[Acceleo] allInstances operator not available? [message #1810881] Wed, 21 August 2019 09:55 Go to next message

Hi,

I have a hard time using the allInstances() operator. In a Sirius editor I try to select all instances of a specific class via aql. The documentation of https://www.eclipse.org/acceleo/documentation/ indicates that something similimar to the following should be possible:

aql:basicfamily::Women.allInstances()

Unfortunately, this does not work. I have tried several variants of this but did not succeed. Is there something I am missing? I simply want to grep all instances of the class "Women", which are in my model.

Best regards and thank you in advance,
Nico

Hi

Within Sirius you may use AQL which is an OCL-like language. In OCL basicfamily::Women::allInstances() could work, provided you are using the correct ResourceSet.

Within Acceleo, you use an extended Classic OCL which again could work provided you are using the correct ResourceSet.

For AQL you should ask on the Sirius newsgroup.

Regards

Hello Ed,

thank you for your answer. Sorry for posting in the wrong newsgroup. I thought those AQL topics are related to this one.

Best regards
Nico
