描述

receive_serialized_itemreceive_serialized_itemReceiveSerializedItemReceiveSerializedItemReceiveSerializedItemreceive_serialized_item 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_itemSendSerializedItemSendSerializedItemSendSerializedItemsend_serialized_item (see fwrite_serialized_itemfwrite_serialized_itemFwriteSerializedItemFwriteSerializedItemFwriteSerializedItemfwrite_serialized_item for an introduction of the basics of serialization). If no serialized item has been sent, the HALCON process calling receive_serialized_itemreceive_serialized_itemReceiveSerializedItemReceiveSerializedItemReceiveSerializedItemreceive_serialized_item 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 SerializedItemHandleSerializedItemHandleSerializedItemHandleSerializedItemHandleserializedItemHandleserialized_item_handle. For a detailed example showing the use of a socket connection, see open_socket_acceptopen_socket_acceptOpenSocketAcceptOpenSocketAcceptOpenSocketAcceptopen_socket_accept。

执行信息

• 多线程类型：可重入（与非独占算子并行运行）。
• 多线程作用域：全局（可从任何线程调用）。
• 未采用并行化处理。
