/*

|
Use the "nondynamic" feature to make a wrapped class behaves as a "nondynamic"
|
|
one, ie, a python class that doesn't dynamically add new attributes.
|
|
|
|
For example, for the class
|
|
|
|
%pythonnondynamic(1) A;
|
|
struct A
|
|
{
|
|
int a;
|
|
int b;
|
|
};
|
|
|
|
you will get:
|
|
|
|
aa = A()
|
|
aa.a = 1 # Ok
|
|
aa.b = 1 # Ok
|
|
aa.c = 3 # error
|
|
|
|
Since "nondynamic" is a feature, if you use it like
|
|
|
|
%pythonnondynamic(1);
|
|
|
|
it will make all the wrapped classes nondynamic ones.
|
|
|
|
The implementation is based on the recipe:
|
|
|
|
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/252158
|
|
|
|
and works for modern (-modern) and plain python. We don't use __slots__,
|
|
so, it works with old python versions.
|
|
|
|
You can also use the raw %feature form
|
|
|
|
%feature("pythonnondynamic") A;
|
|
|
|
or the inverse form
|
|
|
|
%pythondynamic(0) A;
|
|
|
