Detailed Description

Class implementing UDP-based channel to create faces.

Definition at line 40 of file udp-channel.hpp.

Constructor & Destructor Documentation

◆ UdpChannel()

nfd::face::UdpChannel::UdpChannel ( const udp::Endpoint localEndpoint,
time::nanoseconds  idleTimeout,
bool  wantCongestionMarking 
)

Create a UDP channel on the given localEndpoint.

To enable creation of faces upon incoming connections, one needs to explicitly call UdpChannel::listen method. The created socket is bound to localEndpoint.

Definition at line 38 of file udp-channel.cpp.

References NFD_LOG_CHAN_INFO, and nfd::face::Channel::setUri().

Member Function Documentation

◆ isListening()

bool nfd::face::UdpChannel::isListening ( ) const
inlineoverridevirtual

Returns whether the channel is listening.

Implements nfd::face::Channel.

Definition at line 55 of file udp-channel.hpp.

Referenced by listen().

◆ size()

size_t nfd::face::UdpChannel::size ( ) const
inlineoverridevirtual

Returns the number of faces in the channel.

Implements nfd::face::Channel.

Definition at line 61 of file udp-channel.hpp.

◆ connect()

void nfd::face::UdpChannel::connect ( const udp::Endpoint remoteEndpoint,
const FaceParams params,
const FaceCreatedCallback onFaceCreated,
const FaceCreationFailedCallback onConnectFailed 
)

Create a unicast UDP face toward remoteEndpoint.

Definition at line 51 of file udp-channel.cpp.

References NFD_LOG_CHAN_DEBUG.

◆ listen()

void nfd::face::UdpChannel::listen ( const FaceCreatedCallback onFaceCreated,
const FaceCreationFailedCallback onFaceCreationFailed 
)

Start listening.

Enable listening on the local endpoint, waiting for incoming datagrams, and creating a face when a datagram is received from a new remote host.

Faces created in this way will have on-demand persistency.

Parameters
onFaceCreatedCallback to notify successful creation of a face
onFaceCreationFailedCallback to notify errors
