Member Function Documentation

◆ CheckConfig()

bool ns3::FqCobaltQueueDisc::CheckConfig ( void  )
privatevirtual

Check whether the current configuration is correct.

Default objects (such as internal queues) might be created by this method to ensure the configuration is correct. This method is automatically called at simulation initialization time, and it is called before the InitializeParams () method. It is appropriate to promote parameter initialization to this method if it aids in checking for correct configuration.

QueueDisc::InitializeParams
Returns
true if the configuration is correct, false otherwise
