Destructor implementation.
This method is called by Dispose() or by the Object's destructor, whichever comes first.
Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.
It is safe to call GetObject() from within this method.
Reimplemented from ns3::Object.
Reimplemented in ns3::PacketSocketClient, and ns3::PacketSocketServer.

Initialize() implementation.
This method is called only once by Initialize(). If the user calls Initialize() multiple times, DoInitialize() is called only the first time.
Subclasses are expected to override this method and chain up to their parent's implementation once they are done. It is safe to call GetObject() and AggregateObject() from within this method.

void ns3::Application::SetStartTime | ( | Time | start | ) |
Specify application start time.
start | Start time for this application, relative to the current simulation time. |
Applications start at various times in the simulation scenario. This method specifies when the application should be started. The application subclasses should override the private "StartApplication" method defined below, which is called at the time specified, to cause the application to begin.

References m_startTime, and NS_LOG_FUNCTION.
void ns3::Application::SetStopTime | ( | Time | stop | ) |
Specify application stop time.
stop | Stop time for this application, relative to the current simulation time. |
Once an application has started, it is sometimes useful to stop the application. This method specifies when an application is to stop. The application subclasses should override the private StopApplication method, to be notified when that time has come.
