Hey all,

I've one question!
I'm trying to count the amount of abstract classes from one EPackage using
ATL. (ECore)

If I execute the following command line in Interactive OCL, it works:
self.eClassifiers->select(c|c.oclIsTypeOf(EClass)).oclAsType(EClass)- >select(d|
d.abstract = true)->size()

The following code, is the implementation in ATL!

helper context Source!EPackage def: getQtAbstractClasses : Integer =

self.eClassifiers-> select(c|c.oclIsTypeOf(Source!EClass)).oclAsType(Source!ECla ss)- >select(d|
d.abstract = true)->size();

P.S.: Source = ECORE

This implementation is not working, the error msg is shown bellow:

SEVERE: ****** BEGIN Stack Trace
SEVERE: message: ERROR: could not find operation oclAsType on

Could some one help me? Or maybe tell me where I can get more information
about it? 8)

Thanks in advance,

Hi,

According to the doc
(http://wiki.eclipse.org/ATL/User_Guide#OclAny_operations), oclAsType
isn't implemented in ATL.

Here is a previous question similar to yours:
http://dev.eclipse.org/mhonarc/newsLists/news.eclipse.modeli ng.m2m/msg01963.html

In your case, as you previously did a "select", I think the "oclAsType"
is not mandatory.

Best regards,

William
