Interface PlanningCloneable<T>

public interface PlanningCloneable<T>

Tagging interface for a Solution that implements its own planning cloning instead of letting the default or a custom SolutionCloner do it.

Planning cloning is hard: avoid doing it yourself.

Method Detail

planningClone

T planningClone()

Does a planning clone. A returned Solution 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 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 Solution, the original Solution must remain unchanged.

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

Returns:

never null, the cloned Solution
