## Detailed Description

Holds a vector of ns3::QueueDisc pointers.

Typically ns-3 QueueDiscs are installed on net devices using a traffic control helper. The helper Install method takes a NetDeviceContainer which holds some number of Ptr<NetDevice>. For each of the net devices in the NetDeviceContainer the helper will instantiate a queue disc and install it to the net device. For each of the queue discs, the helper also adds the queue disc into a Container for later use by the caller. This is that container used to hold the Ptr<QueueDisc> which are instantiated by the traffic control helper.

Here is the caller graph for this function:

 void ns3::QueueDiscContainer::Add ( Ptr< QueueDisc > qDisc )

Append a single Ptr<QueueDisc> to this container.

Parameters
 qDisc The Ptr to append.

 QueueDiscContainer::ConstIterator ns3::QueueDiscContainer::Begin ( void ) const

Get a const iterator which refers to the first QueueDisc in the container.

QueueDiscs can be retrieved from the container in two ways. First, directly by an index into the container, and second, using an iterator. This method is used in the iterator method and is typically used in a for-loop to run through the QueueDiscs

for (i = container.Begin (); i != container.End (); ++i)
{
(*i)->method (); // some QueueDisc method
}
Returns
a const iterator which refers to the first QueueDisc in the container.

Here is the caller graph for this function:

 QueueDiscContainer::ConstIterator ns3::QueueDiscContainer::End ( void ) const

Get a const iterator which indicates past-the-last QueueDisc in the container.

QueueDiscs can be retrieved from the container in two ways. First, directly by an index into the container, and second, using an iterator. This method is used in the iterator method and is typically used in a for-loop to run through the QueueDiscs

for (i = container.Begin (); i != container.End (); ++i)
{
(*i)->method (); // some QueueDisc method
}
Returns
a const iterator which indicates an ending condition for a loop.

Here is the caller graph for this function:

 Ptr< QueueDisc > ns3::QueueDiscContainer::Get ( std::size_t i ) const

Get the Ptr<QueueDisc> stored in this container at a given index.

QueueDiscs can be retrieved from the container in two ways. First, directly by an index into the container, and second, using an iterator. This method is used in the direct method and is used to retrieve the indexed Ptr<QueueDisc>.

uint32_t nQueueDiscs = container.GetN ();
for (uint32_t i = 0 i < nQueueDiscs; ++i)
{
Ptr<QueueDisc> p = container.Get (i)
i->method (); // some QueueDisc method
}
Parameters
 i the index of the requested queue disc pointer.
Returns
the requested queue disc pointer.

Here is the caller graph for this function:

 std::size_t ns3::QueueDiscContainer::GetN ( void ) const

Get the number of Ptr<QueueDisc> stored in this container.

QueueDiscs can be retrieved from the container in two ways. First, directly by an index into the container, and second, using an iterator. This method is used in the direct method and is typically used to define an ending condition in a for-loop that runs through the stored QueueDiscs

uint32_t nQueueDiscs = container.GetN ();
for (uint32_t i = 0 i < nQueueDiscs; ++i)
{
Ptr<QueueDisc> p = container.Get (i)
i->method (); // some QueueDisc method
}
Returns
the number of Ptr<QueueDisc> stored in this container.
