[jboss-dev-forums] [Design the new POJO MicroContainer] - ControllerStates helper/util

[alesj]

I'm thinking of introducing something like this

  | public class ControllerStates
  | {   
  |    public static ControllerState previousState(List<ControllerState> states, ControllerState state);
  |    
  |    public static int currentStateIndex(List<ControllerState> states, ControllerState state);
  |  
  |    public static ControllerState nextState(List<ControllerState> states, ControllerState state);
  | 
  |    ...
  | }
  | 
to handle this previous/next state lookup in a singe place.
Currently there is a bunch of code that does this, mostly w/o any constraints check, e.g. no such state in states.

I'll push it in org.jboss.dependency.spi.helpers package.
Or should/could this be on the ControllerState already?
