protected Director _director

The director that controls the execution of the actors to be sequenced.

Constructor Detail

SequenceEstimator

public SequenceEstimator(Director director)

Construct an estimator for the given director.

Parameters:

director - The director that needs to guess a schedule.

Method Detail

estimateSequencedSchedule

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.
