Method Details

doMoveOnGenuineVariables

protected void doMoveOnGenuineVariables(ScoreDirector<Solution_> scoreDirector)

Deprecated, for removal: This API element is subject to removal in a future version.

Description copied from class: AbstractMove

Like AbstractMove.doMoveOnly(ScoreDirector) but without the ScoreDirector.triggerVariableListeners() call (because AbstractMove.doMoveOnly(ScoreDirector) already does that).

Overrides:

doMoveOnGenuineVariables in class SwapMove<Solution_>

Parameters:

scoreDirector - never null

rebase

public ChainedSwapMove<Solution_> rebase(ScoreDirector<Solution_> destinationScoreDirector)

Deprecated, for removal: This API element is subject to removal in a future version.

Description copied from interface: Move

Rebases a move from an origin 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 problem facts, which are 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.

Specified by:

rebase in interface Move<Solution_>

Overrides:

rebase in class SwapMove<Solution_>

Parameters:

destinationScoreDirector - never null, the ScoreDirector.getWorkingSolution() that the new move should change the planning entity instances of.

Returns:

never null, a new move that does the same change as this move on another solution instance
