[Rcpp-devel] Locating an Instance of a Reference Class in the Environment

[Matthew Supernaw - NOAA Federal]

I'm trying to get an instance of a reference class
(vonBertalanffyInterface) from the R environment with the following code:

void SetName(vonBertalanffyInterface& v) {

    Rcpp::Environment env = Rcpp::Environment::global_env();
    Rcpp::List l = Rcpp::as<Rcpp::List>(env.ls(true));

    for (int i = 0; i < l.size(); i++) {
        std::cout << typeid (l[i]).name() << std::endl;

        if(&v == l[i].get()){
            v.name Rcpp::as<std::string>(l[i]);
        }
    }
}

The problem is that elements in the list are of type
*N4Rcpp8internal13generic_proxyILi19ENS_15PreserveStorageEEE*.

I'm assuming that PreserveStorage is a wrapper class. Is there a way to
retrieve the reference class from the PreserveStorage object?
Thanks.
Matthew
