[flexcoders] Interface class for states?

[Van De Velde Hans]

Hi,
 
is there a way to use an interface class 
to define a minimum sets of states
in an MXML component?
 
For example, I need to be sure that every portlet (a component extending the
Canvas)
has at least these states:
 
  <mx:State name="minimized">
  </mx:State>
  <mx:State name="maximized">
  </mx:State>
  <mx:State name="normal">
  </mx:State>
  <mx:State name="icon">
  </mx:State>
  <mx:State name="edit">
  </mx:State>  

Is there a way to check for the presence of these states when compiling?
Like the implementation of an interface class checking for the presence of
certain methods.
 
 
Thanks,
Hans.
