Method Detail

getSimpleMoveTypeDescription

public String getSimpleMoveTypeDescription()

Description copied from interface: Move

Describes the move type for statistical purposes. For example "ChangeMove(Process.computer)".

The format is not formalized. Never parse the String returned by this method.

Specified by:

getSimpleMoveTypeDescription in interface Move<Solution_>

Returns:

never null

doMove

public final void doMove(ScoreDirector<Solution_> scoreDirector)

Description copied from interface: Move

Does the move (which indirectly affects the ScoreDirector.getWorkingSolution()). When the working solution is modified, the ScoreDirector must be correctly notified (through ScoreDirector.beforeVariableChanged(Object, String) and ScoreDirector.afterVariableChanged(Object, String)), otherwise later calculated Scores will be corrupted.

This method must end with calling ScoreDirector.triggerVariableListeners() to ensure all shadow variables are updated.

Specified by:

doMove in interface Move<Solution_>

Parameters:

scoreDirector - never null, the ScoreDirector that needs to get notified of the changes.

doMoveOnGenuineVariables

protected abstract void doMoveOnGenuineVariables(ScoreDirector<Solution_> scoreDirector)

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

Parameters:

scoreDirector - never null
