Member Function Documentation

clearIncomingNack()

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

inlinenoexcept

Clears last Nack.

This is invoked in outgoing Interest pipeline.

Any pointers previously returned by getIncomingNack() are invalidated.

Definition at line 166 of file pit-entry.hpp.

clearStrategyInfo()

void nfd::StrategyInfoHost::clearStrategyInfo ( )

inlineinherited

Clear all StrategyInfo items.

Definition at line 92 of file strategy-info-host.hpp.

eraseStrategyInfo()

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.

FaceRecord()

nfd::pit::FaceRecord::FaceRecord

inlineexplicit

Definition at line 57 of file pit-entry.hpp.

getExpiry()

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

inlinenoexceptinherited

Returns the time point at which this record expires.

Returns

getLastRenewed() + InterestLifetime

Definition at line 85 of file pit-entry.hpp.

getFace()

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

inlinenoexceptinherited

Definition at line 63 of file pit-entry.hpp.

getIncomingNack()

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

inlinenoexcept

Returns the 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 140 of file pit-entry.hpp.

getLastNonce()

Interest::Nonce nfd::pit::FaceRecord::getLastNonce ( ) const

inlinenoexceptinherited

Definition at line 69 of file pit-entry.hpp.

getLastRenewed()

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

inlinenoexceptinherited

Definition at line 75 of file pit-entry.hpp.

getStrategyInfo()

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 46 of file strategy-info-host.hpp.

insertStrategyInfo()

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 64 of file strategy-info-host.hpp.

setIncomingNack()

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 pointers previously returned by getIncomingNack() are invalidated.

Definition at line 52 of file pit-entry.cpp.

update()

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

inherited

Updates lastNonce, lastRenewed, expiry fields.

Definition at line 33 of file pit-entry.cpp.
