Member Function Documentation

void nfd::fw::MulticastStrategy::afterReceiveInterest ( const Face &  inFace,
const Interest &  interest,
shared_ptr< fib::Entry >  fibEntry,
shared_ptr< pit::Entry >  pitEntry 
)
virtual

trigger after Interest is received

The Interest:

  • does not violate Scope
  • is not looped
  • cannot be satisfied by ContentStore
  • is under a namespace managed by this strategy

The strategy should decide whether and where to forward this Interest.

  • If the strategy decides to forward this Interest, invoke this->sendInterest one or more times, either now or shortly after
  • If strategy concludes that this Interest cannot be forwarded, invoke this->rejectPendingInterest so that PIT entry will be deleted shortly
Note
The strategy is permitted to store a weak reference to fibEntry. Do not store a shared reference, because PIT entry may be deleted at any moment. fibEntry is passed by value to allow obtaining a weak reference from it.
The strategy is permitted to store a shared reference to pitEntry. pitEntry is passed by value to reflect this fact.

Implements nfd::fw::Strategy.

Reimplemented in nfd::fw::BroadcastStrategy.
