receive_tupleT_receive_tupleReceiveTupleReceiveTuplereceive_tuple (Operator)
Name
receive_tupleT_receive_tupleReceiveTupleReceiveTuplereceive_tuple — Empfangen eines Tupels über eine Socket-Verbindung.
Signatur
Herror T_receive_tuple(const Htuple Socket, Htuple* Tuple)
def receive_tuple(socket: HHandle) -> Union[float, int, str]
Beschreibung
receive_tuplereceive_tupleReceiveTupleReceiveTupleReceiveTuplereceive_tuple liest das in TupleTupleTupleTupletupletuple gegebene Tupel,
welches von einem anderen HALCON-Prozess über die Socket-Verbindung
SocketSocketSocketSocketsocketsocket mit dem Operator send_tuplesend_tupleSendTupleSendTupleSendTuplesend_tuple geschickt worden ist.
Wenn noch kein Tupel verschickt worden ist, wird der Prozess, der
receive_tuplereceive_tupleReceiveTupleReceiveTupleReceiveTuplereceive_tuple aufgerufen hat, blockiert, bis genug Daten
eingetroffen sind.
Für ein ausführliches Beispiel siehe open_socket_acceptopen_socket_acceptOpenSocketAcceptOpenSocketAcceptOpenSocketAcceptopen_socket_accept.
Achtung
receive_tuplereceive_tupleReceiveTupleReceiveTupleReceiveTuplereceive_tuple verbietet das Einlesen von Tupeln mit HALCON Handles.
Ausführungsinformationen
- Multithreading-Typ: reentrant (läuft parallel zu nicht-exklusiven Operatoren).
- Multithreading-Bereich: global (kann von jedem Thread aufgerufen werden).
- Wird ohne Parallelisierung verarbeitet.
