/* This file defines an internal function for processing default arguments
with proxy classes.
There seems to be no straightforward way to write proxy functions
involving default arguments. For example :
def foo(arg1,arg2,*args):,arg2,args)
This fails because args is now a tuple and SWIG doesn't know what to
do with it.
This file allows a different approach :
def foo(arg1,arg2,*args):
Basically, we form a new tuple from the object, call this special
__call_defarg method and it passes control to the real wrapper function.
An ugly hack, but it works.
SWIGINTERN PyObject *swig_call_defargs(PyObject *self, PyObject *args) {
PyObject *func;
PyObject *parms;
if (!PyArg_ParseTuple(args,"OO",&func,&parms))
return NULL;
if (!PyCallable_Check(func)) {
PyErr_SetString(PyExc_TypeError, "__call_defarg : Need a callable object!");
return NULL;
return PyEval_CallObject(func,parms);
