XMLRPC Server xmlrpc_server import SimpleXMLRPCServer import threading SimpleXMLRPCServer.SimpleXMLRPCServer(($addr, $port), allow_none=True) self.$(id).register_instance(self) threading.Thread(target=self.$(id).serve_forever).start() Address addr localhost string Port port 8080 int This block will start an XMLRPC server. \ The server provides access to the run, start, stop, wait functions of the flow graph. \ The server also provides access to the variable callbacks in the flow graph. \ Ex: If the variable is called freq, the function provided by the server will be called set_freq(new_freq). Example client in python: import xmlrpclib s = xmlrpclib.Server("http://localhost:8080") s.set_freq(5000)
