```
public SequenceEstimator(Director director)
```
    Construct an estimator for the given director.
    
    Parameters:
    
    director - The director that needs to guess a schedule.

```
public abstract java.util.Vector<Actor> estimateSequencedSchedule(java.util.List<SequenceAttribute> independentList)
                                                           throws NotSchedulableException
```
    Estimate a sequenced schedule.
    
    Parameters:
    
    independentList - The already present SequenceAttributes for the Actors controlled by this scheduler.
    
    Returns:
    
    A vector with the ordered actors. Note that the sequence numbers are not changed. This has to be done somewhere else.
    
    Throws:
    
    NotSchedulableException - If the underlying graph of the actors is not acyclic.
