, this is not needed as the Solver
will do it for you.

- the ScoreDirector
not yet modified by the move.

not yet modified by the move.
public void doMove(ScoreDirector scoreDirector)
Move

accordingly.
When the Solution
is modified, the ScoreDirector
should be correctly notified,
otherwise later calculated Score
s can be corrupted.
scoreDirector
- never null, the ScoreDirector
that needs to get notified of the changes.protected boolean isRightValueLaterThanLeftEntity(Object anchor)
