Constructor & Destructor Documentation

◆ TestParentQueueDisc()

TestParentQueueDisc::TestParentQueueDisc ( )

Constructor.

Member Function Documentation

◆ CheckConfig()

bool TestParentQueueDisc::CheckConfig ( void  )
virtual

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.

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

Implements ns3::QueueDisc.

+ Here is the call graph for this function:

◆ DoDequeue()

Ptr< QueueDiscItem > TestParentQueueDisc::DoDequeue ( void  )
virtual

This function actually extracts a packet from the queue disc.

Returns
0 if the operation was not successful; the item otherwise.

Implements ns3::QueueDisc.

References ns3::QueueDisc::GetQueueDiscClass().

+ Here is the call graph for this function:

◆ DoEnqueue()

bool TestParentQueueDisc::DoEnqueue ( Ptr< QueueDiscItem item)
virtual

This function actually enqueues a packet into the queue disc.

Parameters
itemitem to enqueue
Returns
True if the operation was successful; false otherwise

Implements ns3::QueueDisc.

References ns3::QueueDisc::GetQueueDiscClass().

+ Here is the call graph for this function:

◆ InitializeParams()

void TestParentQueueDisc::InitializeParams ( void  )
virtual

Initialize parameters (if any) before the first packet is enqueued.

This method is automatically called at simulation initialization time, after the CheckConfig() method has been called.
