ExternalRouteOrderPred

bool  operator() (const OlsrTypes::ExternalID lhid, const OlsrTypes::ExternalID rhid)

operator()

Functor to: implement collation order on external route maps.

12.6: The distance to the last-hop, as measured from the HNA message, is used as the current discriminator; this is what's specified in the RFC.

Because identifiers for these structures are normally passed around rather than the pointers themselves, it is necessary to use a functor.

Collation order: 1. Network destination, as per IPvXNet. 2. If not self originated, distance in ascending order.

Parameters:

lhidthe ID of the external route on the left-hand side.
rhidthe ID of the external route on the right-hand side.

Returns: true if lhid comes before rhid.
