Recently I used cython in my project and I came with idea that
sometimes virtual methods are overkill.
What's about adding non-virtual decorator for c[p]def methods?
cdef class Foo:
@cython.nonvirtual
cpdef int is_active(self):
return clib.obj_is_active(self._cobj)
How does that differ from the "final" decorator?
I tried final classes:
1. Final decorator doesn't work at pxd level (compiler crash)
Sounds like a bug.
2. In this example foo call is done through virtual table
cimport cython
@cython.final
cdef class Foo:
cdef foo(self):
print 'haha'
def test():
cdef Foo a = Foo()
a.foo()
__pyx_t_1 = ((struct __pyx_vtabstruct_3yyy_Foo
*)__pyx_v_a->__pyx_vtab)->foo(__pyx_v_a); if (unlikely(!__pyx_t_1))
{__pyx_filename = __pyx_f[0]; __pyx_lineno = 12; __pyx_clineno =
__LINE__; goto __pyx_L1_error;}
Right, this is not implemented yet. Feel free to do so. Also see
http://trac.cython.org/cython_trac/ticket/474
3. I can't use final decorator for methods (error reported)
