RE: [atl_discussion] UML2 transformation

Hello,

Yes, ->isEmpty() and ->notEmpty() should work if you have a recent ATL
version.

Yesterday afternoon, I started building an OCL tutorial
(work in progress) which is based on an OCL web test tool by Fred.
http://www.sciences.univ-nantes.fr/lina/atl/cgi-bin/atlwebservice.sh?query=t
rue+or+false
where you can test some OCL expressions that are supported by OCL.

Here is the link to the tutorial:
http://www.sciences.univ-nantes.fr/lina/atl/atldemo/oclturorial/

regards,
Peter

PS.: The version distributed on the GMT site and the version of the
OCL web test tool may not always be the same.
I have not checked if ->isEmpty() and ->notEmpty() is supported by the GMT
distributed version.

Another solution is to use ->isEmpty()

I was wondering if ->notEmpty() is supported ?
