Set the cancel bit on this event: the event's associated function will not be invoked when it expires.
This method has the same visible effect as the ns3::Simulator::Remove method but its algorithmic complexity is much lower: it has O(1) complexity. This method has the exact same semantics as ns3::EventId::Cancel. Note that it is not possible to cancel events which were scheduled for the "destroy" time. Doing so will result in a program error (crash).

overridevirtual |
Execute the events scheduled with ScheduleDestroy().
This method is typically invoked at the end of a simulation to avoid false-positive reports by a leak checker. After this method has been invoked, it is actually possible to restart a new simulation with a set of calls to Simulator::Run, Simulator::Schedule and Simulator::ScheduleWithContext.

Get the current simulation context.
The simulation context is the ns-3 notion of a Logical Process. Events in a single context should only modify state associated with that context. Events for objects in other contexts should be scheduled with ScheduleWithContext() to track the context switches. In other words, events in different contexts should be mutually thread safe, by not modify overlapping model state.
In circumstances where the context can't be determined, such as during object initialization, the enum
value NO_CONTEXT
should be used.

Check if an event has already run or been cancelled.
This method has O(1) complexity. Note that it is not possible to test for the expiration of events which were scheduled for the "destroy" time. Doing so will result in a program error (crash). An event is said to "expire" when it starts being scheduled which means that if the code executed by the event calls this function, it will get true.
