Exiting an Active State

A state is exited (becomes inactive) in one of the following ways:

• Its boundary is the origin of an outgoing executed transition.
• Its boundary is crossed by an outgoing executed transition.
• It is a parallel state child of an activated state.

A state performs its exit action (if specified) before it becomes inactive. The state is marked inactive after the exit action has executed and completed.

The execution steps for exiting a state are as follows:

1. If this is a parallel state, and one of its sibling states was entered before this state, exit the siblings starting with the last-entered and progressing in reverse order to the first-entered. See step 2 of Entering a State.
2. If there are any active children, perform the exit steps on these states in the reverse order they were entered.
3. Perform any exit actions.
4. Mark the state as inactive.
