Name

receive_serialized_itemreceive_serialized_itemReceiveSerializedItemreceive_serialized_itemReceiveSerializedItemReceiveSerializedItem — Receive a serialized item over a socket connection.

Signature

Description

receive_serialized_itemreceive_serialized_itemReceiveSerializedItemreceive_serialized_itemReceiveSerializedItemReceiveSerializedItem receives a serialized item that was sent over the socket connection determined by SocketSocketSocketSocketSocketsocket of another HALCON process using the operator send_serialized_itemsend_serialized_itemSendSerializedItemsend_serialized_itemSendSerializedItemSendSerializedItem (see fwrite_serialized_itemfwrite_serialized_itemFwriteSerializedItemfwrite_serialized_itemFwriteSerializedItemFwriteSerializedItem for an introduction of the basics of serialization). If no serialized item has been sent, the HALCON process calling receive_serialized_itemreceive_serialized_itemReceiveSerializedItemreceive_serialized_itemReceiveSerializedItemReceiveSerializedItem blocks until enough data arrives. The data is stored in a new created serialized item. The operator returns the handle of the serialized item in parameter SerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandle. For a detailed example showing the use of a socket connection, see open_socket_acceptopen_socket_acceptOpenSocketAcceptopen_socket_acceptOpenSocketAcceptOpenSocketAccept.

Parallelization

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.

Parameters

Result

If the parameters are valid, the operator receive_serialized_itemreceive_serialized_itemReceiveSerializedItemreceive_serialized_itemReceiveSerializedItemReceiveSerializedItem returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.
