[news.eclipse.modeling.m2m] [ATL] generating ECore!EString or ECore!EInt

[Olivier PATRY <olivier.patry@xxxxxxxxxxxxxxxxxx>]

Hello,

I'm trying to transform a model conform to a personal metamodel to ECore.

In my metamodel, I had an enumeration PrimitiveType with literals 
String, Integer, Boolean, Float

I want to transform these personnal types into corresponding ECore types.

I try with
eType <- ECore!EString

wich works well, but I didn't know how to test the "source" type to 
choose the ECore type (ECore!EString, ECore!EInt, ...)

I try with an helper or lazy rule like

helper context MM!PrimitiveType def : getEType : ECore!???? =
	if String then ECore!EString
	else ...
;

lazy rule getEType
{
	from type :MM!PrimitiveType
	to etype: ECore!????(
	??? <- EString -- how to choose the right type ?
	)
}

How can I do that, and what is the type of ECore!EString or ECore!EInt ?

Thank you.

(if there is a better way to make the correspondance between ECore 
primitive types (all) and personnal PrimitiveType, I'm interested ;) )

Bye.
