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.

Constructor & Destructor Documentation

◆ SimulationSingleton() [1/2]

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

Default constructor.

◆ SimulationSingleton() [2/2]

template<typename T>
ns3::SimulationSingleton< T >::SimulationSingleton ( const SimulationSingleton< T > &  )
private

Copy constructor.

Member Function Documentation

◆ DeleteObject()

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

Delete the static instance.

Definition at line 128 of file simulation-singleton.h.

◆ Get()

◆ GetObject()

template<typename T >
T ** ns3::SimulationSingleton< T >::GetObject ( void  )
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.

+ Here is the call graph for this function:

◆ operator=()

template<typename T>
SimulationSingleton<T> ns3::SimulationSingleton< T >::operator= ( const SimulationSingleton< T > &  )

Assignment.

Returns
The Singleton.
