[news.eclipse.modeling.m2m] [ATL] Re: Unsupported registration: QS

[William Piers <william.piers@xxxxxxx>]

Hello,

"QS" is the encoded type for Sequence(String), this warning indicates 
that ATL doesn't support Sequence as context for helpers.

You have to refactor the getSimilarity helper, for example it could be 
defined at the ATLModule level (e.g. as checkName):

helper def: getSimilarity(self_seq: Sequence(String), s : 
Sequence(String), sim : Integer) : Integer =
     if( self = '' or s = '') then
         sim
     else
         if( self_seq->first() = s->first()) then 
(self_seq->excluding(self->first())).getSimilarity(s->excluding(self_seq->first()),sim+1) 

          else
(self_seq->excluding(self_seq->first())).getSimilarity(s->excluding(self_seq->first()),sim) 

         endif
     endif;

Best regards,

William
