◆ DoDispose()

void ns3::lrwpan::LrWpanMac::DoDispose ( )

overrideprotectedvirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.

Reimplemented from ns3::Object.

Here is the call graph for this function:

◆ DoInitialize()

void ns3::lrwpan::LrWpanMac::DoInitialize ( )

overrideprotectedvirtual

Initialize() implementation.

This method is called only once by Initialize(). If the user calls Initialize() multiple times, DoInitialize() is called only the first time.

Subclasses are expected to override this method and chain up to their parent's implementation once they are done. It is safe to call GetObject() and AggregateObject() from within this method.

◆ m_promiscSnifferTrace

TracedCallback<Ptr<const Packet> > ns3::lrwpan::LrWpanMac::m_promiscSnifferTrace

private

A trace source that emulates a promiscuous mode protocol sniffer connected to the device.

This trace source fire on packets destined for any host just like your average everyday packet sniffer.

On the transmit size, this trace hook will fire after a packet is dequeued from the device queue for transmission. In Linux, for example, this would correspond to the point just before a device hard_start_xmit where dev_queue_xmit_nit is called to dispatch the packet to the PF_PACKET ETH_P_ALL handlers.

On the receive side, this trace hook will fire when a packet is received, just before the receive callback is executed. In Linux, for example, this would correspond to the point at which the packet is dispatched to packet sniffers in netif_receive_skb.
