[news.eclipse.modeling.m2t] Re: How to exit the FOR LOOP

[laurent Goubet <laurent.goubet@xxxxxxx>]

Hi Omran,

There is no such functionality in either Acceleo or OCL. However what 
you seek seems like the "exists" collection iterator to me (and yes, 
"exists" does shortcut the evaluation if an element fulfills the condition).

----------8<----------
[if (mv.columns->select(oclIsTypeOf(ViewExpColumn))->exists(let exp : 
String = expression.trim().toUpper() in exp.startsWith('SUM') or 
exp.startsWith('AVG') or exp.startsWith('MIN') or exp.startsWith('MAX') 
or exp.startsWith('COUNT')))]
GROUP BY
[/if]
---------->8----------
