List of cloneSolution() Examples

Examples of cloneSolution()

org.drools.planner.core.solution.Solution.cloneSolution()
Called by the {@link Solver} when the solution needs to be cloned,for example to store a clone of the current solution as the best solution.
A clone must also shallow copy the score. @return never null, a clone of which the properties that change during solving are deep cloned
org.optaplanner.core.api.domain.solution.cloner.SolutionCloner.cloneSolution()
Does a planning clone. The returned {@link 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 {@code 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 {@link Solution}, the original {@link Solution} must remain unchanged.
Note that a class might support more than 1 clone method: planning clone is just one of them. @param original never null, the original {@link Solution} @return never null, the cloned {@link Solution}

Examples of org.drools.planner.core.solution.Solution.cloneSolution()

        // At the end of the phase, the best solution should be in the working memory for the next phase
        // TODO WORKAROUND because the best solution might not be initialized yet (and than it's currently null)
        Solution bestSolution = solverScope.getBestSolution();
        if (bestSolution != null) {
            // Clone of bestSolution because next phase will change the working solution but might not improve best
            solverScope.getSolutionDirector().setWorkingSolution(bestSolution.cloneSolution());
        }
        termination.phaseEnded(solverPhaseScope);
        solverPhaseLifecycleSupport.firePhaseEnded(solverPhaseScope);
    }
