Move |
createUndoMove(ScoreDirector scoreDirector)
Called before the move is done, so the move can be evaluated and then be undone
without resulting into a permanent change in the solution.
|
protected void |
doMoveOnGenuineVariables(ScoreDirector scoreDirector)
Like
AbstractMove.doMove(ScoreDirector) but without the ScoreDirector.triggerVariableListeners() call
(because AbstractMove.doMove(ScoreDirector) already does that). |

getPlanningEntities()
Returns all planning entities that are being changed by this move.
|
Collection<? extends Object> |
getPlanningValues()
Returns all planning values that entities are being assigned to by this move.

Move
Solution
.It is recommended to keep this method implementation simple: do not use it in an attempt to satisfy normal hard and soft constraints.
Although you could also filter out non-doable moves in for example the MoveSelector
or MoveListFactory
, this is not needed as the Solver
will do it for you.
