Member Function Documentation

PathAttribute * UnknownAttribute::clone ( ) const [virtual]

Make a copy of the current attribute.

The derived class should use new to generate a copy of itself. The wire format representation will not be used by the caller.

Implements PathAttribute.

bool UnknownAttribute::encode ( uint8_t *  buf,
size_t &  wire_size,
const BGPPeerData peerdata 
) const [virtual]

encode a path attribute.

In a sane world, we'd use a virtual function for this. But we store so many path attributes that we can't afford the overhead of a virtual function table for them, so we have to do this the hard way

XXX THE ABOVE IS NO LONGER THE CASE. WE SHOULD REWRITE THIS TO USE VIRTUAL FUNCTIONS

Implements PathAttribute.

string UnknownAttribute::str ( ) const [virtual]

We need to encode an attribute to send to a peer.

However we only have the canonically encoded byte stream data for it. Sometimes that is fine, and we should just send that; sometimes we need to decode and re-encode for this specific peer.

Reimplemented from PathAttribute.
