Re: [Rcpp-devel] Not able to convert from Rcpp::NumericVector to Teuchos::ArrayRCP
Hello,
From what I understand of ArrayRCP, having read the documentation for a few
minutes.
(http://trilinos.sandia.gov/packages/docs/r9.0/packages/teuchos/doc/html/classTeuchos_1_1ArrayRCP.html)
This looks like a vector and therefore it is likely that the default
Exporter will not be useful as it tries to use the constructor taking a SEXP
:
template
class Exporter{
public:
Exporter( SEXP x ) : t(x){}
inline T get(){ return t ; }
private:
T t ;
} ;
you can use a RangeExporter instead which looks more compatible to what
ArrayRCP looks like:
template class RangeExporter {
public:
typedef typename T::value_type r_export_type ;
RangeExporter( SEXP x ) : object(x){}
~RangeExporter(){}
T get(){
T vec( ::Rf_length(object) );
::Rcpp::internal::export_range( object, vec.begin() ) ;
return vec ;
}
private:
SEXP object ;
} ;
You can probably do this by having something like this early enough (after
RcppCommon.h but before Rcpp.h).
namespace Rcpp {
namespace traits {
template class Exporter< Teuchos::ArrayRCP > : public
RangeExporter< Teuchos::ArrayRCP >{
public:
Exporter( SEXP x) : RangeExporter< Teuchos::ArrayRCP >(x){}
}
}
}
