	List<Operation> allOperations = EcoreUtil2.eAllOfType(resource.getContents().get(0), Operation.class);
	// get keyword for ')'
	Keyword rightParenthesisKeyword_4 = grammar.getOperationAccess().getRightParenthesisKeyword_4();
	for (Operation o : allOperations) {
		//inline annotations only for methods with no return type
		if (o.getType() != null) {

			}
		}
	}
}
