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 40 of file tcp-channel.cpp.

Member Function Documentation

◆ 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.

Definition at line 75 of file tcp-channel.cpp.

◆ getDefaultMtu()

size_t nfd::face::Channel::getDefaultMtu ( ) const

inlinenoexceptinherited

Returns the default MTU for all faces created by this channel.

Definition at line 56 of file channel.hpp.

◆ getUri()

const FaceUri& nfd::face::Channel::getUri ( ) const

inlinenoexceptinherited

Definition at line 47 of file channel.hpp.

◆ isListening()

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

inlinefinalvirtual

Returns whether the channel is listening.

Implements nfd::face::Channel.

Definition at line 62 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

onFaceCreated	Callback to notify successful creation of the face
onAcceptFailed	Callback to notify when channel fails (accept call returns an error)
backlog	The maximum length of the queue of pending incoming connections
