[news.eclipse.modeling.m2m] Re: How to distinguish several in- and out-m

[Marcos Didonet Del Fabro <marcos.didonet-del-fabro@xxxxxxxxxxxxxx>]

Hi,

in the guard, you can use the method allInstancesFrom, like this:

rule MultipleInput {
  from
    c : UML2!Class (UML2!Class.allInstancesFrom('IN')->exists ( e | e = c) )
  to
    ...
}

Concerning the output models, try to use different identifiers for the output metamodels, 
as shown in the example below:

create OUT : UML_OUT1, TRACE_OUT : UML_OUT2 from ...

rule MultipleOutput {
   ...
  to
    model1: UML_OUT1 (
  ),
  model2 : UML_OUT2 (
  )
}


Regards,

Marcos.
