描述
read_messageread_messageReadMessageReadMessageReadMessageread_message reads a message that has been stored with
write_messagewrite_messageWriteMessageWriteMessageWriteMessagewrite_message.
The default HALCON file extension for a message is 'hmsg'.
运行信息
- Multithreading type: independent (runs in parallel even with exclusive operators).
- 多线程作用域:全局(可以从任何线程调用)。
- 未经并行化处理。
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.
