question: public void reset ( ) { _unManagedVolumeUrisToProcessIterator = _unManagedVolumeUrisToProcess . iterator ( ) ; _currentUnManagedVolumeUri = null ; }
target:  Resets the UnManagedVolume iterator and sets the current UnManagedVolume back to null.  This allows iterating over the UnManagedVolumes in the request again.
