[Swig-user] Need help with python typemap

[Edward M. <pap...@gm...>]

I have a class A that has been vectorized using std_vector.i. Once I
create a vector of A, I want to pass it to a method of class B.

My Python code looks like:

a = new ex.VA
b= new ex.B( "a", a, "unitY" )

And the exception that I get is:

Traceback (most recent call last):
  File "/Users/efm/tmp/sv/test.py", line 38, in <module>
    "unitY" )
  File "/Users/efm/build/SnowLeopard/sv/Example.py", line 399, in __init__
    this = _Example.new_B(*args)
NotImplementedError: Wrong number or type of arguments for overloaded
function 'new_B'.
  Possible C/C++ prototypes are:
    B::B(std::string const &,std::vector< Example::A,std::allocator<
Example::A > >,std::string const &)


I have wrapped the vectorization of A with:

class A
{
public
};

%include <std_vector.i>
namespace std {
  %template(VA) vector<A>;
}

class B
{
public:
  %extend {
    B( const std::string& Name,
        std::vector<A> As,
        const std::string& UnitY )
    {
      return new FrVect( Name,
             As.size( ),
             &(As[ 0 ]),
             UnitY );
    }
  } /* %extend */

}

Thanks for any insight,
Ed
