Hi,
I'm working with a C++ module ( CGAL, comp.geom. with exact arithmic )
and am having troubles finding a way to override how the modules returns
objects. What I'm trying to do is to extend the Facet class, but when I try
to use my version of the class, the parent class is still being returned
import CGAL
CGAL.Facet = OtherFacet
CGAL.Polyhedron.Facet = OtherFacet
p = CGAL.Polyhedron_3()
You're not creating Facet object here, not even Polyhedron.Facet.
p.make_triangle()
for f in p.facets:
print f
<CGAL.Polyhedron.Facet object at 0x47ed50>
# Here I was expecting a OtherFacet object
Is there a way of getting around this, or is this behaviour hardcoded in the
C++ module?
I think so. External module written in C/C++ is often statically linked.
Can I perhaps alter it using the new module or __new__ method?
Many thanks in advance,
