void ns3::dsdv::RoutingProtocol::DoDispose ( void  )
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.

It is safe to call GetObject from within this method.

Ptr< Ipv4Route > ns3::dsdv::RoutingProtocol::RouteOutput ( Ptr< Packet p,
const Ipv4Header header,

)
virtual

Query routing cache for an existing route, for an outbound packet.

This lookup is used by transport protocols. It does not cause any packet to be forwarded, and is synchronous. Can be used for multicast or unicast. The Linux equivalent is ip_route_output()

The header input parameter may have an uninitialized value for the source address, but the destination address should always be properly set by the caller.

Parameters
ppacket to be routed. Note that this method may modify the packet. Callers may also pass in a null pointer.
headerinput parameter (used to form key to search for the route)
oifOutput interface Netdevice. May be zero, or may be bound via socket options to a particular output interface.
sockerrOutput parameter; socket errno
Returns
a code that indicates what happened in the lookup
