Hi

I am using xcore for my meta-model, and am trying to use acceleo to generate classes.

Below is my acceleo template.

Here is a snippet from my xcore model:

class Role{
	String name
}

My current acceleo template- which is obviously incorrect - is generating:

public class Role{

	private org.eclipse.emf.ecore.xcore.XAttribute name;
     public Name getName getName() {
       return this.name;
}

How can I do find the type - in this case String - in the acceleo template?

[template public generateElement(aXClass : XClass)]
[comment @main/]
[file (aXClass.name.concat('.java'), false, 'UTF-8')]
public class [aXClass.name.toUpperFirst()/]{

[for (m: XMember | aXClass.members) separator('\n')]
	private [m.type.eContainer().eClass().instanceTypeName /] [m.name.toLowerCase()/];
[/for]
[for (p: XMember | aXClass.members) separator('\n')]
     public [p.name.toString().toUpperFirst() /] get[p.name.toUpperFirst()/] get[p.name.toUpperFirst()/]() {
       return this.[p.name/];
     }
[/for]
[for (o: XOperation | aXClass.) separator('\n')]
     public [o.type.name/] [o.name/]() {
       // TODO should be implemented
     }

Hi

Since no one who understands Xcore is answering....

Doing a transformation on Xcore types seems really wierd since you shut
yourself off from many other modeling technologies. Convert the Xcore to
Ecore and transform that. There are many examples of transformations on
Ecopre.
