erases a Route with the same faceId and origin

Definition at line 66 of file rib-entry.cpp.

RibEntry::RouteList::iterator nfd::rib::RibEntry::eraseRoute ( RouteList::iterator  route)

erases a Route with the passed iterator

Returns
{ an iterator to the element that followed the erased iterator }

Definition at line 111 of file rib-entry.cpp.

RibEntry::RouteList::const_iterator nfd::rib::RibEntry::findInheritedRoute ( const Route route) const

Finds an inherited route with a matching face ID.

Returns
{ An iterator to the matching route if one is found; otherwise, an iterator to the end of the entry's inherited route list }

const RibEntry::RouteList & nfd::rib::RibEntry::getInheritedRoutes ( ) const

Returns the routes this namespace has inherited.

The inherited routes returned represent inherited routes this namespace has in the FIB.

Returns
{ routes inherited by this namespace }

ndn::PrefixAnnouncement nfd::rib::RibEntry::getPrefixAnnouncement ( time::milliseconds  minExpiration = 15_s,
time::milliseconds  maxExpiration = 1_h 
) const

Retrieve a prefix announcement suitable for readvertising this route.

If one or more routes in this RIB entry contains a prefix announcement, this method returns the announcement from the route that expires last.

If this RIB entry does not have a route containing a prefix announcement, this method creates a new announcement. Its expiration period reflects the remaining lifetime of this RIB entry, confined within [minExpiration, maxExpiration] range. The caller is expected to sign this announcement.

Warning
(minExpiration > maxExpiration) triggers undefined behavior.

std::pair< RibEntry::iterator, bool > nfd::rib::RibEntry::insertRoute ( const Route route)

inserts a new route into the entry's route list If another route already exists with the same faceId and origin, the new route is not inserted.

Returns
a pair, whose first element is the iterator to the newly inserted element if the insert succeeds and to the previously-existing element otherwise, and whose second element is true if the insert succeeds and false otherwise.
