    Description

      • @CustomShadowVariable must be able to accept a class implementing the ListVariableListener interface.
      • ListVariableListener will be moved to the org.optaplanner.core.api.domain.variable package.
      • before/after list variable changed methods will be promoted to ScoreDirector to enable custom moves that modify list variables.
      • Checks must be put in place to fail fast if a custom EvilListMove breaks the disjoint list invariant.
      • IncrementalScoreCalculator should mimic the listener/director API as well (PLANNER-2711).

          Task - Represents a small unit of work that is not end-user facing. PLANNER-2830 Remove @CustomShadowVariable

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
