[XPAND] [XTEND] hot to get the number of parameters for an operation [message #504715]

hello to all,

I want to get the number of parameters of an operation to generate Java code out of UML
I need only the number of parameters to insert it inside an array.
I have something like the following.. I do not know what to insert inside the FOREACH block instead of the question marks.

«FOREACH trueParameters() AS p ITERATOR i-»
?????????????????????????
«ENDFOREACH»

thanx in-advance

I'm assuming that you mean parameters for an uml::Operation...

«FOREACH ownedParameters.reject(e|e.direction!=uml::ParameterDirectionKind::return) AS p ITERATOR i-»
«ENDFOREACH»

the following has worked
xtend

int count (uml::Operation o) : o.ownedParameter.size;

and call it in your template like this

«count()-1»
