Dotan, in
barPolicy = GetBarWithPolic(Io) barPolicy = GetBarWithPolic(File) what type of object would you imaginge `Io` and `File` to be?
You already exported the functions as `GetBarWithPolicIo` and `GetBarWithPolicFile` and then you could implement in python `GetBarWithPolic(str)` and there use something like `return globals()["GetBarWithPolic%s" % (str,)]()` where you would now do barPolicy = GetBarWithPolic("Io") barPolicy = GetBarWithPolic("File") -Holger On Sun, Mar 17, 2013 at 6:49 AM, dbarak <dbarak@gmail.com> wrote:
Assume I have this Interface: class FooInterface { public: ...
};
class FooFilePolicy : public FooInterface { ... };
class FooIoPolicy : public FooInterface { ... };
And I have this template using the upper interface policy:
template< typename FooPolicy > class BarWithPolicy { ... FooPolicy* policy; ... };
How can I expose BarWithPolicy to python that can be generically instantiate with both FooIoPolicy and FooFilePolicy ?
I don't want to do this :
BarWithPolicy<FooFilePolicy >& GetBarWithPolicyFile() { return new BarWithPolicy<FooFilePolicy >; }
BarWithPolicy<FooIoPolicy>& GetBarWithPolicyIo() { return new BarWithPolicy<FooIoPolicy >; }
BOOST_PYTHON_MODULE(PyBar) { def("GetBarWithPolicyFile", &GetBarWithPolicyFile, return_value_policy<reference_existing_object>(), "" ); def("GetBarWithPolicyIo", &GetBarWithPolicyIo, return_value_policy<reference_existing_object>(), "" ); }
I would like to have some thing like this in python:
barPolicy = GetBarWithPolic(Io) Or barPolicy = GetBarWithPolic(File)
Thanks -Dotan
