Yes, but it seems I'm unable to see the wood for the trees.
The concrete situation:
Im developing a Interface that supposedly is going to enable AIs being written in Python for a C/C++ environment. What I get is a pointer to a Callback Instance I have to deliver to the AI dev (Python side). The Instance enables the AI dev to ask question about the Applications state so the AI reacts accordingly. Now I have a boost::module wrapper for the Class Im getting a reference of and successfully built a callback so the embedded Python is able to fetch the Callback Instance coming from the App. But I run into...
Sandbox:
// The Callback coming from the Application of which I am not allowed to taint the Source Tree
struct EngineCallback
{
void setInt(int number) { this->number = number; }
void setLoop(bool loop) { this->loop = loop; }
int getInt() { return this->number; }
bool getLoop() { return this->loop; }
int number;
bool loop;
};
EngineCallback* test = new EngineCallback;
// Entrypoint for Python to come ant fetch the Application Callback
shared_ptr<EngineCallback> PyCallback( EngineCallback* &test ) { return shared_ptr<EngineCallback>(test); } // The Problem? ...how to convert?
// The Wrapper for all this
BOOST_PYTHON_MODULE(EngineCallback)
{
class_<EngineCallback, shared_ptr<EngineCallback>, boost::noncopyable>("EngineCallback", no_init)
.def("setInt", &EngineCallback::setInt)
.def("setLoop", &EngineCallback::setLoop)
.def("getInt", &EngineCallback::getInt)
.def("getLoop", &EngineCallback::getLoop)
;
def("PyCallback", &PyCallback);
}
# test.py
from EngineCallback import PyCallback
from EngineCallback import EngineCallback
test = PyCallback()
dir(test)
>>>>>> ends in:
Traceback (most recent call last):
File "test.py", line 5, in <module>
test = PyCallback()
Boost.Python.ArgumentError: Python argument types in
EngineCallback.PyCallback()
did not match C++ signature:
PyCallback(EngineCallback* {lvalue})
Conversions in PyCallback missing?, how/with what do I accomplish them?
I think Im having trouble with C/C++ more in general than anything else, but I would appreciate if you could just point to the things I should look at to understand and come up with a solution.
Thanks in advance,
