a polymophic address class
Definition: address.h:91
The packet header for an ARP packet.
Definition: arp-header.h:35
ArpQueueDiscItem is a subclass of QueueDiscItem which stores ARP packets.
virtual uint32_t Hash(uint32_t perturbation) const
Computes the hash of the packet's 5-tuple.
ArpHeader m_header
The ARP header.
bool m_headerAdded
True if the header has already been added to the packet.
virtual bool Mark(void)
Inherited from the base class, but we cannot mark ARP packets.
ArpQueueDiscItem & operator=(const ArpQueueDiscItem &)=delete
virtual ~ArpQueueDiscItem()
Destructor.
virtual void AddHeader(void)
Add the header to the packet.
ArpQueueDiscItem(const ArpQueueDiscItem &)=delete
const ArpHeader & GetHeader(void) const
virtual void Print(std::ostream &os) const
Print the item contents.

QueueDiscItem is the abstract base class for items that are stored in a queue disc.
Definition: queue-item.h:133
Every class exported by the ns3 library is enclosed in the ns3 namespace.
