Method Details

changeWorkingSolution

public void changeWorkingSolution(ScoreDirector<Object> scoreDirector)

Description copied from interface: CustomPhaseCommand

Changes working solution of ScoreDirector.getWorkingSolution(). When the working solution is modified, the ScoreDirector must be correctly notified (through ScoreDirector.beforeVariableChanged(Object, String) and ScoreDirector.afterVariableChanged(Object, String)), otherwise calculated Scores will be corrupted.

Don't forget to call ScoreDirector.triggerVariableListeners() after each set of changes (especially before every InnerScoreDirector.calculateScore() call) to ensure all shadow variables are updated.

Specified by:

changeWorkingSolution in interface CustomPhaseCommand<Object>

Parameters:

scoreDirector - never null, the ScoreDirector that needs to get notified of the changes.
