             Summary: Planner: Custom move implementations shouldn't need to call before and after
                 Key: JBRULES-3472
                 URL: https://issues.jboss.org/browse/JBRULES-3472
             Project: Drools
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: drools-planner
            Reporter: Geoffrey De Smet
            Assignee: Geoffrey De Smet


Is this idea feasible?

We merge
- ScoreDirector.beforeVariableChanged(Object entity, String variableName)
- ScoreDirector.afterVariableChanged(Object entity, String variableName)
Into
- ScoreDirector.afterVariableChanged(Object entity, String variableName, Object oldValue, Object newValue)

Then, in a custom Move.doMove() implementation we need to call neither because Planner can figure it out:
- Call Move.getPlanningEntities() before calling doMove(), which returns all entities
- For each variable on every entity:
-- If the value before and after has changed, notify the ScoreDirector

What about Move's that add or remove entities?
