void ns3::UeManager::DoDispose ( void )

protectedvirtual

This method is called by Object::Dispose or by the object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overriden 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.

void ns3::UeManager::DoInitialize ( void )

protectedvirtual

This method is called only once by Object::Initialize.

If the user calls Object::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.
