createUndoMove(ScoreDirector<Solution_> 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<Solution_> 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.

isMoveDoable(ScoreDirector<Solution_> scoreDirector)

rebase(ScoreDirector<Solution_> destinationScoreDirector)
Rebases a move from an origin
ScoreDirector to another destination ScoreDirector
which is usually on another Thread or JVM. |

MovePlanningSolution.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.

MoveScoreDirector to another destination ScoreDirector
which is usually on another Thread or JVM.
The new move returned by this method mutates the entities and problem facts
of the destination PlanningSolution of the destination ScoreDirector,
That destination PlanningSolution should be a deep planning clone (or an even deeper clone)
of the origin PlanningSolution that this move was generated from.
That new move does the exact same change as this move,
resulting in the same PlanningSolution state,
presuming that destination PlanningSolution was in the same state
as the original PlanningSolution to begin with.
Generally speaking, an implementation of this method iterates through every entity and fact instance in this move,
translates each one to the destination ScoreDirector with ScoreDirector.lookUpWorkingObject(Object)
and creates a new move instance of the same move type, using those translated instances.
destinationScoreDirector - never null, the ScoreDirector.getWorkingSolution()

Duplicate 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.
