This macro should be invoked once for every required instance of a template class with one template parameter which derives from the Object class and defines a new GetTypeId method.

If the template class is in a namespace, then the macro call should also be in the namespace.

type	the template class
param	the first template parameter

Explicitly instantiate a template class with two template parameters and register the resulting instance with the TypeId system.

This macro should be invoked once for every required instance of a template class with two template parameters which derives from the Object class and defines a new GetTypeId method.

If the template class is in a namespace, then the macro call should also be in the namespace.

Template Parameters

type	the template class
param1	the first template parameter
param2	the second template parameter

◆ CreateObjectWithAttributes()

template<typename T , typename... Args>

Ptr< T > ns3::CreateObjectWithAttributes ( Args... args )
