import freetime.entity.msg as Msg msg = Msg.MsgPack() msg.setError("Something went wrong!") print(msg.error) # Output: Something went wrong!
import freetime.entity.msg as Msg class MyMessage(Msg.MsgPack): def __init__(self, value): self.value = value msg = MyMessage("Hello, World!") msg.setError("Error: Invalid message!") print(msg.error) # Output: Error: Invalid message!In this example, we create a custom message class `MyMessage` that inherits from `MsgPack`. We add a new attribute `value` to the class and set its value to "Hello, World!". We then set an error message using the `setError` method and print the error message to verify that it was set correctly. Overall, the `setError` method is a useful tool for setting error messages in Msg objects and helping to debug message processing.
