receive_tupleT_receive_tupleReceiveTupleReceiveTuplereceive_tuple (Operator)
Name
receive_tupleT_receive_tupleReceiveTupleReceiveTuplereceive_tuple — Receive a tuple over a socket connection.
Signature
Herror T_receive_tuple(const Htuple Socket, Htuple* Tuple)
def receive_tuple(socket: HHandle) -> Union[float, int, str]
Description
receive_tuplereceive_tupleReceiveTupleReceiveTuplereceive_tuple reads a TupleTupleTupletupletuple that was sent over the socket
connection determined by SocketSocketSocketsocketsocket by another HALCON process
using the operator send_tuplesend_tupleSendTupleSendTuplesend_tuple.
If no tuple has been sent, the HALCON process calling receive_tuplereceive_tupleReceiveTupleReceiveTuplereceive_tuple
blocks until enough data arrives.
For a detailed example, see open_socket_acceptopen_socket_acceptOpenSocketAcceptOpenSocketAcceptopen_socket_accept.
Attention
receive_tuplereceive_tupleReceiveTupleReceiveTuplereceive_tuple does not allow receiving tuples containing
HALCON handles.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
