Detailed Description

A simulation event.

Each subclass of this base class represents a simulation event. The Invoke() method will be called by the simulation engine when it reaches the time associated to this event. Most subclasses are usually created by one of the many Simulator::Schedule methods.

Member Function Documentation

Cancel()

void ns3::EventImpl::Cancel

(

)

Marks the event as 'canceled'.

The event is not removed from the event list but the simulation engine will check its canceled status before calling Invoke().

Invoke()

void ns3::EventImpl::Invoke

(

Implementation for Invoke().

This typically calls a method or function pointer with the arguments bound by a call to one of the MakeEvent() functions.
