Detailed Description

Stores a pending Interest and associated callbacks.

Constructor & Destructor Documentation

PendingInterest() [1/2]

ndn::PendingInterest::PendingInterest ( shared_ptr< const Interest >  interest, const DataCallback &  dataCallback, const NackCallback &  nackCallback, const TimeoutCallback &  timeoutCallback, Scheduler &  scheduler  )

inline

Construct a pending Interest record for an Interest from Face::expressInterest.

The timeout is set based on the current time and InterestLifetime. This class will invoke the timeout callback unless the record is deleted before timeout.

Parameters

interest	the Interest
dataCallback	invoked when matching Data packet is received
nackCallback	invoked when Nack matching Interest is received
timeoutCallback	invoked when Interest times out
scheduler	Scheduler for scheduling the timeout event

Definition at line 73 of file pending-interest.hpp.

PendingInterest() [2/2]

ndn::PendingInterest::PendingInterest ( shared_ptr< const Interest >  interest, Scheduler &  scheduler  )

inline

Construct a pending Interest record for an Interest from NFD.

Parameters

interest	the Interest
scheduler	Scheduler for scheduling the timeout event

Definition at line 94 of file pending-interest.hpp.

Member Function Documentation

getInterest()

shared_ptr<const Interest> ndn::PendingInterest::getInterest ( ) const

inline

Get the Interest.

Definition at line 106 of file pending-interest.hpp.

Referenced by ndn::InterestFilterRecord::doesMatch().

getOrigin()

PendingInterestOrigin ndn::PendingInterest::getOrigin ( ) const

inline

Definition at line 112 of file pending-interest.hpp.

Referenced by ndn::InterestFilterRecord::doesMatch().

recordForwarding()

void ndn::PendingInterest::recordForwarding ( )

inline

Record that the Interest has been forwarded to one destination.

A "destination" could be either a local InterestFilter or the forwarder.

Definition at line 123 of file pending-interest.hpp.

Referenced by ndn::Face::Impl::dispatchInterest().

recordNack()

optional<lp::Nack> ndn::PendingInterest::recordNack ( const lp::Nack &  nack )

inline

Record an incoming Nack against a forwarded Interest.

Returns

least severe Nack if all destinations where the Interest was forwarded have Nacked; otherwise, nullopt

Definition at line 134 of file pending-interest.hpp.

References ndn::lp::Nack::getReason(), ndn::lp::isLessSevere(), and nonstd::optional_lite::nullopt.

invokeDataCallback()

void ndn::PendingInterest::invokeDataCallback ( const Data &  data )

inline

Invoke the Data callback.

Note

This method does nothing if the Data callback is empty

Definition at line 151 of file pending-interest.hpp.

invokeNackCallback()

void ndn::PendingInterest::invokeNackCallback ( const lp::Nack &  nack )

inline

Invoke the Nack callback.

Note

This method does nothing if the Nack callback is empty

Definition at line 163 of file pending-interest.hpp.

setDeleter()

void ndn::PendingInterest::setDeleter ( const std::function< void()> &  deleter )

inline

Set cleanup function to be invoked when Interest times out.

Definition at line 174 of file pending-interest.hpp.
