I don't see that code as a wrapper. This is what I see in example.php
abstract class example {
static function CircleFactory($r_) {
$r=CircleFactory($r_);
return is_resource($r) ? new Circle($r) : $r;
}
}
the .i files is -
/* File : example.i */
%module example
%{
#include "example.h"
%}
/* Let's just grab the original header file here */
/*%newobject CircleFactory;*/
%include "example.h"
If I uncomment the %newobject line then I get no reference to the circle
factory at all.
I assume I am not putting something in the .i file that needs to be there.

Don't miss this year's exciting event. There's still time to save $100.
Use priority code J8TL2D2.
