Detailed Description

Class implementing TCP-based channel to create faces.

Channel can create faces as a response to incoming TCP connections (TcpChannel::listen needs to be called for that to work) or explicitly after using TcpChannel::connect method.

Definition at line 49 of file tcp-channel.hpp.

Constructor & Destructor Documentation

◆ TcpChannel()

nfd::face::TcpChannel::TcpChannel ( const tcp::Endpoint localEndpoint,
bool  wantCongestionMarking,
DetermineFaceScopeFromAddress  determineFaceScope 
)

Create TCP channel for the local endpoint.

To enable creation faces upon incoming connections, one needs to explicitly call TcpChannel::listen method.

Definition at line 39 of file tcp-channel.cpp.

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

Member Function Documentation

◆ isListening()

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

Returns whether the channel is listening.

Implements nfd::face::Channel.

Definition at line 62 of file tcp-channel.hpp.

Referenced by listen().

◆ size()

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

Returns the number of faces in the channel.

Implements nfd::face::Channel.

Definition at line 68 of file tcp-channel.hpp.

◆ listen()

void nfd::face::TcpChannel::listen ( const FaceCreatedCallback onFaceCreated,
const FaceCreationFailedCallback onAcceptFailed,
int  backlog = boost::asio::ip::tcp::acceptor::max_connections 
)

Enable listening on the local endpoint, accept connections, and create faces when remote host makes a connection.

Parameters
onFaceCreatedCallback to notify successful creation of the face
onAcceptFailedCallback to notify when channel fails (accept call returns an error)
backlogThe maximum length of the queue of pending incoming connections

Definition at line 52 of file tcp-channel.cpp.

References isListening(), NFD_LOG_CHAN_DEBUG, and NFD_LOG_CHAN_WARN.

◆ connect()

void nfd::face::TcpChannel::connect ( const tcp::Endpoint remoteEndpoint,
const FaceParams params,
const FaceCreatedCallback onFaceCreated,
const FaceCreationFailedCallback onConnectFailed,
time::nanoseconds  timeout = 8_s 
)

Create a face by establishing a TCP connection to remoteEndpoint.
