Examples of ProblemFactChange

org.drools.planner.core.solver.ProblemFactChange
A ProblemFactChange represents a change in 1 or more problem facts of a {@link Solution}. Problem facts used by a {@link Solver} must not be changed while it is solving,but by scheduling this command to the {@link Solver}, you can change them when the time is right.
Note that the {@link Solver} clones a {@link Solution} at will.So any change must be done on the problem facts and planning entities referenced by the {@link Solution}of the {@link ScoreDirector}. On each change it should also notify the {@link ScoreDirector} accordingly.
