Le 22/11/10 19:48, Romain Francois a ?crit :
Done. Silly example updated ;


require( Rcpp )
require( inline )
inc <- '

class Simple {
public:
     Simple( ) : d_x(10.0){} ;
     Simple( double x ) : d_x(x){} ;

     const double& x(){ return d_x ;}

     void move( double x ) { d_x += x ; }
     double blabla() const { return d_x * 2 ; }

private:
     double d_x ;
		
} ;

double bla( Simple* data ){ return 3; }

RCPP_MODULE(mod){

	class_<Simple>( "Simple" )

	    .constructor( "default constructor" )
	    .constructor<double>( "bla bla bla" )
	
		.property( "x" , &Simple::x , "documentation for x" )
		.method( "move", &Simple::move, "some documentation for the move 
method" )
		.method( "blabla", &Simple::blabla, "some documentation for the blabla 
method" )
		.method( "bla", &bla, "bla bla" )
		;
		

}
'

fx <- cxxfunction( , '', includes = inc, plugin = "Rcpp" )
mod <- Module( "mod", getDynLib( fx ) )
Simple <- mod$Simple

 > show(Simple)
C++ class 'Simple' <0x1005450f0>
Constructors:
     Simple()
         docstring : default constructor
     Simple(double)
         docstring : bla bla bla

Fields:
     double x [readonly]
         docstring : documentation for x

Methods:
      double bla()
            docstring : bla bla
      double blabla()  const
            docstring : some documentation for the blabla method
      void move(double)
            docstring : some documentation for the move method


Anything else in that department ?
