[news.eclipse.modeling.m2m] Re: [ATL] OrderedSet.indexOf operation not found 
Hello,

This operation seems to be unimplemented, so it is a bug. Could you report it ?

Thanks in advance,

William

Hi,

I am working on an ATL template that has the following helper definition:

helper context OclAny def: getElementId() :
  String = 'http://openiaml.org/simple#test' +
    if simple!EObject.allInstancesFrom('IN')->includes(self)
    then simple!EObject.allInstancesFrom('IN')->indexOf(self)->toString()
    else 'unknown'
    endif;

The idea behind this template is that I can get a unique ID of an element based on its absolute position. However, if I use this against an EMF model, I get the following exception message:

Operation not found: OrderedSet {...}.indexOf(org.openiaml.model.owl.simple.simple.impl.InternetApplicationImpl)


If I instead convert this OrderedSet into a Sequence as follows, the ATL template works without any errors:


simple!EObject.allInstancesFrom('IN')->asSequence()->indexOf(self)->toString()


This wasn't expected, considering the ATL User Guide [1] says OrderedSet.indexOf(o : oclAny) is supported.

Is this expected behaviour? Is any EObject an oclAny? Or is this a problem with the documentation?

Thanks!

Jevon
