A port is a communication endpoint that used by networking protocols, like TCP and UDP. To date, we only support TCP. This method may only be called before starting the server. Args: address: The address for which to open a port. If the port is 0, or not specified in the address, then the gRPC runtime will choose a port. Returns: An integer port on which the server will accept RPC requests. Nr)rrrrradd_insecure_port,szServer.add_insecure_port)rserver_credentialsrcCsdS)aLOpens a secure port for accepting RPCs. A port is a communication endpoint that used by networking protocols, like TCP and UDP. To date, we only support TCP. This method may only be called before starting the server. Args: address: The address for which to open a port. if the port is 0, or not specified in the address, then the gRPC runtime will choose a port. server_credentials: A ServerCredentials object. Returns: An integer port on which the server will accept RPC requests. Nr)rrrrrradd_secure_port=szServer.add_secure_portrcsdS)zgStarts this Server. This method may only be called once. (i.e. it is not idempotent). NrrrrrstartQsz Server.start)gracercsdS)aStops this Server. This method immediately stops the server from servicing new RPCs in all cases. If a grace period is specified, this method returns immediately and all RPCs active at the end of the grace period are aborted. If a grace period is not specified (by passing None for grace), all existing RPCs are aborted immediately and this method blocks until the last RPC handler terminates. This method is idempotent and may be called at any time. Passing a smaller grace value in a subsequent call will have the effect of stopping the Server sooner (passing None will have the effect of stopping the server immediately). Passing a larger grace value in a subsequent call will not have the effect of stopping the server later (i.e. the most restrictive grace value is used). Args: grace: A duration of time in seconds or None. Nr)rrrrrstopXsz Server.stop)timeoutrcsdS)aContinues current coroutine once the server stops. This is an EXPERIMENTAL API. The wait will not consume computational resources during blocking, and it will block until one of the two following conditions are met: 1) The server is stopped or terminated; 2) A timeout occurs if timeout is not `None`. The timeout argument works in the same way as `threading.Event.wait()`. https://docs.python.org/3/library/threading.html#threading.Event.wait Args: timeout: A floating point number specifying a timeout for the operation in seconds. Returns: A bool indicates if the operation times out.
