Dear All,

I have a for loop statement and under a specific condition I want to
"exit" or "break" or "quit" the loop.

Does this capability exist?
here is the code that I am working on

[for (vc:ViewColumn|mv.columns)]
[if (vc.oclIsTypeOf(ViewExpColumn))]
[let vec : ViewExpColumn = vc.oclAsType(ViewExpColumn)]
[if (vec.expression.trim().toUpper().startsWith('SUM') or
vec.expression.trim().toUpper().startsWith('AVG') or
vec.expression.trim().toUpper().startsWith('MAX') or
// I want here to exit the

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).

[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')))]
