Detailed Description

generalization of a network interface

A face generalizes a network interface. It provides best-effort network-layer packet delivery services on a physical interface, an overlay tunnel, or a link to a local application.

A face combines two parts: LinkService and Transport. Transport is the lower part, which provides best-effort TLV block deliveries. LinkService is the upper part, which translates between network-layer packets and TLV blocks, and may provide additional services such as fragmentation and reassembly.

Returns: a FaceUri representing remote endpoint

ndn::nfd::FaceScope nfd::face::Face::getScope ( ) const

inline

Returns: whether face is local or non-local for scope control purpose

Definition at line 265 of file face.hpp.

ndn::nfd::FacePersistency nfd::face::Face::getPersistency ( ) const

inline

Returns: face persistency setting

Definition at line 271 of file face.hpp.

void nfd::face::Face::setPersistency ( ndn::nfd::FacePersistency persistency )

inline

changes face persistency setting

Definition at line 277 of file face.hpp.

inline

Returns: whether face is point-to-point or multi-access

Definition at line 283 of file face.hpp.

FaceState nfd::face::Face::getState ( ) const

inline

Returns: face state

Definition at line 289 of file face.hpp.

time::steady_clock::TimePoint nfd::face::Face::getExpirationTime ( ) const

inline

Returns: expiration time of the face

Return values

time::steady_clock::TimePoint::max() the face has an indefinite lifetime

Definition at line 295 of file face.hpp.

void nfd::face::Face::close ( )

inline

request the face to be closed

This operation is effective only if face is in UP or DOWN state, otherwise it has no effect. The face changes state to CLOSING, and performs cleanup procedure. The state will be changed to CLOSED when cleanup is complete, which may happen synchronously or asynchronously.

Warning: the face must not be deallocated until its state changes to CLOSED
