Annotation Type ProblemFactProperty

Deprecated.

In favor of ProblemFactProperty.

public @interface ProblemFactProperty

Specifies that a property (or a field) on a PlanningSolution class is a problem fact. A problem fact must not change during solving (except through a ProblemFactChange event).

The constraints in a ConstraintProvider rely on problem facts for ConstraintFactory.from(Class). Alternatively, scoreDRL relies on problem facts too.

Do not annotate a planning entity or a planning paramerization as a problem fact: they are automatically available as facts for ConstraintFactory.from(Class) or DRL.
