virtual int32_t DoClassify(Ptr< QueueDiscItem > item) const =0
Classify a packet.
static const int PF_NO_MATCH
Standard value used by packet filters to indicate that no match was possible.
Definition: packet-filter.h:48
virtual ~PacketFilter()
virtual bool CheckProtocol(Ptr< QueueDiscItem > item) const =0
Checks if the filter is able to classify a kind of items.
Smart pointer class similar to boost::intrusive_ptr.
