It is recommended to create your own semantically meaningful message. However if you would like to continue using this please use the equivalent in example_msgs.

Please look at the MultiArrayLayout message definition for documentation on all multiarrays.

Int32MultiArrayPublisher publishes int32MultiArray values to a ROS 2 topic. Set the topic and node properties, then call publish() to send messages.
