Instance Method Details

#timestamp_accessor(event, accessor) ⇒ Object

Register the timestamp access for an event. A timestamp accessor reads when a certain transition happened by looking at the timestamp of the successful transition into that state.

The event can be just the event name, or a hash of <event method symbol>, from: <state name>, used when a single event can cause multiple transitions.
