The Timer and Watchdog objects both facilitate scheduling functions to execute a specified virtual time in the future.
A Watchdog timer cannot be paused or cancelled once it has been started, however it can be lengthened (delayed). A Watchdog takes no action when it is destroyed.
A Timer can be suspended, resumed, cancelled and queried for time left, but it can't be extended (except by suspending and resuming). In addition, it can be configured to take different actions when the Timer is destroyed.
The policy to use to manager the internal timer when an instance of the Timer class is destroyed.
Enumerator | |
---|---|
CANCEL_ON_DESTROY |
This policy cancels the event from the destructor of the Timer to verify that the event has already expired. |
REMOVE_ON_DESTROY |
This policy removes the event from the simulation event list when the destructor of the Timer is invoked. |
CHECK_ON_DESTROY |
This policy enforces a check from the destructor of the Timer to verify that the timer has already expired. |
