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). |

Returns all planning entities that are being changed by this move.

Returns all planning values that entities are being assigned to by this move.

public boolean isMoveDoable(ScoreDirector scoreDirector)
MoveSolution.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.

Duplicates entries in the returned Collection are best avoided.
The returned Collection is recommended to be in a stable order.
For example: use List or LinkedHashSet, but not HashSet.
