CustomPhaseCommand (OptaPlanner distribution 7.62.0.Final API)

Type Parameters:

Solution_ - the solution type, the class with the PlanningSolution annotation

All Known Implementing Classes:

AbstractCustomPhaseCommand, NoChangeCustomPhaseCommand

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface CustomPhaseCommand<Solution_>
```
Runs a custom algorithm as a Phase of the Solver that changes the planning variables. Do not abuse to change the problems facts, instead use Solver.addProblemFactChange(ProblemFactChange) for that.
An implementation must extend AbstractCustomPhaseCommand to ensure backwards compatibility in future versions.
To add custom properties, configure custom properties and add public setters for them.

Modifier and Type	Method	Description
`void`	`changeWorkingSolution(ScoreDirector<Solution_> scoreDirector)`	Changes `working solution` of `ScoreDirector.getWorkingSolution()`.

- Method Detail
  - changeWorkingSolution
```
void changeWorkingSolution(ScoreDirector<Solution_> scoreDirector)
```
    Changes working solution of ScoreDirector.getWorkingSolution(). When the working solution is modified, the ScoreDirector must be correctly notified (through ScoreDirector.beforeVariableChanged(Object, String) and ScoreDirector.afterVariableChanged(Object, String)), otherwise calculated Scores will be corrupted.
    Don't forget to call ScoreDirector.triggerVariableListeners() after each set of changes (especially before every ScoreDirector.calculateScore() call) to ensure all shadow variables are updated.
    
    Parameters:
    
    scoreDirector - never null, the ScoreDirector that needs to get notified of the changes.
