAndReset()
```
    Called by the client to get the yield position used as the start key (non-inclusive) of the range in a subsequent seek call when the iterator is rebuilt. This will also reset the state returned by hasYielded.
    
    Returns:
    
    K The key position
