void ns3::WifiNetDevice::CompleteConfig ( void   )  [private]
void ns3::WifiNetDevice::DoDispose ( void   )  [private, virtual]

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

Subclasses are expected to implement their real destruction code in an overriden 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.

Reimplemented from ns3::Object.

Address ns3::WifiNetDevice::GetMulticast ( Ipv6Address  addr  )  const [virtual]

Parameters:
addr IPv6 address

Warning:

Implements ns3::NetDevice.

References GetMulticast().

Address ns3::WifiNetDevice::GetMulticast ( Ipv4Address  multicastGroup  )  const [virtual]

Make and return a MAC multicast address using the provided multicast group.

RFC 1112 says that an Ipv4 host group address is mapped to an Ethernet multicast address by placing the low-order 23-bits of the IP address into the low-order 23 bits of the Ethernet multicast address 01-00-5E-00-00-00 (hex). Similar RFCs exist for Ipv6 and Eui64 mappings. This method performs the multicast address creation function appropriate to the underlying MAC address of the device. This MAC address is encapsulated in an abstract Address to avoid dependencies on the exact MAC address format.

A default imlementation of GetMulticast is provided, but this method simply NS_ASSERTS. In the case of net devices that do not support multicast, clients are expected to test NetDevice::IsMulticast and avoid attempting to map multicast packets. Subclasses of NetDevice that do support multicasting are expected to override this method and provide an implementation appropriate to the particular device.

Parameters:
multicastGroup The IP address for the multicast group destination of the packet.
Returns:
The MAC multicast Address used to send packets to the provided multicast group.
Warning:
Calling this method is invalid if IsMulticast returns not true.
