    - #### buildVariableListener

          public abstract VariableListener<?> buildVariableListener(InnerScoreDirector<Solution_> scoreDirector)

      Parameters:
        `scoreDirector` - never null
      Returns:
        never null

    - #### isGenuineAndUninitialized

          public boolean isGenuineAndUninitialized(Object entity)

      Specified by:
        `isGenuineAndUninitialized` in class `VariableDescriptor<Solution_>`

    - #### toString

          public String toString()
