Detailed Description

template<typename T>
class ns3::SimulationSingleton< T >

This singleton class template ensures that the type for which we want a singleton has a lifetime bounded by the simulation run lifetime.

That it, the underlying type will be automatically deleted upon a call to Simulator::Destroy.

For a singleton with a lifetime bounded by the process, not the simulation run, see Singleton.

◆ SimulationSingleton() [1/2]

template<typename T >
ns3::SimulationSingleton< T >::SimulationSingleton ( )

Member Function Documentation

◆ DeleteObject()

template<typename T >
void ns3::SimulationSingleton< T >::DeleteObject
staticprivate

Delete the static instance.

Definition at line 111 of file simulation-singleton.h.

◆ Get()

◆ GetObject()

template<typename T >
T ** ns3::SimulationSingleton< T >::GetObject
staticprivate

Get the singleton object, creating a new one if it doesn't exist yet.

Internal:
When a new object is created, this method schedules it's own destruction using Simulator::ScheduleDestroy().
Returns
The address of the pointer holding the static instance.
