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

Returns:

never null

doMove

public final void doMove(ScoreDirector scoreDirector)

Description copied from interface: Move

Does the Move and updates the Solution and its ScoreDirector accordingly. When the Solution is modified, the ScoreDirector should be correctly notified, otherwise later calculated Scores can be corrupted.

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

Specified by:

doMove in interface Move

Parameters:

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

doMoveOnGenuineVariables

protected abstract void doMoveOnGenuineVariables(ScoreDirector scoreDirector)

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

Parameters:

scoreDirector - never null
