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.

AbstractMove.doMove(ScoreDirector) but without the ScoreDirector.triggerVariableListeners() call

scoreDirector
- never nullpublic ChainedSwapMove<Solution_> rebase(ScoreDirector<Solution_> destinationScoreDirector)
Move
ScoreDirector
to another destination ScoreDirector
which is usually on another Thread
or JVM.
The new move returned by this method translates the entities and problem facts
to the destination PlanningSolution
of the destination ScoreDirector
,
That destination PlanningSolution
is a deep planning clone (or an even deeper clone)
of the origin PlanningSolution
that this move has been 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.
The destination PlanningSolution
can be in a different state than the original PlanningSolution
.
So, rebasing can only depend on the identity of planning entities
and planning facts,
which is usually declared by a PlanningId
on those classes.
It must not depend on the state of the planning variables
.
One thread might rebase a move before, amid or after another thread does that same move instance.
This method is thread-safe.
