/* This file defines an internal function for processing default arguments
|
|
with shadow classes.
|
|
|
|
There seems to be no straightforward way to write a shadow functions
|
|
involving default arguments. For example :
|
|
|
|
def foo(arg1,arg2,*args):
|
|
shadowc.foo(arg1,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):
|
|
shadowc.__call_defarg(shadowc.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.
