A raised event is a type of generated event that is explicitly mentioned in the statechart. A raised event is usually declared as an action assigned to the entry or exit of a state, or on a transition between states.
A raised event is usually shown in the same manner as actions, in other words, after a slash. For example
entry / B, which would mean that if this state was entered, the system would generate the event
B and process it as part of the current event, before processing any external events.
