      • lookUpWorkingObject

        <E> E lookUpWorkingObject​(E externalObject)
        Translates an entity or fact instance (often from another Thread or JVM) to this ScoreDirector's internal working instance. Useful for move rebasing and in a ProblemChange.

        Matching is determined by the LookUpStrategyType on PlanningSolution. Matching uses a PlanningId by default.

        Type Parameters:
        E - the object type
        Parameters:
        externalObject - sometimes null
        Returns:
        null if externalObject is null
        Throws:
        IllegalArgumentException - if there is no workingObject for externalObject, if it cannot be looked up or if the externalObject's class is not supported
        IllegalStateException - if it cannot be looked up

      • lookUpWorkingObjectOrReturnNull

        <E> E lookUpWorkingObjectOrReturnNull​(E externalObject)
        As defined by lookUpWorkingObject(Object), but doesn't fail fast if no workingObject was ever added for the externalObject. It's recommended to use lookUpWorkingObject(Object) instead, especially in move rebasing code.
        Type Parameters:
        E - the object type
        Parameters:
        externalObject - sometimes null
        Returns:
        null if externalObject is null or if there is no workingObject for externalObject
        Throws:
        IllegalArgumentException - if it cannot be looked up or if the externalObject's class is not supported
        IllegalStateException - if it cannot be looked up
