[Rcpp-devel] Extract names of functions in module

[Hola Kwame Adrakey]

Dear all,

Can anyone give me advice/help on how to list the name(s) of all functions
defined within a module?

Here is an example of what I am trying to achieve:

Assuming that I have

inc <- '
using namespace Rcpp;

double SE(double alpha, double beta, double epsilon){
return alpha;
};

double EI(double alpha, double beta, double epsilon){
return beta*alpha;
};

RCPP_MODULE(yada){
function( "SE", &SE,

List::create(
_["alpha"],
_["beta"],
_["epsilon"],
_["..."]));

function( "EI", &EI,

List::create(
_["alpha"],
_["beta"],
_["epsilon"],
_["..."]));

}

'
and

fx <- cxxfunction(signature(), plugin="Rcpp", include=inc)
mod <- Module("yada", getDynLib(fx)).

I can access say, the function SE by mod$SE. However, if the functions
defined within the module are not known (user defined for instance), I can
only access them by knowing their names.

I am currently using names(***@.xData$storage), but I have noticed that
there is a sort of randomness in its behavior, as, in some occasion, the
output is NULL.

Any help will be appreciated.

Best wishes,

We got your email yesterday. No need to repost.

I just don't have an answer for you. Adding reflexivity to C++ is not easy.
