Subscribing to Events

Subscribe statements are written using established Yantrix subsyntax. They have the following forms:

subscribe/<EVENT_NAME> <ACTION_NAME>
subscribe/<EVENT_NAME> <ACTION_NAME> (<PAYLOAD_KEY_LIST>)
subscribe/<EVENT_NAME> <ACTION_NAME> (<PAYLOAD_KEY_LIST>) <= (<META_KEY_LIST>)

In the generated code, each statement will be translated to the corresponding listener for the Event Adapter of the machine. It's important to remember that while Subscribe statements are written in notes attached to State nodes, subscription to events is not dependent on the current state of the automata. After catching some emitted event, Event Adapter will translate it to a corresponding Action that can be immediately dispatched to the automata.

Event naming follows the established standards for States and Actions.
