Detailed Description

contains information about an Interest toward an outgoing face

Definition at line 36 of file pit-out-record.hpp.

Constructor & Destructor Documentation

nfd::pit::OutRecord::OutRecord ( Face &  face )

explicit

Definition at line 31 of file pit-out-record.cpp.

Member Function Documentation

void nfd::pit::OutRecord::clearIncomingNack ( )

inline

clears last NACK

This is invoked in outgoing Interest pipeline. This invalidates any pointer previously returned by .getIncomingNack() .

Definition at line 70 of file pit-out-record.hpp.

void nfd::StrategyInfoHost::clearStrategyInfo ( )

inherited

clear all StrategyInfo items

Definition at line 31 of file strategy-info-host.cpp.

template<typename T >

size_t nfd::StrategyInfoHost::eraseStrategyInfo ( )

inlineinherited

erase a StrategyInfo item

Template Parameters

T	type of StrategyInfo, must be a subclass of fw::StrategyInfo

Returns

number of items erased

Definition at line 82 of file strategy-info-host.hpp.

time::steady_clock::TimePoint nfd::pit::FaceRecord::getExpiry ( ) const

inlineinherited

gives the time point this record expires

Returns

getLastRenewed() + InterestLifetime

Definition at line 92 of file pit-face-record.hpp.

Face & nfd::pit::FaceRecord::getFace ( ) const

inlineinherited

Definition at line 74 of file pit-face-record.hpp.

const lp::NackHeader* nfd::pit::OutRecord::getIncomingNack ( ) const

inline

Returns

last NACK returned by getFace()

A nullptr return value means the Interest is still pending or has timed out. A non-null return value means the last outgoing Interest has been NACKed.

Definition at line 48 of file pit-out-record.hpp.

uint32_t nfd::pit::FaceRecord::getLastNonce ( ) const

inlineinherited

Definition at line 80 of file pit-face-record.hpp.

time::steady_clock::TimePoint nfd::pit::FaceRecord::getLastRenewed ( ) const

inlineinherited

Definition at line 86 of file pit-face-record.hpp.

template<typename T >

T* nfd::StrategyInfoHost::getStrategyInfo ( ) const

inlineinherited

get a StrategyInfo item

Template Parameters

T	type of StrategyInfo, must be a subclass of fw::StrategyInfo

Returns

an existing StrategyInfo item of type T, or nullptr if it does not exist

Definition at line 44 of file strategy-info-host.hpp.

template<typename T , typename... A>

std::pair<T*, bool> nfd::StrategyInfoHost::insertStrategyInfo ( A &&...  args )

inlineinherited

insert a StrategyInfo item

Template Parameters

T	type of StrategyInfo, must be a subclass of fw::StrategyInfo

Returns

a new or existing StrategyInfo item of type T, and true for new item, false for existing item

Definition at line 63 of file strategy-info-host.hpp.

bool nfd::pit::OutRecord::setIncomingNack

(

const lp::Nack &

nack

)

sets a NACK received from getFace()

Returns

whether incoming NACK is accepted

This is invoked in incoming NACK pipeline. An incoming NACK is accepted if its Nonce matches getLastNonce(). If accepted, nack.getHeader() will be copied, and any pointer previously returned by .getIncomingNack() .

Definition at line 37 of file pit-out-record.cpp.

void nfd::pit::FaceRecord::update ( const Interest &  interest )

inherited

updates lastNonce, lastRenewed, expiry fields

Definition at line 40 of file pit-face-record.cpp.
