I want to generate a class with the jvmInverrer which has a generic type parameter.
How could I do that ?

hi i have no idea if this is a supported usecase but at least in very simple cases it seems to work

TypesFactory.eINSTANCE.createJvmTypeParameter => [
				name = "T"
			]
accept(entity.toClass( entity.fullyQualifiedName )) [
			typeParameters += t
			documentation = entity.documentation
			if (entity.superType != null)
				superTypes += entity.superType.cloneWithProxies
			
			// let's add a default constructor
			members += entity.toConstructor []
			
			members += entity.toMethod("doWithT", t.typeRef) [
				parameters += entity.toParameter("t", t.typeRef) 
				body = '''return null;'''
			]
......
