Method Detail

cloneSolution

public Solution_ cloneSolution(Solution_ originalSolution)

Description copied from interface: SolutionCloner

Does a planning clone. The returned PlanningSolution clone must fulfill these requirements:

• The clone must represent the same planning problem. Usually it reuses the same instances of the problem facts and problem fact collections as the original.
• The clone must have the same (equal) score as the original.
• The clone must use different, cloned instances of the entities and entity collections. If a cloned entity changes, the original must remain unchanged. If an entity is added or removed in a cloned PlanningSolution, the original PlanningSolution must remain unchanged.

Note that a class might support more than 1 clone method: planning clone is just one of them.

This method is thread-safe.

Specified by:

cloneSolution in interface SolutionCloner<Solution_>

Parameters:

originalSolution - never null, the original PlanningSolution

Returns:

never null, the cloned PlanningSolution

gizmoFallbackDeepClone

public Object gizmoFallbackDeepClone(Object originalValue,
                                     Map<Object,Object> originalToCloneMap)

Used by GIZMO when it encounters an undeclared entity class, such as when an abstract planning entity is extended.
