[acceleo] how to return a List (or array or whatever) from an query [message #727263]

Hi

is it possible to return a list of elements from a query statement?

[query public xxx(aYYY:YYY) : Sequence
= invoke('myClassThatReturnsAList',
'xxx(YYY)', Sequence{aYYY}) /]

if I have something like

public List xxx(yyy){
return new ArrayList();
}

?

I am sorry asking this, sounds like a stupid question, but in the MOF M2T document, section 8.2, the BNF of the language syntax describes the return type of a query as a <typeCS>, where typeCS isn´t described anywhere I could find Sad

TIA

Kenji

Hi Kenji,

You did figure this out, but for future reference, the examples and help we ship along with Acceleo might be better sources of answers for such questions Smile
