[Swig-user] typemaps for template

[david r. m. <dav...@gm...>]

Hi.

I have a new problem whit my code swig whit ypemaps and templates.
I need your experence because all my project is equal.

My problem.

/**********************example .h*****************************/

using namespace std;

#include <iostream>
#include <fstream>
#include <complex>
#include <cstdlib>
#include <cstdio>
#include <string>

void RealImag2Complex(const int _real,
const int _imag,
complex< double >* _complex,
int length)
{
int aux_real = (int) _real;
int aux_imag = (int) _imag;
std::cout<<*_complex<<std::endl;
}

/*****************my swigexample .i*************************/

%module swigexample
%include cpointer.i
%include std_complex.i
%pointer_class(double,doubleP);

%{

#include "swigexample.h"
#include <complex>

%}



%typemap(python,in) complex <double> *
{
if (!PyList_Check($input))
{
PyErr_SetString(PyExc_TypeError, "expected a list");
return NULL;
};

int arrsize = PyList_Size($input);

$1 = new complex <double> [arrsize];
for (int i=0; i<arrsize; i++)
{
PyObject *item = PyList_GetItem($input, i);
if (PyComplex_Check(item))
$1[i] = complex <double>(PyComplex_RealAsDouble(item),
PyComplex_ImagAsDouble(item));
else
{
free ((complex <double> *) $input);
PyErr_SetString(PyExc_TypeError, "expected complex numbers in list");
return NULL;
};

}

}

%typemap (python,freearg) complex <double> *
{
delete [] $1;
};

%typemap (python,out) complex<double> *{

$result = PyInt_FromLong($1);
}


%include "swigexample.h"



Please I need to konw the solution for the excepted a pointer

>>> z=complex(1+1j)
>>> swigfuncs.RealImag2Complex(2,2,z,3)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
TypeError: No matching function for overloaded 'RealImag2Complex'

It is possible to solve it or if you have a other solution, I accept all
solutions.

Thanks for your time and sorry for my English .
