You do not pass Socket instances to this, but rather Socket types:: Device(device_type, in_socket_type, out_socket_type) For instance:: dev = Device(zmq.QUEUE, zmq.DEALER, zmq.ROUTER) Similar to zmq.device, but socket types instead of sockets themselves are passed, and the sockets are created in the work thread, to avoid issues with thread safety. As a result, additional bind_{in|out} and connect_{in|out} methods and setsockopt_{in|out} allow users to specify connections for the sockets. Parameters ---------- device_type : int The 0MQ Device type {in|out}_type : int zmq socket types, to be passed later to context.socket(). e.g. zmq.PUB, zmq.SUB, zmq.REQ. If out_type is < 0, then in_socket is used for both in_socket and out_socket. Methods ------- bind_{in_out}(iface) passthrough for ``{in|out}_socket.bind(iface)``, to be called in the thread connect_{in_out}(iface) passthrough for ``{in|out}_socket.connect(iface)``, to be called in the thread setsockopt_{in_out}(opt,value) passthrough for ``{in|out}_socket.setsockopt(opt, value)``, to be called in the thread Attributes ---------- daemon : int sets whether the thread should be run as a daemon Default is true, because if it is false, the thread will not exit unless it is killed context_factory : callable (class attribute) Function for creating the Context. This will be Context.instance in ThreadDevices, and Context in ProcessDevices. The only reason it is not instance() in ProcessDevices is that there may be a stale Context instance already initialized, and the forked environment should *never* try to use it.
