R help - Jun 2011 - Rcpp and Object Factories

Hello,
I'm not exactly sure how to ask this question, but let me give it a shot...

Is it possible (easy) to use Rcpp Modules in conjunction with object
factories? For example

what I am trying to do is something like this:

// c++ classes

class Foo {
  public:
    void do_something() {};
};

class Foo_Factory {
  public:
    Foo * create_foo() {
      return new Foo();
   }
};

## R Code

library(Rcpp)
ff <- Module("Foo_Factory")
foo <- ff$create_foo()
foo$do_something()

It appears after scouring some message boards that it is doable via boost
python, but i'm not literate enough yet about how this works to know if the
same logic holds for R.

Thanks for the help.

You might want to send this message to the Rcpp mailing list at:
Rcpp-devel mailing list
Rcpp-devel at lists.r-forge.r-project.org
https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel

It will improve your chances of getting a swift (if not helpful) reply.
