Method Detail

cloneSolution

public SolutionG cloneSolution(SolutionG originalSolution)

Description copied from interface: SolutionCloner

Does a planning clone. The 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.

Specified by:

cloneSolution in interface SolutionCloner<SolutionG extends Solution>

Parameters:

originalSolution - never null, the original Solution

Returns:

never null, the cloned Solution
