Member Function Documentation

getIncomingNack()

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 47 of file pit-out-record.hpp.

References setIncomingNack().

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 pointer previously returned by .getIncomingNack() .

clearIncomingNack()

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

inline

clears last NACK

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